1. Foot and Ankle
a. Achilles Tendonopathy/or Injury and
Rupture (ALTERNATE SPELLING: "TENDINOPATHY"):
i. Description/Definition: Rupture or tear of
Achilles tendon or insertional or non-insertional tendonopathy.
ii. Occupational Relationship: Tears or
ruptures are related to a fall, twisting, jumping, or sudden load on ankle with
dorsiflexion. Tendonopathy may be exacerbated by continually walking on hard
surfaces.
iii. Specific Physical
Exam Findings: Swelling and pain at tendon, sometimes accompanied by crepitus
and pain with passive motion. Rupture or partial tear may present with palpable
deficit in tendon. If there is a full tear, Thompson test will usually be
positive. A positive Thompson's test is lack of plantar flexion with
compression of the calf when the patient is prone with the knee
flexed.
iv. Diagnostic Testing
Procedures: Radiography may be performed to identify Haglund's deformity;
however, many Haglund's deformities are asymptomatic. MRI or ultrasound may be
performed if surgery is being considered for tendonopathy or rupture.
v. Non-operative Treatment Procedures:
(a). Initial Treatment: Cast in non
weight-bearing for tears. Protected weight-bearing for other
injuries.
(b). Medications such as
analgesics and anti-inflammatories may be helpful. Refer to medication
discussions in Medications and Medical Management.
(c). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management.
(d). Benefits may be achieved through
therapeutic rehabilitation and rehabilitation interventions. Eccentric training
alone or with specific bracing may be used for tendonopathy. Manual therapy may
also be used. Therapy will usually include range-of-motion (ROM), active
therapies, and a home exercise program. Active therapies include,
proprioception training, restoring normal joint mechanics, and clearing
dysfunctions from adjacent structures. Passive as well as active therapies may
be used for control of pain and swelling. Therapy should progress to
strengthening and an independent home exercise program targeted to further
improve ROM, strength, and normal joint mechanics influenced by distal and
proximal structures. Refer to Therapeutic Procedures, Non-operative.
(i). Passive modalities are most effective as
adjunctive treatments to improve the results of active treatment. They may be
used as found in Therapeutic Procedures, Non-operative.
(e). Steroid injections should generally be
avoided in these patients since this is a risk for later rupture.
(f). Return to work with appropriate
restrictions should be considered early in the course of treatment. Refer to
Return to Work.
(g). Other
therapies in Therapeutic Procedures, Non-operative may be employed in
individual cases.
vi.
Surgical Indications/Considerations: Total or partial rupture.
(a). Smoking may affect soft tissue healing
through tissue hypoxia. Patients should be strongly encouraged to stop smoking
and be provided with appropriate counseling by the physician.
vii. Operative Procedures: Repair
of tendons open or percutaneously with or without anchors may be required.
Tendon grafts are used for chronic cases or primary surgery failures when
tendon tissue is poor.
viii.
Post-operative Treatment:
(a). An
individualized rehabilitation program based upon communication between the
surgeon and the therapist using therapies as outlined in Section F, Therapeutic
Procedures, Non-operative.
(b).
Treatment may include the following: restricted weight-bearing, bracing, active
therapy with or without passive therapy.
(c). Range of motion may begin at three weeks
depending on wound healing. Therapy and some restrictions will usually continue
for six to eight weeks.
(d). Return
to work and restrictions after surgery may be made by an attending physician
experienced in occupational medicine in consultation with the surgeon or by the
surgeon.
b.
Aggravated Osteoarthritis:
i.
Description/Definition: Internal joint pathology of ankle.
ii. Occupational Relationship: The provider
must establish the occupational relationship by establishing a change in the
patient's baseline condition and a relationship to work activities, for example
frequent jumping, climbing, or squatting.
(a).
Other causative factors to consider: Prior significant injury to the ankle may
predispose the joint to osteoarthritis. In order to entertain previous trauma
as a cause, the patient should have a medically documented injury with
radiographs or MRI showing the level of anatomic change. The prior injury
should have been at least two years from the presentation for the new
complaints and there should be a significant increase of pathology on the
affected side in comparison to the original imaging or operative reports and/or
the opposite un-injured extremity.
iii. Specific Physical Exam Findings: Pain
within joint, swelling. Crepitus, locking of the joint, reduced range of
motion, pain with stress tests, angular deformities.
iv. Diagnostic Testing Procedures: X-ray
mechanical axis views, CT, MRI, diagnostic injection.
v. Non-operative Treatment Procedures:
(a). Initial Treatment: May include orthoses,
custom shoes with rocker bottom shoe inserts, and braces. Cane may also be
useful.
(b). Medications such as
analgesics and anti-inflammatories may be helpful. Refer to medication
discussions in Medications and Medical Management.
(c). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management.
(d). Benefits may be achieved through
therapeutic rehabilitation and rehabilitation interventions. They should
include range-of-motion (ROM), active therapies, and a home exercise program.
Active therapies include, proprioception training, restoring normal joint
mechanics, and clearing dysfunctions from adjacent structures. Passive as well
as active therapies may be used for control of pain and swelling. Therapy
should progress to strengthening and an independent home exercise program
targeted to further improve ROM, strength, and normal joint mechanics
influenced by distal and proximal structures. Refer to Therapeutic Procedures,
Non-operative.
(i). Passive modalities are
most effective as adjunctive treatments to improve the results of active
treatment. They may be used as found in Therapeutic Procedures,
Non-operative.
(e).
Steroid injections may decrease inflammation and allow the therapist to
progress with functional exercise and range of motion. Steroid injections under
significant pressure should be avoided as the needle may be penetrating the
tendon and injection into the tendon can cause possible tendon breakdown,
tendon degeneration, or rupture. Injections should be minimized for patients
under 30 years of age.
(i). Time to Produce
Effect: One injection.
(ii).
Maximum Duration: Three injections in one year spaced at least four to eight
weeks apart.
(iii). Steroid
injections should be used cautiously in diabetic patients. Diabetic patients
should be reminded to check their blood glucose levels at least daily for two
weeks after injections.
(f). Return to work with appropriate
restrictions should be considered early in the course of treatment. Refer to
Return to Work.
(g). Other
therapies in Therapeutic Procedures, Non-operative may be employed in
individual cases.
vi.
Surgical Indications/Considerations:
(a). The
patient is a good surgical candidate and pain continues to interfere with ADLs
after non-surgical interventions including weight control, therapy with active
patient participation, and medication.
(b). Refer to Therapeutic
Procedures-Operative, for specific indications for osteotomy, ankle fusion or
arthroplasty.
(c). Implants are
less successful than similar procedures in the knee or hip. There are no
quality studies comparing arthrodesis and ankle replacement. Patients with
ankle fusions generally have good return to function and fewer complications
than those with joint replacements. Salvage procedures for ankle replacement
include revision with stemmed implant or allograft fusion. Given these factors,
an ankle arthroplasty requires prior authorization and a second opinion by a
surgeon specializing in lower extremity surgery.
(d). Prior to surgical intervention, the
patient and treating physician should identify functional operative goals and
the likelihood of achieving improved ability to perform activities of daily
living or work activities and the patient should agree to comply with the pre-
and post-operative treatment plan including home exercise. The provider should
be especially careful to make sure the patient understands the amount of
post-operative therapy required and the length of partial- and full-disability
expected post-operatively.
(e). In
cases where surgery is contraindicated due to obesity, it may be appropriate to
recommend a weight loss program if the patient is unsuccessful losing weight on
their own. Coverage for weight loss would continue only for motivated patients
who have demonstrated continual progress with weight loss.
(f). Because smokers have a higher risk of
non-union and post-operative costs, it is recommended that carriers cover a
smoking cessation program peri-operatively. Physicians may monitor smoking
cessation with laboratory tests such as cotinine levels for long-term
cessation.
vii.
Operative Procedures: Arthroscopy, ankle arthroplasty or fusion. Supramalleolar
osteotomies can be considered for patients with deformities or pre-existing
hind foot varus or valgus deformities.
viii. Post-operative Treatment
(a). An individualized rehabilitation program
based upon communication between the surgeon and the therapist using therapies
as outlined in Section F, Therapeutic Procedures, Non-operative.
(b). In all cases, communication between the
physician and therapist is important to the timing of weight-bearing and
exercise progressions.
(c).
Treatment may include the following: restricted weight-bearing, bracing, gait
training and other active therapy with or without passive therapy.
(d). Refer to Ankle Fusion, Osteotomy, or
Arthroplasty for further specific information.
(e). Return to work and restrictions after
surgery may be made by an attending physician experienced in occupational
medicine in consultation with the surgeon or by the surgeon.
c. Ankle or Subtalar
Joint Dislocation:
i. Description/Definition:
Dislocation of ankle or subtalar joint.
ii. Occupational Relationship: Usually occurs
with falling or twisting.
iii.
Specific Physical Exam Findings: Disruption of articular arrangements of ankle,
subtalar joint may be tested using ligamentous laxity tests.
iv. Diagnostic Testing Procedures:
Radiographs, CT scans. MRI may be used to assess for avascular necrosis of the
talus which may occur secondary to a dislocation.
v. Non-operative Treatment Procedures:
(a). Initial Treatment: Closed reduction
under anesthesia with pre- and post-reduction neurovascular assessment followed
by casting and weight-bearing limitations.
(b). Medications such as analgesics and
anti-inflammatories may be helpful. Refer to medication discussions in
Medications and Medical Management.
(c). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management.
(d). Benefits may be achieved through
therapeutic rehabilitation and rehabilitation interventions. They should
include range of motion (ROM), active therapies, and a home exercise program.
Active therapies include, proprioception training, restoring normal joint
mechanics, and clearing dysfunctions from adjacent structures. Passive as well
as active therapies may be used for control of pain and swelling. Therapy
should progress to strengthening and an independent home exercise program
targeted to further improve ROM, strength, and normal joint mechanics
influenced by distal and proximal structures. Refer to Therapeutic Procedures,
Non-operative.
(i). Passive modalities are
most effective as adjunctive treatments to improve the results of active
treatment. They may be used as found in Therapeutic Procedures,
Non-operative.
(e).
Return to work with appropriate restrictions should be considered early in the
course of treatment. Refer to Return to Work.
(f). Other therapies in Therapeutic
Procedures, Non-operative may be employed in individual cases.
vi. Surgical
Indications/Considerations: Inability to reduce closed fracture, association
with unstable fractures
vii.
Operative Procedures: Open or closed reduction of dislocation.
viii. Post-operative Treatment:
(a). An individualized rehabilitation program
based upon communication between the surgeon and the therapist using therapies
as outlined in Therapeutic Procedures, Non-operative.
(b). Treatment usually includes initial
immobilization with restricted weight-bearing, followed by bracing and active
therapy with or without passive therapy.
(c). Return to work and restrictions after
surgery may be made by an attending physician experienced in occupational
medicine in consultation with the surgeon or by the surgeon.
d. Ankle
Sprain/Fracture
i. Description/Definition. An
injury to the ankle joint due to abnormal motion of the talus that causes a
stress on the malleolus and the ligaments. Injured ligaments in order of
disruption include the anterior talofibular ligament (ATFL), calcaneofibular
ligament (CFL), posterior talofibular ligament (PTFL), deltoid ligaments, and
syndesmotic ligaments. Instability can result from a fracture of a malleolus
(malleolli), rupture of ligaments, or a combination. Circumstances surrounding
the injury, including consideration of location and additional injuries are of
importance. Additionally, the position of the foot at the time of injury is
helpful in determining the extent and type of injury. Grading of soft tissue
injuries includes:
(a). Grade 1 Injury: those
with overstretching or microscopic tears of the ligament, minimal swelling,
normal stress testing, and the ability to bear weight.
(b). Grade 2 Injury: have partial disruption
of the ligament, significant swelling, indeterminate results on stress testing,
and difficulty bearing weight.
(c).
Grade 3 Injury: have a ruptured ligament, swelling and ecchymosis, abnormal
results on stress testing, and the inability to bear weight. May also include a
chip avulsion fracture on x-ray.
ii. Occupational Relationship: sudden
twisting, direct blunt trauma and falls. Inversion of the ankle with a
plantar-flexed foot is the most common mechanism of injury.
iii. Specific Physical Exam Findings: varies
with individual. With lower grade sprains the ankle may be normal appearing
with minimal tenderness on examination. The ability/inability to bear weight,
pain, swelling, or ecchymosis should be noted. If the patient is able to
transfer weight from one foot onto the affected foot and has normal physical
findings, then likelihood of fracture is reduced. Stress testing using the
anterior drawer stress test, the talar tilt test and the external rotation
stress test may be normal or abnormal depending on the involved ligament.
(a). Syndesmotic injury can occur with
external rotation injuries and requires additional treatment. Specific physical
exam tests include the squeeze test and external rotation at neutral.
iv. Diagnostic Testing Procedures:
Radiographs. Refer to Initial Diagnostic Section which generally follows the
Ottawa Ankle Rules. The Ottawa Ankle Rules are a decision aid for radiography.
Commonly missed conditions include ankle syndesmosis or fractures. The
instrument has a sensitivity of almost 100 percent and a modest specificity,
and its use should reduce the number of unnecessary radiographs by 30 to 40
percent.
(a). For an acute, unstable ankle or
a repeat or chronic ankle injury, a MRI and/or diagnostic injection may be
ordered. Arthroscopy can be used in unusual cases with persistent functional
instability and giving way of the ankle, after conservative treatment, to
directly visualize the ruptured ligament(s).
v. Non-operative Treatment Procedures
(a). Initial treatment for patients able to
bear weight: NSAIDs, RICE (rest, ice, compression and elevation), and early
functional bracing is used. In addition, crutches may be beneficial for
comfort. Early functional treatment including range of motion and strengthening
exercises along with limited weight-bearing, are preferable to strict
immobilization with rigid casting for improving outcome and reducing time to
return to work.
(b). Initial
treatment for patients unable to bear weight: bracing plus NSAIDs and RICE are
used. When patient becomes able to bear weight a walker boot is frequently
employed. There is no clear evidence favoring ten days of casting over
pneumatic bracing as initial treatment for patients who cannot bear weight
three days post injury. There is good evidence that use of either device
combined with functional therapy results in similar long-term recovery.
(i). There is some evidence that functional
rehabilitation has results superior to six weeks of immobilization.
(ii). Small avulsion fractures of the fibula
with minimal or no displacement can be treated as an ankle sprain.
(iii). For patients with a clearly unstable
joint, immobilize with a short leg plaster cast or splint for two to six weeks
along with early weight-bearing.
(c). Balance/coordination training is a
well-established treatment which improves proprioception and may decrease
incidence of recurrent sprains.
(d). Medications such as analgesics and
anti-inflammatories may be helpful. Refer to medication discussions in
Medications and Medical Management.
(e). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management.
(f). Heel wedges or other orthotics may be
used for rear foot varus or valgus deformities.
(i). There is good evidence that semi-rigid
orthoses or pneumatic braces prevent ankle sprains during high risk physical
activities and they should be used as appropriate after acute
sprains.
(g). When
fractures are involved refer to comments related to osteoporosis in Therapeutic
Procedures, Non-operative, Osteoporosis Management.
(h). Smoking may affect fracture healing.
Patients should be strongly encouraged to stop smoking and be provided with
appropriate counseling by the physician.
(i). Return-to-work with appropriate
restrictions should be considered early in the course of treatment. Refer to
Return to Work.
(j). Other
therapies in Therapeutic Procedures, Non-operative, including manual therapy
may be employed in individual cases.
(k). Hyperbaric oxygen therapy is not
recommended.
vi.
Surgical Indications/Considerations:
(a).
Acute surgical indications include sprains with displaced fractures,
syndesmotic disruption or ligament sprain associated with a fracture causing
instability.
(b). There is no
conclusive evidence that surgery as opposed to functional treatment for an
uncomplicated Grade I-III ankle sprain improves patient outcome.
(c). Chronic indications are functional
problems, such as recurrent instability, remaining after at least 2 months of
appropriate therapy including active participation in a non-operative therapy
program including balance training.
(d). Prior to surgical intervention, the
patient and treating physician should identify functional operative goals and
the likelihood of achieving improved ability to perform activities of daily
living or work activities and the patient should agree to comply with the pre-
and post-operative treatment plan including home exercise. The provider should
be especially careful to make sure the patient understands the amount of
post-operative therapy required and the length of partial- and full-disability
expected post-operatively.
(e). If
injury is a sprain: Smoking may affect soft tissue healing through tissue
hypoxia. Patients should be strongly encouraged to stop smoking and be provided
with appropriate counseling by the physician.
(f). If injury is a fracture: Because smokers
have a higher risk of non-union and post-operative costs, it is recommended
that carriers cover a smoking cessation program peri-operatively. Physicians
may monitor smoking cessation with laboratory tests such as cotinine levels for
long-term cessation.
vii. Operative Treatment: Repair of fractures
or other acute pathology as necessary. Primary ligament ankle reconstruction
with possible tendon transplant.
viii. Post-operative Treatment
(a). An individualized rehabilitation program
based upon communication between the surgeon and the therapist using therapies
as outlined in Therapeutic Procedures, Non-operative. Treatment may include
short-term post surgical casting. In all cases, communication between the
physician and therapist is important to the timing of weight-bearing and
exercise progressions.
(i). There is some
evidence that more rapid recovery occurs with functional rehabilitation
compared to six weeks of immobilization in a cast.
(b). The surgical procedures and the
patient's individual results dictate the amount of time a patient has non
weight-bearing restrictions. Fractures usually require six to eight weeks while
tendon transfers may be six weeks. Other soft tissue repairs, such as the
Brostrom lateral ankle stabilization, may be as short as three weeks.
(c). Return to work and restrictions after
surgery may be made by an attending physician experienced in occupational
medicine in consultation with the surgeon or by the surgeon.
e. Calcaneal Fracture:
i. Description/Definition: Osseous
fragmentation/separation confirmed by diagnostic studies.
ii. Occupational Relationship: Usually occurs
by fall or crush injury.
iii.
Specific Physical Exam Findings: Pain with range of motion and palpation of
calcaneus. Inability to bear weight, mal-positioning of heel, possible
impingement of sural nerve.
iv.
Diagnostic Testing Procedures: Radiographs and CT scan to assess for
intra-articular involvement. Lumbar films and urinalysis are usually performed
to rule out lumbar crush fractures when the mechanism of injury is a fall from
a height.
v. Non-operative
Treatment Procedures:
(a). Initial Treatment:
Non weight-bearing six to eight weeks, followed by weight-bearing cast at
physician's discretion and active therapy with or without passive
therapy.
(b). Medications such as
analgesics and anti-inflammatories may be helpful. Refer to medication
discussions in Medications and Medical Management.
(c). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management.
(d). Refer to comments related to
osteoporosis in Therapeutic Procedures, Non-operative, Osteoporosis
Management.
(e). Smoking may affect
fracture healing. Patients should be strongly encouraged to stop smoking and be
provided with appropriate counseling by the physician.
(f). Return to work with appropriate
restrictions should be considered early in the course of treatment. Refer to
Return to Work.
(g). Other
therapies in Therapeutic Procedures, Non-operative may be employed in
individual cases.
vi.
Surgical Indications/Considerations: Displacement of fragments, joint
depression, intra-articular involvement, mal-position of heel. Sanders Types II
and III are generally repaired surgically. However, the need for surgery will
depend on the individual case. Relative contraindications: smoking, diabetes,
or immunosuppressive disease.
(a). Because
smokers have a higher risk of non-union and post-operative costs, it is
recommended that carriers cover a smoking cessation program peri-operatively.
Physicians may monitor smoking cessation with laboratory tests such as cotinine
levels for long-term cessation.
vii. Operative Procedures: Open reduction
internal fixation. Subtalar fusion may be necessary in some cases when the
calcaneus is extremely comminuted. External fixation has been used when the
skin condition is poor.
(a). Complications
may include wound infections requiring skin graft.
viii. Post-operative Treatment:
(a). An individualized rehabilitation program
based upon communication between the surgeon and the therapist using the
therapies as outlined in Section F, Therapeutic Procedures, Non-operative. In
all cases, communication between the physician and therapist is important to
the timing of weight-bearing and exercise progressions.
(b). The patient is usually non
weight-bearing for six to eight weeks followed by weight-bearing for
approximately six to eight weeks at physician's discretion.
(c). Treatment may include the following:
restricted weight-bearing, bracing, active therapy with or without passive
therapy.
(d). Return to work and
restrictions after surgery may be made by an attending physician experienced in
occupational medicine in consultation with the surgeon or by the surgeon.
f. Chondral
and Osteochondral Defects:
i.
Description/Definition: Cartilage or cartilage and bone defect of the talar
surface. May be associated with ankle sprain or other injuries.
ii. Occupational Relationship: Usually caused
by a traumatic ankle injury.
iii.
Specific Physical Exam Findings: Ankle effusion, pain in joint and with
walking.
iv. Diagnostic Testing
Procedures: MRI may show bone bruising, osteochondral lesion, or possibly
articular cartilage injury. Radiographs, contrast radiography, CT may also be
used.
v. Non-Operative Treatment
Procedures:
(a). Initial Treatment: Acute
injuries may require immobilization followed by active therapy with or without
passive therapy.
(b). Medications
such as analgesics and anti-inflammatories may be helpful. Refer to medication
discussions in Medications and Medical Management.
(c). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management.
(d). Benefits may be achieved through
therapeutic rehabilitation and rehabilitation interventions. They should
include range-of-motion (ROM), active therapies, and a home exercise program.
Active therapies include, proprioception training, restoring normal joint
mechanics, and clearing dysfunctions from adjacent structures. Passive as well
as active therapies may be used for control of pain and swelling. Therapy
should progress to strengthening and an independent home exercise program
targeted to further improve ROM, strength, and normal joint mechanics
influenced by distal and proximal structures. Refer to Therapeutic Procedures,
Non-operative.
(i). Passive modalities are
most effective as adjunctive treatments to improve the results of active
treatment. They may be used as found in Therapeutic Procedures,
Non-operative.
(e).
Return to work with appropriate restrictions should be considered early in the
course of treatment. Refer to Return to Work.
(f). Other therapies in Therapeutic
Procedures, Non-operative may be employed in individual cases.
vi. Surgical
Indications/Considerations
(a). Functional
deficits not responsive to conservative therapy. Identification of an
osteochondral lesion by diagnostic testing procedures should be done to
determine the size of the lesion and stability of the joint.
(b). Microfracture is the initial treatment
unless there are other anatomic variants such as a cyst under the
bone.
(c). Osteochondral Autograft
Transfer System (OATS) may be effective in patients without other areas of
osteoarthritis, a BMI of less than 35 and a failed microfracture. This
procedure may be indicated when functional deficits interfere with activities
of daily living and/or job duties 6 to 12 weeks after a failed microfracture
with active patient participation in non-operative therapy. This procedure is
only appropriate in a small subset of patients..
(d). Autologous cartilage cell implant is not
FDA approved for the ankle and therefore not recommended.
(e). Prior to surgical intervention, the
patient and treating physician should identify functional operative goals and
the likelihood of achieving improved ability to perform activities of daily
living or work activities and the patient should agree to comply with the pre-
and post-operative treatment plan including home exercise. The provider should
be especially careful to make sure the patient understands the amount of
post-operative therapy required and the length of partial- and full-disability
expected post-operatively.
(f).
Smoking may affect tissue healing through tissue hypoxia. Patients should be
strongly encouraged to stop smoking and be provided with appropriate counseling
by the physician.
vii.
Operative Procedures: Arthroscopy with debridement or shaving of cartilage,
microfracture, mosiacplasty, fixation of loose osteochondral
fragments.
viii. Post-operative
Treatment
(a). An individualized
rehabilitation program based upon communication between the surgeon and the
therapist and using therapies as outlined in Therapeutic Procedures,
Non-operative. In all cases, communication between the physician and therapist
is important to the timing of weight-bearing and exercise
progressions.
(b). Treatment may
include the following: restricted weight-bearing, bracing, active therapy with
or without passive therapy.
(c).
Return to work and restrictions after surgery may be made by an attending
physician experienced in occupational medicine in consultation with the surgeon
or by the surgeon.
g. Heel Spur Syndrome/Plantar Fasciitis:
i. Description: Pain along the inferior
aspect of the heel at the calcaneal attachment of the plantar fascia and/or
along the course of the plantar fascia.
ii. Occupational Relationship: Condition may
be exacerbated by prolonged standing or walking on hard surfaces. Acute injury
may be caused by trauma. This may include jumping from a height or
hyperextension of the forefoot upon the rear foot.
iii. Specific Physical Exam Findings: Pain
with palpation at the inferior attachment of the plantar fascia to the os
calcis may be associated with calcaneal spur. Gastrocnemius tightness may be
tested with the Silfverskiold test. The foot is dorsiflexed with the knee
extended and then with the knee flexed. The test for gastrocnemius tightness is
considered positive if dorsiflexion is greater with the knee flexed than with
the knee extended.
iv. Diagnostic
Testing Procedures: Standard radiographs to rule out fracture, identify spur
after conservative therapy. Bone scans and/or MRI may be used to rule out
stress fractures in chronic cases.
v. Non-operative Treatment Procedures:
(a). Initial Treatment: This condition
usually responds to conservative management consisting of eccentric exercise of
the gastrocnemius, plantar fascial stretching, taping, soft-tissue
mobilization, night splints, and orthotics. Therapy may include passive
therapy, taping, and injection therapy.
(b). Shock absorbing shoe inserts may prevent
back and lower extremity problems in some work settings.
(c). Medications such as analgesics and
anti-inflammatories may be helpful. Refer to medication discussions in
Medications and Medical Management.
(d). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management.
(e). Steroid injections may decrease
inflammation and allow the therapist to progress with functional exercise and
range of motion. Steroid injections under significant pressure should be
avoided as the needle may be penetrating the tendon and injection into the
tendon can cause possible tendon breakdown, tendon degeneration, or rupture.
Injections should be minimized for patients under 30 years of age.
(i). Time to Produce Effect: One
injection.
(ii). Maximum Duration:
Three injections in one year spaced at least four to eight weeks
apart.
(iii). Steroid injections
should be used cautiously in diabetic patients. Diabetic patients should be
reminded to check their blood glucose levels at least daily for two weeks after
injections.
(f). Return
to work with appropriate restrictions should be considered early in the course
of treatment. Refer to Return to Work.
(g). After four months of failed therapy,
Extracorporeal Shock Wave Therapy (ESWT) trial may be considered prior to
surgery. Refer to Therapeutic Procedures, Non-operative.
(h). Other therapies in Therapeutic
Procedures, Non-operative may be employed in individual cases.
vi. Surgical
Indications/Considerations:
(a). Surgery is
employed only after failure of at least four to six months of active patient
participation in non-operative treatment.
(b). Indications for a gastrocnemius
recession include a positive Silfverskiold test. This procedure does not weaken
the arch as may occur with a plantar fascial procedure, however, there is a
paucity of literature on this procedure.
(c). Prior to surgical intervention, the
patient and treating physician should identify functional operative goals and
the likelihood of achieving improved ability to perform activities of daily
living or work activities and the patient should agree to comply with the pre-
and post-operative treatment plan including home exercise. The provider should
be especially careful to make sure the patient understands the amount of
post-operative therapy required and the length of partial- and full-disability
expected post-operatively.
(d).
Smoking may affect soft tissue healing through tissue hypoxia. Patients should
be strongly encouraged to stop smoking and be provided with appropriate
counseling by the physician.
vii. Operative Treatment Procedures: Plantar
fascial release with or without calcaneal spur removal, endoscopic or open
gastrocnemius recession.
viii.
Post-operative Treatment
(a). An
individualized rehabilitation program based upon communication between the
surgeon and the therapist using therapies as outlined in Therapeutic
Procedures, Non-operative.
(b).
Treatment may include the following: restricted weight-bearing, bracing, active
therapy with or without passive therapy. Usually non weight-bearing for 7 to 10
days followed by weight-bearing cast or shoe for four weeks; however, depending
on the procedure some patients may be restricted from weight-bearing for four
to six weeks.
(c). Return to work
and restrictions after surgery may be made by an attending physician
experienced in occupational medicine in consultation with the surgeon or by the
surgeon.
h.
Metatarsal-Phalangeal, Tarsal-Metatarsal and Interphalangeal Joint Arthropathy:
i. Description/Definition: Internal
derangement of joint.
ii.
Occupational Relationship: Jamming, contusion, crush injury, repetitive impact,
or post-traumatic arthrosis.
iii.
Specific Physical Exam Findings. Pain with palpation and ROM of joint,
effusion. The piano key test may be used, where the examiner stabilizes the
heel with one hand and presses down on the distal head of the metatarsals,
assessing for pain proximally.
iv.
Diagnostic Testing Procedures. Radiographs, diagnostic joint injection, CT,
MRI.
v. Non-operative Treatment
Procedures
(a). Medications such as
analgesics and anti-inflammatories may be helpful. Refer to medication
discussions in Medications and Medical Management.
(b). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management.
(c). Benefits may be achieved through
therapeutic rehabilitation and rehabilitation interventions. They should
include range-of-motion (ROM), active therapies, and a home exercise program.
Active therapies include, proprioception training, restoring normal joint
mechanics, and clearing dysfunctions from adjacent structures. Passive as well
as active therapies may be used for control of pain and swelling. Orthotics and
iontophoresis are usually included. A carbon fiber Morton extension may be
useful. Therapy should progress to strengthening and an independent home
exercise program targeted to further improve ROM, strength, and normal joint
mechanics influenced by distal and proximal structures. Refer to Therapeutic
Procedures, Non-operative.
(i). Passive
modalities are most effective as adjunctive treatments to improve the results
of active treatment. They may be used as found in Therapeutic Procedures,
Non-operative.
(d).
Steroid injections may decrease inflammation and allow the therapist to
progress with functional exercise and range of motion. Steroid injections under
significant pressure should be avoided as the needle may be penetrating the
tendon and injection into the tendon can cause possible tendon breakdown,
tendon degeneration, or rupture. Injections should be minimized for patients
under 30 years of age.
(i). Time to Produce
Effect: One injection.
(ii).
Maximum Duration: Three injections in one year spaced at least four to eight
weeks apart.
(iii). Steroid
injections should be used cautiously in diabetic patients. Diabetic patients
should be reminded to check their blood glucose levels at least daily for two
weeks after injections.
(e). Return to work with appropriate
restrictions should be considered early in the course of treatment. Refer to
Return to Work.
(f). Other
therapies in Therapeutic Procedures, Non-operative may be employed in
individual cases.
vi.
Surgical Indications/Considerations
(a).
Pain, unresponsive to conservative care and interfering with activities of
daily living.
(b). First metatarsal
arthritis or avascular necrosis can interfere with function and gait.
(c). Prior to surgical intervention, the
patient and treating physician should identify functional operative goals and
the likelihood of achieving improved ability to perform activities of daily
living or work activities and the patient should agree to comply with the pre-
and post-operative treatment plan including home exercise. The provider should
be especially careful to make sure the patient understands the amount of
post-operative therapy required and the length of partial- and full-disability
expected post-operatively.
(d).
Smoking may affect soft tissue healing through tissue hypoxia. Patients should
be strongly encouraged to stop smoking and be provided with appropriate
counseling by the physician.
vii. Operative Procedures: if debridement of
the arthritic joint and other conservative treatment is unsuccessful in
correcting gait and walking tolerance, other procedures may be considered.
Other procedures include: fusion of first metatarsal-phalangeal joint,
chilectomy, osteotomies, Keller arthroplasty and soft tissue procedures.
(a). There is some evidence that the first
metatarsal-phalangeal joint arthritis is better treated with arthrodesis than
arthroplasty for pain and functional improvement. Therefore, total joint
arthroplasties are not recommended for any metatarsal-phalangeal joints due to
less successful outcomes than fusions. There may be an exception for first and
second metatarsal-phalangeal joint arthroplasties when a patient is older than
60, has low activity levels, and cannot tolerate non weight-bearing for
prolonged periods or is at high risk for non-union.
(b). Metallic hemi-arthroplasties are still
considered experimental as long-term outcomes remain unknown in comparison to
arthrodesis, and there is a significant incidence of subsidence. Therefore,
these are not recommended at this time.
viii. Post-Operative Treatment
(a). An individualized rehabilitation program
based upon communication between the surgeon and the therapist using therapies
as outlined in Therapeutic Procedures, Non-operative. In all cases,
communication between the physician and therapist is important to the timing of
weight-bearing and exercise progressions.
(b). For fusions and osteotomies, reduced
weight-bearing and the use of special shoes will be necessary for at least ix
weeks post operative. For other procedures early range-of-motion, bracing,
and/or orthotics. Treatment usually also includes other active therapy with or
without passive therapy.
(c).
Return to work and restrictions after surgery may be made by an attending
physician experienced in occupational medicine in consultation with the surgeon
or by the surgeon.
i. Midfoot (Lisfranc) Fracture/Dislocation
i. Description/Definition:
Fracture/ligamentous disruption of the tarsal-metatarsal joints, i.e.,
metatarsal-cuneiform and metatarsal-cuboid bones.
ii. Occupational Relationship: Usually occurs
from a fall, crush, axial load with a plantar flexed foot, or abductory force
on the forefoot.
iii. Specific
Physical Exam Findings. Pain and swelling at the Lisfranc joint, first and/or
second metatarsal cuneiform articulation, palpable dorsal dislocation, pain on
forced abduction.
(a). Dislocation may not
always be apparent. Pronation and supination of the forefoot with the calcaneus
fixed in the examiners opposite hand may elicit pain in a Lisfranc injury,
distinguishing it from an ankle sprain, in which this maneuver is expected to
be painless. The piano key test may be used, where the examiner stabilizes the
heel with one hand and presses down on the distal head of the metatarsal,
assessing for pain proximally. The dorsalis pedis artery crosses the second
metatarsal and may be disrupted. Therefore, the dorsalis pedis pulse and
capillary filling should be assessed.
iv. Diagnostic Testing Procedures: X-rays, CT
scans, MRI, mid-foot stress x-rays.
v. Non-operative Treatment Procedures:
(a). Initial Treatment: If minimal or no
displacement then casting, non weight-bearing six to eight weeks. Orthoses may
be used later.
(b). Medications
such as analgesics and anti-inflammatories may be helpful. Refer to medication
discussions in Medications and Medical Management.
(c). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management.
(d). Refer to comments related to
osteoporosis in Therapeutic Procedures, Non-operative, Osteoporosis
Management.
(e). Smoking may affect
fracture healing. Patients should be strongly encouraged to stop smoking and be
provided with appropriate counseling by the physician.
(f). Return to work with appropriate
restrictions should be considered early in the course of treatment. Refer to
Return to Work.
(g). Other
therapies in Therapeutic Procedures, Non-operative may be employed in
individual cases.
vi.
Surgical Indications/Considerations: Displacement of fragments or
intra-articular fracture. Most Lisfranc fracture/dislocations are treated
surgically.
(a). Because smokers have a higher
risk of non-union and post-operative costs, it is recommended that carriers
cover a smoking cessation program peri-operatively. Physicians may monitor
smoking cessation with laboratory tests such as cotinine levels for long-term
cessation.
vii.
Operative Procedures: Open reduction internal fixation with possible removal of
hardware at approximately three to six months, pending healing status.

(b). The patient is usually in cast or
fracture walker for six to eight weeks non weight-bearing. Orthoses may be
indicated after healing.
(c).
Treatment may include the following: restricted weight-bearing, bracing, active
therapy with or without passive therapy.
(d). Return to work and restrictions after
surgery may be made by an attending physician experienced in occupational
medicine in consultation with the surgeon or by the surgeon.

foot and ankle, General recommendations can be found in Tendonopathy of the
Knee.
2. Knee
a. Aggravated Osteoarthritis
i. Description/Definition: Swelling and/or
pain in a joint due to an aggravating activity in a patient with pre-existing
degenerative change in a joint. Age greater than 50 and morning stiffness
lasting less than 30 minutes are frequently associated. The lifetime risk for
symptomatic knee arthritis is probably around 45 percent and is higher among
obese persons.
ii. Occupational
Relationship: The provider must establish the occupational relationship by
establishing a change in the patient's baseline condition and a relationship to
work activities including but not limited to physical activities such as
repetitive kneeling or crawling, squatting and climbing, or heavy lifting.
(a). Other causative factors to consider -
Previous meniscus or ACL damage may predispose a joint to degenerative changes.
In order to entertain previous trauma as a cause, the patient should have
medical documentation of the following: menisectomy; hemarthrosis at the time
of the original injury; or evidence of MRI or arthroscopic meniscus or ACL
damage. The prior injury should have been at least two years from the
presentation for the new complaints and there should be a significant increase
of pathology on the affected side in comparison to the original imaging or
operative reports and/or the opposite un-injured side or extremity.
(b). Body mass index (BMI) of 25 or greater
is a significant risk factor for eventual knee replacement.
iii. Specific Physical Exam
Findings: Increased pain and/or swelling in a joint with joint line tenderness;
joint crepitus; and/or joint deformity.
iv. Diagnostic Testing Procedures:
Radiographs, The Kellgren-Lawrence Scale is the standard radiographic scale for
knee osteoarthritis. It is based on the development of osteophytes, on bone
sclerosis, and on joint space narrowing. The degree of joint space narrowing
may not predict disability.
(a). Grade 1:
doubtful narrowing of joint space, and possible osteophytic lipping.
(b). Grade 2: definite osteophytes, definite
narrowing of joint space.
(c).
Grade 3: moderate multiple osteophytes, definite narrowing of joint space, some
sclerosis and possible deformity of bone contour.
(d). Grade 4: large osteophytes, marked
narrowing of joint space, severe sclerosis and definite deformity of bone
contour.
(e). MRI to rule out
degenerative menisci tears. MRI may identify bone marrow lesions which are
correlated with knee pain. These lesions may reflect increased water, blood, or
other fluid inside bone and may contribute to the causal pathway of pain. These
are incidental findings and should not be used to determine a final diagnosis
nor make decisions regarding surgery.
v. Non-Operative Treatment Procedures
(a). Medications such as analgesics and
anti-inflammatories may be helpful. Refer to medication discussions in
Medications and Medical Management.
(b). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management. There is good evidence for
self-management using weight loss, exercise, pacing of activities, unloading
the joint with braces, insoles and possibly taping, and medications as needed.
Patients should be encouraged to perform aerobic activity such as walking or
biking. However, activities such as ladders, stairs and kneeling may be
restricted.
(c). Benefits may be
achieved through therapeutic rehabilitation and rehabilitation interventions.
They should include range-of-motion (ROM), active therapies, and a home
exercise program. Active therapies include, proprioception training, restoring
normal joint mechanics, and clearing dysfunctions from distal to proximal
structures. Passive as well as active therapies may be used for control of pain
and swelling. Therapy should progress to strengthening and an independent home
exercise program targeted to further improve ROM, strength, and normal joint
mechanics influenced by structures distal and proximal to the knee. Bracing may
be appropriate in some instances. Refer to Therapeutic Procedures,
Non-operative. There is good evidence that there is a small functional
advantage for patients involved in exercise with physical therapy supervision
over home exercise.
(i). There is some
evidence that active physical therapy improves knee function more effectively
than medication alone.
(ii).
Aquatic therapy may be used as a type of active intervention when land-based
therapy is not well-tolerated.
(iii). Passive modalities are most effective
as adjunctive treatments to improve the results of active treatment. They may
be used as found in Therapeutic Procedures, Non-operative. There is some
evidence that ice massage can improve ROM, strengthening of the knee and
function. Ice can be used with proper instruction at home or under supervision
for up to 20 minute periods 3 times per week or more frequently.
(d). Therapeutic Injections - both
steroids and viscosupplementation may be used.
(i). There is good evidence that
intra-articular corticosteroid injection is more effective than placebo in
reducing pain from osteoarthritis. Optimum dosage is not known.
(ii). Steroid injections may decrease
inflammation and allow the therapist to progress with functional exercise and
ROM.
[a]. Time to Produce Effect: One
injection.
[b]. Maximum Duration:
Three injections in one year at least four to eight weeks apart.
(iii). Steroid
injections should be used cautiously in diabetic patients. Diabetic patients
should be reminded to check their blood glucose levels at least daily for two
weeks after injections.
(iv).
Viscosupplementation appears to have a longer lasting effect than
intra-articular corticosteroids, however, the overall effect varies depending
on the timing and the effect studied. Refer to Therapeutic Procedures.
(e). Return to work with
appropriate restrictions should be considered early in the course of treatment.
Refer to Return to Work.
(f). Other
therapies in Therapeutic Procedures, Non-operative may be employed in
individual cases.
(g). Bracing such
as knee immobilizer or hinge brace may be used for acute ACL injuries.
vi. Surgical
Indications/Considerations.
(a). Arthroscopic
Debridement and/or Lavage. There is good evidence from a randomized controlled
trial that arthroscopic debridement alone provides no benefit over recommended
therapy for patients with uncomplicated Grade 2 or higher arthritis. The
comparison recommended treatment in the study followed the American College of
Rheumatology guidelines which includes: patient education, and supervised
therapy with a home program, instruction on ADLs, stepwise use of analgesics
and hyaluronic acid injections if desired. Complicated arthritic patients
excluded from the study included patients who required other forms of
intervention due to the following associated conditions: large meniscal bucket
handle tears, inflammatory or infectious arthritis, more than 5 degrees of
varus or valgus deformity, previous major knee trauma, or Grade 4 arthritis in
two or more compartments.
(i). Therefore,
arthroscopic debridement and/or lavage are not recommended for patients with
arthritic findings and continual pain and functional deficits unless there is
meniscal or cruciate pathology. Refer to the specific conditions in Specific
Lower Extremity Injury Diagnosis, Testing and Treatment, for specific
diagnostic recommendations.
(b). Osteotomy and joint replacement are
indicated when conservative treatment, including active participation in
non-operative treatment has failed to result in sufficient functional
improvement (Refer to Knee Arthroplasty, and Osteotomy). Tibial osteotomy is a
choice for younger patients with unicompartmental disease who have failed
conservative therapy.
(c). In cases
where surgery is contraindicated due to obesity, it may be appropriate to
recommend a weight loss program if the patient is unsuccessful losing weight on
their own. Coverage for weight loss would continue only for motivated patients
who have demonstrated continual progress with weight loss.
(d). Prior to surgical intervention, the
patient and treating physician should identify functional operative goals and
the likelihood of achieving improved ability to perform activities of daily
living or work activities and the patient should agree to comply with the pre-
and post-operative treatment plan including home exercise. The provider should
be especially careful to make sure the patient understands the amount of
post-operative therapy required and the length of partial- and full-disability
expected post-operatively.
(e).
Because smokers have a higher risk of non-union and post-operative costs, it is
recommended that carriers cover a smoking cessation program peri-operatively.
Physicians may monitor smoking cessation with laboratory tests such as cotinine
levels for long-term cessation.
vii. Operative Procedures: Total or
compartmental joint replacement, and osteotomy.
(a). Free-floating interpositional
unicompartmental replacement is not recommended for any patients due to high
revision rate at two years and less than optimal pain relief.
viii. Post-Operative Treatment
(a). An individualized rehabilitation program
based upon communication between the surgeon and therapist and using the
treatments found in Therapeutic Procedures, Non-operative. In all cases,
communication between the physician and therapist is important to the timing of
weight-bearing and exercise progressions.
(b). Refer also to Knee Arthroplasty, or
Osteotomy as appropriate.
(c).
Return to work and restrictions after surgery may be made by an attending
physician experienced in occupational medicine in consultation with the surgeon
or by the surgeon.
b. Anterior Cruciate Ligament (ACL) Injury
i. Description/Definition: Rupture or partial
rupture of the anterior cruciate ligament; may be associated with other
internal derangement of the knee.
ii. Occupational Relationship: May be caused
by virtually any traumatic force to the knee but most often caused by a
twisting or a hyperextension force, with a valgus stress. The foot is usually
planted and the patient frequently experiences a "popping" feeling.
iii. Specific Physical Exam Findings:
Findings on physical exam include effusion or hemarthrosis, instability,
positive Lachman's test, positive pivot shift test, and positive anterior
drawer test.
iv. Diagnostic Testing
Procedures: MRI. Radiographs may show avulsed portion of tibial spine but this
is a rare finding.
v. Non-operative
Treatment Procedures:
(a). Initial Treatment:
Acute injuries may require immobilization followed by active therapy with or
without passive therapy.
(b).
Medications such as analgesics and anti-inflammatories may be helpful. Refer to
Medications and Medical Management.
(c). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management.
(d). Benefits may be achieved through
therapeutic rehabilitation and rehabilitation interventions. They should
include range-of-motion (ROM), active therapies, and a home exercise program.
Active therapies include proprioception training, restoring normal joint
mechanics, and clearing dysfunctions from distal and proximal structures
bracing may be beneficial. Passive as well as active therapies may be used for
control of pain and swelling. Therapy should progress to strengthening and an
independent home exercise program targeted to further improve ROM, strength,
and normal joint mechanics influenced by structures distal and proximal to the
knee (Refer to Therapeutic Procedures, Non-operative). Passive modalities are
most effective as adjunctive treatments to improve the results of active
treatment. They may be used as found in Therapeutic Procedures, Non-operative.
(i). There is no evidence that any particular
exercise regime is better for ACL injuries in combination with collateral or
meniscus injuries. There is no evidence that knee bracing for non operated ACL
improves outcomes although patients may feel that they have greater stability.
Non surgical treatment may provide acceptable results in some
patients.
(e). Return to
work with appropriate restrictions should be considered early in the course of
treatment. Refer to Return to Work.
(f). Other therapies in Therapeutic
Procedures, Non-operative may be employed in individual cases.
iv. Surgical
Indications/Considerations: any individual with complaints of recurrent
instability interfering with function and physical findings with imaging
consistent with an ACL injury.
(a). Prior to
surgical intervention, the patient and treating physician should identify
functional operative goals and the likelihood of achieving improved ability to
perform activities of daily living or work activities and the patient should
agree to comply with the pre- and post-operative treatment plan including home
exercise. The provider should be especially careful to make sure the patient
understands the amount of post-operative therapy required and the length of
partial- and full-disability expected post-operatively.
(b). Smoking may affect soft tissue healing
through tissue hypoxia. Patients should be strongly encouraged to stop smoking
and be provided with appropriate counseling by the physician.
v. Operative Procedures
(a). Diagnostic/surgical arthroscopy followed
by ACL reconstruction using autograft or allograft. If meniscus repair is
performed, an ACL repair should be performed concurrently.
(b). Patients tend to have more pain
associated with patellar grafts while patients with hamstring replacement seem
to have an easier rehabilitation. Choice of graft is made by the surgeon and
patient on an individual basis.
vi. Post-Operative Treatment
(a). An individualized rehabilitation program
based upon communication between the surgeon and the therapist and using
therapies as outlined in Therapeutic Procedures, Non-operative.
(b). Treatment may include the following:
active therapy with or without passive therapy and bracing. Early active
extension does not cause increased laxity at two years.
(c). Return to work and restrictions after
surgery may be made by an attending physician experienced in occupational
medicine in consultation with the surgeon or by the surgeon.
c. Bursitis of the
Lower Extremity
i. Description/Definition:
Inflammation of bursa tissue. Bursitis can be precipitated by tendonitis, bone
spurs, foreign bodies, gout, arthritis, muscle tears, or infection.
ii. Occupational Relationship: Soft tissue
trauma, contusion, or physical activities of the job such as sustained direct
compression force, or other repetitive forceful activities affecting the
knee.
iii. Specific Physical Exam
Findings: Palpable, tender and enlarged bursa, decreased ROM, warmth. The
patient may have increased pain with ROM.
iv. Diagnostic Testing Procedures: Lab work
may be done to rule out inflammatory disease. Bursal fluid aspiration with
testing for connective tissue, rheumatic disease, and infection may be
necessary. Radiographs, CT, MRI are rarely indicated.
v. Non-operative Treatment Procedures
(a). Initial Treatment:
Diagnostic/therapeutic aspiration, ice, therapeutic injection, treatment of an
underlying infection, if present. Aspirations may be repeated as clinically
indicated.
(b). Medications such as
analgesics and anti-inflammatories may be helpful. Refer to medication
discussions in Medications and Medical Management.
(c). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management.
(d). Benefits may be achieved through
therapeutic rehabilitation and rehabilitation interventions. They should
include range-of-motion (ROM), active therapies, including a home exercise
program. Active therapies include, proprioception training, restoring normal
joint mechanics, and clearing dysfunctions from distal and proximal joints.
Passive as well as active therapies may be used for control of pain and
swelling. Therapy should progress to strengthening and an independent home
exercise program targeted to further improve ROM, strength, and normal joint
mechanics influenced by structures distal and proximal to the knee. Refer to
Therapeutic Procedures, Non-operative.
(i).
Passive modalities are most effective as adjunctive treatments to improve the
results of active treatment. They may be used as found as adjunctive in
Therapeutic Procedures, Non-operative.
(e). Steroid Injections. Steroid injections
may decrease inflammation and allow the therapist to progress with functional
exercise and ROM.
(i). Time to Produce
Effect: One injection.
(ii).
Maximum Duration: Three injections in one year spaced at least four to eight
weeks apart.
(iii). Steroid
injections should be used cautiously in diabetic patients. Diabetic patients
should be reminded to check their blood glucose levels at least daily for two
weeks after injections.
(f). Return to work with appropriate
restrictions should be considered early in the course of treatment. Refer to
Return to Work.
(g). Other
therapies in Therapeutic Procedures, Non-operative may be employed in
individual cases.
vi.
Surgical indications/Considerations:
(a).
Failure of conservative therapy.
(b). Prior to surgical intervention, the
patient and treating physician should identify functional operative goals and
the likelihood of achieving improved ability to perform activities of daily
living or work activities and the patient should agree to comply with the pre-
and post-operative treatment plan including home exercise. The provider should
be especially careful to make sure the patient understands the amount of
post-operative therapy required and the length of partial- and full-disability
expected post-operatively.
(c).
Smoking may affect soft tissue healing through tissue hypoxia. Patients should
be strongly encouraged to stop smoking and be provided with appropriate
counseling by the physician.
vii. Operative Procedures: Surgical excision
of the bursa.
viii. Post-operative
Treatment
(a). An individualized
rehabilitation program based upon communication between the surgeon and the
therapist and using the therapies as outlined in Therapeutic Procedures,
Non-operative.
(b). Return to work
and restrictions after surgery may be made by an attending physician
experienced in occupational medicine in consultation with the surgeon or by the
surgeon.
d.
Chondral and Osteochondral Defects
i.
Description/Definition: Cartilage or cartilage and bone defect at the articular
surface of a joint. Deficits may be identified in up to 60 percent of
arthroscopies; however, only around 30 percent of these lesions are isolated
deficits and even fewer are Grade III or IV deficits which might qualify for
cartilage grafts.
(a). Defects in cartilage
and bone are common at the femoral condyles and patella. The Outerbridge
classification grades these defects according to their size and depth.
(i). Grade 0: normal cartilage.
(ii). Grade I: softening and swelling of
cartilage.
(iii). Grade II:
partial-thickness defects with surface fissures that do not exceed 1.5 cm in
diameter and do not reach subchondral bone.
(iv). Grade III: fissuring that reaches
subchondral bone in an area with a diameter greater than 1.5 cm.
(v). Grade IV: exposed subchondral
bone.
ii.
Occupational Relationship: Typically caused by a traumatic knee injury.
Chondral deficits can also be present secondary to osteoarthritis.
iii. Specific Physical Exam Findings: Knee
effusion, joint line tenderness.
iv. Diagnostic Testing Procedures: MRI may
show bone bruising, osteochondral lesion, or possibly articular cartilage
injury. Radiographs, contrast radiography, CT may also be used. Diagnostic
arthroscopy may be performed when surgical indications as stated in Section VI
are met.
v. Non-Operative Treatment
Procedures:
(a). Initial Treatment:
Non-operative treatment may be indicated for chondral lesions associated with
degenerative changes, refer to aggravated osteoarthritis; other knee lesions
not requiring surgery (refer to Specific Diagnosis); and/or non-displaced
stable lesions. Acute injuries may require immobilization followed by active
therapy with or without passive therapy.
(b). Medications such as analgesics and
anti-inflammatories may be helpful. Refer to medication discussions in
Medications and Medical Management.
(c). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management.
(d). Benefits may be achieved through
therapeutic rehabilitation and rehabilitation interventions. They should
include range-of-motion (ROM), active therapies, and a home exercise program.
Active therapies include, proprioception training, restoring normal joint
mechanics, and clearing dysfunctions from distal and proximal structures.
Passive as well as active therapies may be used for control of pain and
swelling. Therapy should progress to strengthening and an independent home
exercise program targeted to further improve ROM, strength, and normal joint
mechanics influenced by structures distal and proximal to the knee. Refer to
Therapeutic Procedures, Non-operative.
(i).
Passive modalities are most effective as adjunctive treatments to improve the
results of active treatment. They may be used as found in Therapeutic
Procedures, Non-operative.
(e). Return to work with appropriate
restrictions should be considered early in the course of treatment. Refer to
Return to Work.
(f). Other
therapies in Therapeutic Procedures, Non-operative may be employed in
individual cases.
vi.
Surgical Indications/Considerations: Surgery for isolated chondral defects may
be indicated when functional deficits interfere with activities of daily living
and/or job duties after 6 to 12 weeks of active patient participation in
non-operative therapy. Identification of the lesion should have been
accomplished by diagnostic testing procedures which describe the size of the
lesion and stability of the joint. If a lesion is detached or has fluid
underlying the bone on MRI, surgery may be necessary before a trial of
conservative therapy is completed. Early surgery may consist of fixation or
microfracture.
(a). Microfractures: Normally
the first line of surgical treatment.
(i).
Indications: An isolated small full-thickness articular chondral defect with
normal joint space, when the patient has not recovered functionally after
active participation in therapy. Patients 45 or younger are likely to have
better results.
(b).
Osteochondral Autograft Transfer System (OATS)
(i). Indications: The knee must be stable
with intact ligaments and menisci, normal joint space and a large
full-thickness defect less than 3 square cm and 1 cm depth. They should be 45
or younger, with a BMI less than 35, and engaged in athletics and/or an equally
physically demanding occupation. Surgery may be indicated when functional
deficits interfere with activities of daily living and/or job duties after 6 to
12 weeks of active patient participation in non-operative therapy. This
procedure may be appropriate in a small subset of patients.
(c). Autologous chondrocyte
implantation (ACI): These procedures are technically difficult and require
specific physician expertise. Cartilage transplantation requires the harvesting
and growth of patients' cartilage cells in a highly specialized lab and incurs
significant laboratory charges. There is some evidence that transplants and
microfractures do not differ on long-term effects. There is some evidence that
autologous chrondrocyte implantation is not better than microfracture five
years after surgery in patients younger than 45 presenting with Grade III -IV
lesions. This procedure is controversial but may be appropriate in a small
subset of patients with physically rigorous employment or recreational
activities. It requires prior authorization.
(i). Indications: The area of the lesion
should be between 2 square cm and 10 square cm. The patient should have failed
four or more months of active participation in therapy and a microfracture,
abrasion, arthroplasty or drilling with sufficient healing time, which may be
from four months to over one year. The knee must be stable with intact
ligaments and meniscus, and normal joint space. Patients should be 45 or
younger, with a BMI less than 35, and engaged in athletics and/or an equally
physically demanding occupation.
(d). Contraindications: General
contraindications for grafts and transplants are individuals with obesity,
inflammatory or osteoarthritis with multiple chondral defects, associated
ligamentous or meniscus pathology, or who are older than 55 years of
age.
(e). Prior to either graft or
implantation intervention the patient and treating physician should identify
functional operative goals and the likelihood of achieving improved ability to
perform activities of daily living or work activities and the patient should
agree to comply with the pre- and post-operative treatment plan including home
exercise. The provider should be especially careful to make sure the patient
understands the amount of post-operative therapy required and the length of
partial- and full-disability expected post-operatively.
(f). Smoking may affect soft tissue healing
through tissue hypoxia. Patients should be strongly encouraged to stop smoking
and be provided with appropriate counseling by the physician.
vii. Operative Procedures:
Arthroscopy with debridement or shaving of cartilage, microfracture, drilling,
abrasion arthroplasty, mosiacplasty or osteochondral autograft (OATS), fixation
of loose osteochondral fragments and autologous chondrocyte implantation (ACI).
(a). Radiofrequency treatment is not
recommended.
viii.
Post-Operative Treatment
(a). An
individualized rehabilitation program based upon communication between the
surgeon and the therapist and using therapies as outlined in Therapeutic
Procedures, Non-operative. In all cases, communication between the physician
and therapist is important to the timing of weight-bearing and exercise
progressions.
(b). Treatment may
include the following: restricted weight-bearing, bracing, active therapy with
or without passive therapy. Full weight-bearing usually occurs by or before 8
weeks.
(c). Continuous passive
motion may be used after chondral procedures.
(d). Return to work and restrictions after
surgery may be made by an attending physician experienced in occupational
medicine in consultation with the surgeon or by the surgeon. Return to
full-duty usually occurs by between four and six months.
(e). Collateral Ligament Pathology
(i). Description/Definition: Strain or tear
of medial or lateral collateral ligaments which provide some stabilization for
the knee.
(ii). Occupational
Relationship: Typically a result of forced abduction and external rotation to
an extended or slightly flexed knee.
(iii). Specific Physical Exam Findings:
Swelling or ecchymosis over the collateral ligaments and increased laxity or
pain with applied stress.
(iv).
Diagnostic Testing Procedures: X-rays to rule out fracture. Imaging is more
commonly ordered when internal derangement is suspected.
(v). Non-Operative Treatment Procedures
[a]. Initial Treatment: braces, ice, and
protected weight-bearing.
[b].
Medications such as analgesics and anti-inflammatories may be helpful. Refer to
medication discussions area in Medications and Medical Management.
[c]. Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management.
[d]. Benefits may be achieved through
therapeutic rehabilitation and rehabilitation interventions. They should
include range-of-motion (ROM), active therapies, and a home exercise program.
Active therapies include proprioception training, restoring normal joint
mechanics, and clearing dysfunctions from distal and proximal structures.
Bracing may be beneficial. Passive as well as active therapies may be used for
control of pain and swelling. Therapy should progress to strengthening and an
independent home exercise program targeted to further improve ROM, strength,
and normal joint mechanics influenced by structures distal and proximal to the
knee. Refer to Therapeutic Procedures, Non-operative.
[i]. Passive modalities are most effective as
adjunctive treatments to improve the results of active treatment. They may be
used as found in Therapeutic Procedures, Non-operative.
[e]. Return to work with appropriate
restrictions should be considered early in the course of treatment. Refer to
Return to Work.
[f]. Other
therapies in Therapeutic Procedures, Non-operative may be employed in
individual cases.
ix. Surgical Indications/Considerations:
Surgery is rarely necessary except when functional instability persists after
active participation in non-operative treatment or indications for surgery
exist due to other accompanying injuries.
(a). Prior to surgical intervention, the
patient and treating physician should identify functional operative goals and
the likelihood of achieving improved ability to perform activities of daily
living or work activities and the patient should agree to comply with the pre-
and post-operative treatment plan including home exercise. The provider should
be especially careful to make sure the patient understands the amount of
post-operative therapy required and the length of partial- and full-disability
expected post-operatively.
(b).
Smoking may affect soft tissue healing through tissue hypoxia. Patients should
be strongly encouraged to stop smoking and be provided with appropriate
counseling by the physician.
x. Operative Procedures: Surgical repair.
xi. Post-operative Treatment
(a). An individualized rehabilitation program
based upon communication between the surgeon and the therapist and using
procedures as outlined in Therapeutic Procedures, Non-Operative.
(b). Return to work and restrictions after
surgery may be made by an attending physician experienced in occupational
medicine in consultation with the surgeon or by the surgeon.
f. Meniscus Injury
i. Description/Definition - a tear,
disruption, or avulsion of medial or lateral meniscus tissue. Locking of the
knee or clicking is frequently reported. Patients may describe a popping,
tearing, or catching sensation followed by stiffness.
ii. Occupational Relationship - trauma to the
menisci from rotational shearing, torsion, and/or impact injuries while in a
flexed position.
iii. Specific
Physical Exam Findings: Joint line tenderness, Positive McMurray's test locked
joint, or occasionally, effusion. The presence of joint line tenderness has a
sensitivity of 85 percent and a specificity of 31 percent. The Apley's
compression test is also used.
iv.
Diagnostic Testing Procedures. Radiographs including standing
Posterior/Anterior (PA), lateral, tunnel, and skyline views. MRI is the
definitive imaging test. MRI is sensitive and specific for meniscal tear.
However, meniscal MRI is frequently abnormal in asymptomatic injuries. In one
study of volunteers without a history of knee pain, swelling, locking, giving
way, or any knee injury, 16 percent of the volunteers had MRI-evident meniscal
tears; among volunteers older than 45, 36 percent had MRI-evident meniscal
tears. Therefore, clinical correlation with history and physical exam findings
specific for meniscus injury is critically important.
(a). Providers planning treatment should
therefore consider the patient's complaints and presence of arthritis on MRI
carefully, knowing that not all meniscus tears in the middle aged and older
population are related to the patients' complaints of pain.
(b). MRI arthrograms are used to diagnose
recurrent meniscal tears particularly after previous surgery.
v. Non-operative Treatment
(a). Initial Treatment: ice, bracing, and
protected weight-bearing.
(b).
Medications such as analgesics and anti-inflammatories may be helpful. Refer to
medication discussions in Medications and Medical Management.
(c). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management.
(d). Benefits may be achieved through
therapeutic rehabilitation and rehabilitation interventions. They should
include range-of-motion (ROM), active therapies, and a home exercise program.
Active therapies include, proprioception training, restoring normal joint
mechanics, and clearing dysfunctions from distal and proximal structures.
Passive as well as active therapies may be used for control of pain and
swelling. Therapy should progress to strengthening and an independent home
exercise program targeted to further improve ROM, strength, and normal joint
mechanics influenced by structures distal and proximal to the knee. Refer to
Therapeutic Procedures, Non-operative.
(i).
Passive modalities are most effective as adjunctive treatments to improve the
results of active treatment. They may be used as found as adjunctive in
Therapeutic Procedures, Non-Operative.
(e). Return to work with appropriate
restrictions should be considered early in the course of treatment. Refer to
Return to Work.
(f). Other
therapies in Therapeutic Procedures, Non-operative may be employed in
individual cases.
vi.
Surgical Indications/Considerations: Locked or blocked knee precluding active
therapy; Isolated acute meniscus tear with appropriate physical exam findings;
Meniscus pathology combined with osteoarthritis in a patient with functional
deficits interfering with activities of daily living and/or job duties after 6
to 12 weeks of active patient participation in non-operative therapy.
(a). It is not clear that partial
meniscectomy for a chronic degenerative meniscal tear is beneficial. Middle
aged patients may do as well without arthroscopy and with therapy.
(b). Meniscal allograft should only be
performed on patients between 20 and 45 with an otherwise stable knee, previous
meniscectomy with 2/3 removed, lack of function despite active therapy, BMI
less than 35, and sufficient joint surface to support repair.
(c). Medial collagen meniscus implants are
considered experimental and not generally recommended. No studies have been
done to compare this procedure to medial meniscus repair. There is some
evidence to support the fact that collagen meniscal implant may slightly
improve function and decrease risk of reoperation in patients with previous
medial meniscal surgery. It remains unclear as to the extent that the procedure
may decrease future degenerative disease. The procedure can only be considered
for individuals with previous medial meniscal surgery and intact meniscus rim;
without lateral meniscus lesions or Grade 4 Outerbridge lesions; and who need
to return to heavy physical labor employment or demanding recreational
activities. A second concurring opinion from an orthopedic surgeon specializing
in knee surgery and prior authorization is required. Full weight-bearing is not
allowed for 6 weeks and most patients return to normal daily activity after
three months.
(d). Prior to
surgical intervention, the patient and treating physician should identify
functional operative goals and the likelihood of achieving improved ability to
perform activities of daily living or work activities and the patient should
agree to comply with the pre- and post-operative treatment plan including home
exercise. The provider should be especially careful to make sure the patient
understands the amount of post-operative therapy required and the length of
partial- and full-disability expected post-operatively.
(e). Smoking may affect soft tissue healing
through tissue hypoxia. Patients should be strongly encouraged to stop smoking
and be provided with appropriate counseling by the physician.
vii. Operative Treatment: Repair
of meniscus, partial or complete excision of meniscus or meniscus allograft or
implant. Debridement of the meniscus is not recommended in patients with severe
arthritis as it is unlikely to alleviate symptoms. Complete excision of
meniscus should only be performed when clearly indicated due to the long-term
risk of arthritis in these patients. Partial meniscectomy or meniscus repair is
preferred to total meniscectomy due to easier recovery, less instability, and
short-term functional gains.
viii.
Post-operative Treatment
(a). An
individualized rehabilitation program based upon communication between the
surgeon and the therapist using the treatments found in Therapeutic Procedures,
Non-operative.
(b). Treatment may
include the following: Passive therapy progressively moving toward active
therapy, bracing, cryotherapy and other treatments found in Therapeutic
procedures Non-Operative.
(c).
Return to work and restrictions after surgery may be made by an attending
physician experienced in occupational medicine in consultation with the surgeon
or by the surgeon.
g. Patellar Fracture
i. Description/Definition: Fracture of the
patella.
ii. Occupational
Relationship: Usually from a traumatic injury such as a fall or direct
blow
iii. Specific Physical Exam
Findings: Significant hemarthrosis/effusion usually present. Extension may be
limited and may indicate disruption of the extensor mechanism. It is essential
to rule out open fractures; therefore a thorough search for lacerations is
important.
iv. Diagnostic Testing
Procedures. Aspiration of the joint and injection of local anesthetic may aid
the diagnosis. A saline load injected in the joint can also help rule out an
open joint injury. Radiographs may be performed, including tangential (sunrise)
or axial views and x-ray of the opposite knee in many cases. CT or MRI is
rarely needed.
v. Non-Operative
Treatment Procedures
(a). Initial Treatment:
For non-displaced closed fractures, protected weight-bearing and splinting for
four to six weeks. Hinged knee braces can be used. When radiographs demonstrate
consolidation, active motion and strengthening exercise may begin.
(b). Medications such as analgesics and
anti-inflammatories may be helpful. Refer to medication discussions in
Medications and Medical Management.
(c). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management.
(d). Refer to comments related to
osteoporosis in Therapeutic Procedures, Non-operative, Osteoporosis
Management.
(e). Smoking may affect
fracture healing. Patients should be strongly encouraged to stop smoking and be
provided with appropriate counseling by the physician.
(f). Benefits may be achieved through
therapeutic rehabilitation and rehabilitation interventions, after boney union
has been achieved. They should include bracing then range-of-motion (ROM),
active therapies including proprioception training, restoring normal joint
mechanics, and clearing dysfunctions from adjacent structures, and a home
exercise program. Passive as well as active therapies may be used for control
of pain and swelling. Therapy should progress to strengthening and an
independent home exercise program targeted to further improve ROM, strength,
restoring normal joint mechanics, influenced by proximal and distal structures.
Therapy should include training on the use of adaptive equipment and home and
work site evaluations when appropriate. Bracing may be appropriate. Refer to
Therapeutic Procedures, Non-operative.
(i).
Passive modalities are most effective as adjunctive treatments to improve the
results of active treatment. They may be used as found as adjunctive in
Therapeutic Procedures, Non-operative.
(g). Return to work with appropriate
restrictions should be considered early in the course of treatment. Refer to
Return to Work.
(h). Other
therapies in Therapeutic Procedures. Non-operative may be employed in
individual cases.
vi.
Surgical Indications/Considerations: Open fractures require immediate
intervention and may need repeat debridement. Internal fixation is usually
required for comminuted or displaced fractures. Non-union may also require
surgery.
(a). Because smokers have a higher
risk of non-union and post-operative costs, it is recommended that insurers
cover a smoking cessation program peri-operatively. Physicians may monitor
smoking cessation with laboratory tests such as cotinine levels for long-term
cessation.
vii.
Operative Procedures: internal fixation; partial patellectomy or total
patellectomy. Total patellectomy results in instability with running or stairs
and significant loss of extensor strength. Therefore, this is usually a salvage
procedure.
viii. Post-Operative
Treatment
(a). An individualized
rehabilitation program based upon communication between the surgeon and the
therapist and using therapies as outlined in Therapeutic Procedures,
Non-operative. In all cases, communication between the physician and therapist
is important to the timing of weight-bearing and exercise progressions.
Continuous passive motion may be used post operatively.
(b). Treatment may include protected
weight-bearing and active therapy with or without passive therapy for early
range of motion if joint involvement.
(c). Return to work and restrictions after
surgery may be made by an attending physician experienced in occupational
medicine in consultation with the surgeon or by the surgeon.
(d). Hardware removal may be necessary after
three to six months.
h. Patellar Subluxation:
i. Description/Definition: Incomplete
subluxation or dislocation of the patella. Recurrent episodes can lead to
subluxation syndrome that can cause frank dislocation of the patella. Patient
may report a buckling sensation, pain with extension, or a locking of the knee
with exertion.
ii. Occupational
Relationship: Primarily associated with a direct contact lateral force.
Secondary causes associated with shearing forces on the patella.
iii. Specific Physical Exam Findings: Lateral
retinacular tightness with associated medial retinacular weakness, swelling,
effusion, and marked pain with patellofemoral tracking/compression and glides.
In addition, other findings may include atrophy of muscles, positive patellar
apprehension test, and patella alta.
iv. Diagnostic Testing Procedures: CT or
Radiographs including Merchant views, Q-angle, and MRI for loose
bodies.
v. Non-Operative Treatment
Procedures
(a). Initial Treatment: Reduction
if necessary, ice, taping, and bracing followed by active therapy.
(b). Medications such as analgesics and
anti-inflammatories may be helpful. Refer to medication discussions in
Medications and Medical Management.
(c). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management.
(d). Benefits may be achieved through
therapeutic rehabilitation and rehabilitation interventions. They should
include range-of-motion (ROM), active therapies, and a home exercise program.
Active therapies include, proprioception training, restoring normal joint
mechanics, and clearing dysfunctions from distal and proximal structures.
Taping the patella or bracing may be beneficial. Passive as well as active
therapies can be used for control of pain and swelling. Therapy should progress
to strengthening and an independent home exercise program targeted to further
improve ROM, strength, and normal joint mechanics influenced by structures
distal and proximal to the knee. Specific strengthening should be done to
optimize patellofemoral mechanics and address distal foot mechanics that
influence the patellofemoral joint. Refer to Therapeutic Procedures,
Non-operative.
(i). Passive modalities are
most effective as adjunctive treatments to improve the results of active
treatment. They may be used as found in Therapeutic Procedures,
Non-operative.
(e).
Return to work with appropriate restrictions should be considered early in the
course of treatment. Refer to Return to Work.
(f). Other therapies in Therapeutic
Procedures, Non-operative may be employed in individual cases.
vi. Surgical
Indications/Considerations
(a). Fracture,
loose bodies, and recurrent dislocation. Surgical repair of first-time
dislocation in young adults generally is not recommended. Retinacular release,
quadriceps reefing, and patellar tendon transfer should only be considered for
subluxation after four to six months of active patient participation in
non-operative treatment.
(b). Prior
to surgical intervention, the patient and treating physician should identify
functional operative goals and the likelihood of achieving improved ability to
perform activities of daily living or work activities and the patient should
agree to comply with the pre- and post-operative treatment plan including home
exercise. The provider should be especially careful to make sure the patient
understands the amount of post-operative therapy required and the length of
partial- and full-disability expected post-operatively.
(c). Smoking may affect soft tissue healing
through tissue hypoxia. Patients should be strongly encouraged to stop smoking
and be provided with appropriate counseling by the physician.
vii. Operative Procedures:
arthroscopy with possible arthrotomy; debridement of soft tissue and articular
cartilage disruption; open reduction internal fixation with fracture;
retinacular release, quadriceps reefing, and patellar tendon or lateral release
with or without medial soft-tissue realignment.
viii. Post-operative Treatment
(a). Individualized rehabilitation program
based upon communication between the surgeon and the therapist using the
treatments found in Therapeutic Procedures, Non-operative.
(b). Treatment may include active therapy
with or without passive therapy, bracing.
(c). Return to work and restrictions after
surgery may be made by an attending physician experienced in occupational
medicine in consultation with the surgeon or by the surgeon.
i. Patellofemoral Pain
Syndrome (aka Retropatellar Pain Syndrome)
i.
Description/Definition. Patellofemoral pathologies are associated with
resultant weakening, instability, and pain of the patellofemoral mechanism.
Diagnoses can include patellofemoral chondromalacia, malalignment, persistent
quadriceps tendonitis, distal patellar tendonitis, patellofemoral arthrosis,
and symptomatic plica syndrome. Patient complains of pain, instability and
tenderness that interfere with daily living and work functions such as sitting
with bent knees, climbing stairs, squatting, running or cycling.
ii. Occupational Relationship: Usually
associated with contusion; repetitive patellar compressive forces; shearing
articular injuries associated with subluxation or dislocation of patella,
fractures, and/or infection.
iii.
Specific Physical Exam Findings: Findings on physical exam may include
retinacular tenderness, pain with patellar compressive ranging, positive
patellar glide test, atrophy of quadriceps muscles, positive patellar
apprehensive test. Associated anatomical findings may include increased Q
angle; ligament laxity, and effusion. Some studies suggest that the patellar
tilt test (assessing the patella for medial tilt) and looking for active
instability with the patient supine and knee flexed to 15 degrees and an
isometric quad contraction, may be most useful for distinguishing normal from
abnormal. Most patellar tests are more specific than sensitive.
iv. Diagnostic Testing Procedures:
Radiographs including tunnel view, axial view of patella at 30 degrees, lateral
view and Merchant views. MRI rarely identifies pathology. Occasional CT or bone
scans.
v. Non-Operative Treatment
Procedures
(a). Medications such as analgesics
and anti-inflammatories may be helpful. Refer to medication discussions in
Medications and Medical Management.
(b). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management.
(c). Benefits may be achieved through
therapeutic rehabilitation and rehabilitation interventions. The program should
include bracing and/or patellar taping, prone quad stretches, hip external
rotation, balanced strengthening, range-of-motion (ROM), active therapies and a
home exercise program. Active therapies include proprioception training,
restoring normal joint mechanics, and clearing dysfunctions from distal and
proximal structures. Passive as well as active therapies may be used for
control of pain and swelling. Active therapeutic exercise appears to decrease
pain; however, the expected functional benefits are unclear. Therapy should
progress to strengthening and an independent home exercise program targeted to
further improve ROM strength, and normal joint mechanics influenced by
structures distal and proximal to the knee. Refer to Therapeutic Procedures,
Non-operative.
(i). Passive modalities are
most effective as adjunctive treatments to improve the results of active
treatment. They may be used as found as adjunctive in Section F., Therapeutic
Procedures, Non-operative. Orthotics may be useful in some cases.
(d). Knee pain, when associated
with abnormal foot mechanics, may be favorably treated with appropriate
orthotics.
(i). There is some evidence that
pre-fabricated commercially available foot orthotic devices are more beneficial
for patients with patellofemoral pain syndrome than flat shoe inserts. They may
produce mild side effects such as rubbing or blistering which can be reduced
with additional empirical measures such as heat molding or addition, and
removal of wedges and inserts until patient comfort is achieved. In some cases,
custom semi-rigid or rigid orthotics is necessary to decrease pronation or
ensure a proper fit. There is no evidence regarding which orthotic design might
be useful.
(e).
Botulinum toxin injections for the relief of patellofemoral pain are considered
experimental and are not recommended.
(f). Steroid Injections
(i). Steroid injections may decrease
inflammation and allow the therapist to progress with functional exercise and
ROM. Steroid injections under significant pressure should be avoided as the
needle may be penetrating the tendon and injection into the tendon can cause
possible tendon breakdown, tendon degeneration, or rupture. Injections near the
patellar tendon should generally be avoided. Injections should be minimized for
patients less than 30 years of age.
[a]. Time
to Produce Effect: One injection.
[b]. Maximum Duration: Three injections in
one year spaced at least four to eight weeks apart.
(ii). Steroid injections should be used
cautiously in diabetic patients. Diabetic patients should be reminded to check
their blood glucose levels at least daily for two weeks after
injections.
(g).
Extracorporeal Shock Wave Therapy (ESWT): There is no good research to support
ESWT and therefore, it is not recommended.
(h). Return to work with appropriate
restrictions should be considered early in the course of treatment. Refer to
Return to Work.
(i). Other
therapies in Therapeutic Procedures, Non-operative may be employed in
individual cases.
vi.
Surgical Indications/Considerations: patellar tendon disruption, quadriceps
tendon rupture/avulsion, fracture. There is no evidence that surgery is better
than eccentric training for patellar tendonopathy of the inferior pole
(jumper's knee).
(a). Retinacular release,
quadriceps reefing, and tibial transfer procedures should only be considered
after four to six months of active patient participation in non-operative
treatment in young active patients. There is no evidence that arthroscopy for
patellofemoral syndrome is more efficacious than exercise.
(b). Lateral release and reconstruction is
not recommended for patellofemoral arthritis or middle aged adults.
(c). In cases of severe Grade III-IV isolated
patellofemoral arthritis where walking, steps, and other functional activities
are significantly impacted after adequate conservative treatment, prosthesis
may be considered in those less than 55 years. A patellofemoral arthroplasty is
generally contraindicated if there is patellofemoral instability or
malalignment, tibiofemoral mechanical malalignment, fixed loss of knee motion
(greater than 10 degrees extension or less than 110 degrees flexion),
inflammatory arthritis, and other systemic related issues. For patellar
resurfacing, refer to Knee Arthroplasty.
(d). Prior to surgical intervention, the
patient and treating physician should identify functional operative goals and
the likelihood of achieving improved ability to perform activities of daily
living or work activities and the patient should agree to comply with the pre-
and post-operative treatment plan including home exercise. The provider should
be especially careful to make sure the patient understands the amount of
post-operative therapy required and the length of partial- and full-disability
expected post-operatively.
(e).
Smoking may affect soft tissue healing through tissue hypoxia. Patients should
be strongly encouraged to stop smoking and be provided with appropriate
counseling by the physician.
vii Operative Procedures: Arthroscopic debridement of articular surface, plica, synovial tissue, loose bodies; arthrotomy; open reduction internal fixation with fracture; patellar prosthesis with isolated Grade III-IV OA, and possible patellectomy for young active patients with isolated arthritis.
viii. Post-Operative Treatment
(a). An individualized rehabilitation program
based upon communication between the surgeon and the therapist and using
therapies as outlined in Therapeutic Procedures, Non-operative.
(b). Treatment may include active therapy
with or without passive therapy; and bracing.
(c). Return to work and restrictions after
surgery may be made by an attending physician experienced in occupational
medicine in consultation with the surgeon or by the surgeon.
j. Posterior Cruciate
Ligament (PCL) Injury
i.
Description/Definition: Rupture of PCL. May be associated with concurrent ACL
rupture or collateral ligament injury.
ii. Occupational Relationship. Most often
caused by a posterior force directed to flexed knee.
iii. Specific Physical Exam Findings:
Findings on physical exam include acute effusion, instability, reverse
Lachman's test, reverse pivot shift, posterior drawer test.
iv. Diagnostic Testing Procedures: MRI,
radiographs including kneeling view, may reveal avulsed bone.
v. Non-operative Treatment Procedures:
(a). Initial Treatment: Ice, bracing, and
protected weight-bearing followed by active therapy.
(b). Medications such as analgesics and
anti-inflammatories may be helpful. Refer to medication discussions in
Medications and Medical Management.
(c). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management.
(d). Benefits may be achieved through
therapeutic rehabilitation and rehabilitation interventions. They should
include bracing then range-of-motion (ROM), active therapies, and a home
exercise program. Active therapies include proprioception training, restoring
normal joint mechanics, and clearing dysfunctions from distal and proximal
structures. Passive as well as active therapies may be used for control of pain
and swelling. Therapy should progress to strengthening and an independent home
exercise program targeted to further improve ROM, strength, and normal joint
structures distal and proximal to the knee. Refer to Therapeutic Procedures,
Non-operative.
(i). Passive modalities are
most effective as adjunctive treatments to improve the results of active
treatment. They may be used as found in Therapeutic Procedures,
Non-operative.
(e).
Return to work with appropriate restrictions should be considered early in the
course of treatment. Refer to Return to Work.
(f). Other therapies in Therapeutic
Procedures, Non-operative may be employed in individual cases.
vi. Surgical
Indications/Considerations:
(a). Carefully
consider the patients' normal daily activity level before initiation of
surgical intervention. Isolated Grade 1 instability does not require surgical
intervention. Grades 2 or 3 may have surgical intervention if there remains
demonstrable instability which interferes with athletic or work pursuits of the
patient. In a second degree strain there is significant posterior motion of the
tibia on the femur in active testing. A third degree strain demonstrates rotary
instability due to medial or lateral structural damage. Surgery is most
commonly done when the PCL rupture is accompanied by multi-ligament injury. Not
recommended as an isolated procedure in patients over 50 with Grade 3 or 4
osteoarthritis.
(b). Prior to
surgical intervention, the patient and treating physician should identify
functional operative goals and the likelihood of achieving improved ability to
perform activities of daily living or work activities and the patient should
agree to comply with the pre- and post-operative treatment plan including home
exercise. The provider should be especially careful to make sure the patient
understands the amount of post-operative therapy required and the length of
partial- and full-disability expected post-operatively.
(c). Smoking may affect soft tissue healing
through tissue hypoxia. Patients should be strongly encouraged to stop smoking
and be provided with appropriate counseling by the physician.
vi. Operative Procedures:
Autograft or allograft reconstruction.
vii. Post-Operative Treatment
(a). An individualized rehabilitation program
based upon communication between the surgeon and the therapist and using
therapies as outlined in Section F. Therapeutic Procedures,
Non-operative.
(b). Treatment may
include active therapy with or without passive therapy, bracing.
(c). Return to work and restrictions after
surgery may be made by an attending physician experienced in occupational
medicine in consultation with the surgeon or by the surgeon.
k. Tendonopathy
i. Description/Definition. Inflammation of
the lining of the tendon sheath or of the enclosed tendon. Usually occurs at
the point of insertion into bone or a point of muscular origin. Can be
associated with bursitis, calcium deposits, or systemic connective
diseases.
ii. Occupational
Relationship: Extreme or repetitive trauma, strain, or excessive unaccustomed
exercise or work.
iii. Specific
Physical Exam Findings: Involved tendons may be visibly swollen with possible
fluid accumulation and inflammation; popping or crepitus; and decreased
ROM.
iv. Diagnostic Testing
Procedures. Lab work may be done to rule out inflammatory disease. Other tests
are rarely indicated.
v.
Non-Operative Treatment Procedures
(a).
Initial Treatment: Ice, protected weight-bearing and/or restricted activity,
possible taping and/or bracing.
(b). Medications such as analgesics and
anti-inflammatories may be helpful. Refer to medication discussions in
Medications and Medical Management.
(c). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management.
(d). Benefits may be achieved through
therapeutic rehabilitation and rehabilitation interventions. They should
include range-of-motion (ROM), active therapies, including a home exercise
program. Active therapies include, proprioception training, restoring normal
joint mechanics, and clearing dysfunctions from distal and proximal structures.
Passive as well as active therapies may be used for control of pain and
swelling. Therapy should progress to strengthening and an independent home
exercise program targeted to further improve ROM, strength, and normal joint
mechanics influenced by structures distal and proximal to the knee. Refer to
Therapeutic Procedures, Non-operative.
(i).
Passive modalities are most effective as adjunctive treatments to improve the
results of active treatment. They may be used as found as adjunctive in
Therapeutic Procedures, Non-operative.
(e). For isolated patellar tendonopathy,
patellar tendon strapping or taping may be appropriate.
(f). Return to work with appropriate
restrictions should be considered early in the course of treatment. Refer to
Return to Work.
(g). Other
therapies in Therapeutic Procedures, Non-operative may be employed in
individual cases.
(h). Therapeutic
Injections: Steroid injections may decrease inflammation and allow the
therapist to progress with functional exercise and ROM. Steroid injections
under significant pressure should be avoided as the needle may be penetrating
the tendon and injection into the tendon can cause possible tendon breakdown,
tendon degeneration, or rupture. Injections should be minimized for patients
less than 30 years of age.
(i). Time to
Produce Effect: One injection.
(ii). Maximum Duration: Three injections in
one year spaced at least four to eight weeks apart.
(iii). Steroid injections should be used
cautiously in diabetic patients. Diabetic patients should be reminded to check
their blood glucose levels at least daily for two weeks after
injections.
vi. Surgical Indications/Considerations:
(a). Suspected avulsion fracture, or severe
functional impairment unresponsive to a minimum of four months of active
patient participation in non-operative treatment.
(b). Prior to surgical intervention, the
patient and treating physician should identify functional operative goals and
the likelihood of achieving improved ability to perform activities of daily
living or work activities and the patient should agree to comply with the pre-
and post-operative treatment plan including home exercise. The provider should
be especially careful to make sure the patient understands the amount of
post-operative therapy required and the length of partial- and full-disability
expected post-operatively.
(c).
Smoking may affect soft tissue healing through tissue hypoxia. Patients should
be strongly encouraged to stop smoking and be provided with appropriate
counseling by the physician.
vii. Operative Procedures: Tendon repair.
Rarely indicated and only after extensive conservative therapy.
viii. Post-Operative Treatment
(a). An individualized rehabilitation program
based upon communication between the surgeon and the therapist and using
therapies as outlined in Therapeutic Procedures, Non-Operative.
(b). Return to work and restrictions after
surgery may be made by an attending physician experienced in occupational
medicine in consultation with the surgeon or by the surgeon.
3. Hip and Leg
a. Acetabular Fracture
i. Description/Definition: Subgroup of pelvic
fractures with involvement of the hip articulation.
ii. Occupational Relationship: Usually from a
traumatic injury such as a fall or crush.
iii. Specific Physical Exam Findings:
Displaced fractures may have short and/or abnormally rotated lower
extremity.
iv. Diagnostic Testing
Procedures: Radiographs, CT scanning.
v. Non-Operative Treatment Procedures
(a). Initial Treatment: Although surgery is
frequently required, protected weight-bearing may be considered for
un-displaced fractures or minimally displaced fractures that do not involve the
weight-bearing surface of the acetabular dome.
(b). Medications such as analgesics and
anti-inflammatories may be helpful. Refer to medication discussions in
Medications and Medical Management.
(c). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management.
(d). Refer to comments on osteoporosis in
Ankle Sprain/Fracture.
(e). Smoking
may affect fracture healing. Patients should be strongly encouraged to stop
smoking and be provided with appropriate counseling by the physician.
(f). Benefits may be achieved through
therapeutic rehabilitation and rehabilitation interventions, after boney union
has been achieved. They should include bracing then range-of-motion (ROM),
active therapies, and a home exercise program. Active therapies include
ambulation with appropriate assistive device, proprioception training,
restoring normal joint mechanics, and clearing dysfunctions from adjacent
structures. Passive as well as active therapies may be used for control of pain
and swelling. Therapy should progress to strengthening and an independent home
exercise program targeted to further improve ROM, strength, and normal joint
mechanics influenced by proximal and distal structures. Therapy should include
training on the use of adaptive equipment and home and work site evaluations
when appropriate. Bracing may be appropriate. Refer to Therapeutic Procedures,
Non-Operative.
(i). Passive modalities are
most effective as adjunctive treatments to improve the results of active
treatment. They may be used as found as adjunctive in Therapeutic Procedures,
Non-operative.
(g).
Return to work with appropriate restrictions should be considered early in the
course of treatment. Refer to Return to Work.
(h). Other therapies in Therapeutic
Procedures, Non-operative may be employed in individual cases.
vi. Surgical
Indications/Considerations. Displaced or unstable fracture.
(a). Because smokers have a higher risk of
non-union and post-operative costs, it is recommended that insurers cover a
smoking cessation program peri-operatively. Physicians may monitor smoking
cessation with laboratory tests such as cotinine levels for long-term
cessation.
vii.
Operative Procedures: Usually open reduction and internal fixation or total hip
replacement.
viii. Post-Operative
Treatment
(a). An individualized
rehabilitation program based upon communication between the surgeon and the
therapist, and using therapies as outlined in Therapeutic Procedures,
Non-operative. In all cases, communication between the physician and therapist
is important to the timing of weight-bearing, and exercise
progressions.
(b). Treatment
usually includes active therapy with or without passive therapy for early range
of motion and weight-bearing then progression to, strengthening, flexibility,
neuromuscular training, and gait training with appropriate assistive
devices.
(c). Return to work and
restrictions after surgery may be made by an attending physician experienced in
occupational medicine in consultation with the surgeon or by the
surgeon.
b.
Aggravated Osteoarthritis
i.
Description/Definition: hip pain with radiographic evidence of joint space
narrowing or femoral acetabular osteophytes, and sedimentation rate less than
20mm/hr with symptoms. Patients usually have gradual onset of pain increasing
with use and relieved with rest, progressing to morning stiffness and then to
night pain.
ii. Occupational
Relationship: The provider must establish the occupational relationship by
establishing a change in the patient's baseline condition and a relationship to
work activities including but not limited to repetitive heavy lifting or
specific injury to the hip.
(a). Other
causative factors to consider: Prior significant injury to the hip may
predispose the joint to osteoarthritis. In order to entertain previous trauma
as a cause, the patient should have a medically documented injury with
radiographs or MRI showing the level of anatomic change. The prior injury
should have been at least two years from the presentation for the new
complaints and there should be a significant increase of pathology on the
affected side in comparison to the original imaging or operative reports and/or
the opposite un-injured side or extremity.
iii. Specific Physical Exam Findings:
Bilateral exam including knees and low back is necessary to rule out other
diagnoses. Pain with the hip in external and/or internal hip rotation with the
knee in extension is the strongest indicator.
iv. Diagnostic Testing Procedures: standing
pelvic radiographs demonstrating joint space narrowing to 2 mm or less,
osteophytes or sclerosis at the joint. MRI may be ordered to rule out other
more serious disease.
v.
Non-Operative Treatment Procedures
(a).
Medications such as analgesics and anti-inflammatories may be helpful. Refer to
medication discussions in Medications and Medical Management.
(b). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management. Patient education may also
include videos, telephone, follow-up, and pamphlets.
(c). Benefits may be achieved through
therapeutic rehabilitation and rehabilitation interventions. They should
include range-of-motion (ROM), active therapies and a home exercise program.
Active therapies include gait training with appropriate assistive devices,
proprioception training restoring normal joint mechanics, and clearing
dysfunctions from adjacent structures. Passive as well as active therapies may
be used for control of pain and swelling. Therapy should progress to
strengthening and an independent home exercise program targeted to further
improve ROM, strength, and normal joint mechanics influenced by proximal and
distal structures. Therapy should include training on the use of adaptive
equipment and home and work site evaluations when appropriate Refer to
Therapeutic Procedures, Non-operative. There is good evidence that a supervised
therapeutic exercise program with an element of strengthening is an effective
treatment for hip osteoarthritis.
(i).
Passive modalities are most effective as adjunctive treatments to improve the
results of active treatment. They may be used as found as adjunctive in
Therapeutic Procedures, Non-operative. There is some evidence that manual
therapy, including stretching and traction manipulation by a trained provider,
produces functional improvement in hip osteoarthritis and may be a suitable
treatment option.
[a]. Aquatic therapy may be
used as a type of active intervention to improve muscle strength and range of
motion when land-based therapy is not well-tolerated.
[b]. The use of insoles, adaptive equipment,
cane, may be beneficial.
[c]. There
is some evidence that acupuncture may produce improvement in hip pain and
function, making it a suitable treatment option for patients. Refer to
Therapeutic Procedures, Non-operative.
[d]. Steroid Injections - Steroid injections
may decrease inflammation and allow the therapist to progress with functional
exercise and ROM.
[i]. Time to Produce
Effect: One injection.
[ii].
Maximum Duration: Three injections in one year spaced at least four to eight
weeks apart.
[iii]. Steroid
injections should be used cautiously in diabetic patients. Diabetic patients
should be reminded to check their blood glucose levels at least daily for two
weeks after injections.
[e]. Return to work with appropriate
restrictions should be considered early in the course of treatment. Refer to
Return to Work.
[f]. Other
therapies in Therapeutic Procedures, Non-operative may be employed in
individual cases.
vi. Surgical Indications/Considerations
(a). When pain interferes with ADLs and the
patient meets the following: low surgical risk, adequate bone quality, and
failure of previous non-surgical interventions including weight control,
therapy with active patient participation, and medication. Refer to Therapeutic
Procedures-operative, Hip Arthroplasty, for indications specific to the
procedure.
(b). Prior to surgical
intervention, the patient and treating physician should identify functional
operative goals and the likelihood of achieving improved ability to perform
activities of daily living or work activities and the patient should agree to
comply with the pre- and post-operative treatment plan including home exercise.
The provider should be especially careful to make sure the patient understands
the amount of post-operative therapy required and the length of partial- and
full-disability expected post-operatively.
(c). In cases where surgery is
contraindicated due to obesity, it may be appropriate to recommend a weight
loss program if the patient is unsuccessful losing weight on their own.
Coverage for weight loss would continue only for motivated patients who have
demonstrated continual progress with weight loss.
(d). Because smokers have a higher risk of
non-union and post-operative costs, it is recommended that carriers cover a
smoking cessation program peri-operatively. Physicians may monitor smoking
cessation with laboratory tests such as cotinine levels for long-term
cessation.
vii.
Operative Procedures: Prosthetic replacement (traditional or minimally
invasive), or resurfacing.
viii.
Post-Operative Treatment
(a). In all cases,
communication between the physician and therapist is important to the timing of
weight-bearing and exercise progressions.
(b). For prosthetic replacement, refer to Hip
Arthroplasty.
(c). Return to work
and restrictions after surgery may be made by an attending physician
experienced in occupational medicine in consultation with the surgeon or by the
surgeon.
c.
Femoral Osteonecrosis (Avascular Necrosis (AVN) of the Femoral Head)
i. Description/Definition. Death of the bone
tissue of the femoral head following loss of blood supply to the area.
Destruction of the articular surfaces of the hip joint may lead to
arthritis.
ii. Occupational
Relationship. Trauma resulting in displaced subcapital fracture of the hip or
hip dislocation may cause AVN. Previous surgical procedures and systemic
steroids may lead to AVN. In the general population risk factors include, but
are not limited to alcohol abuse, smoking, Caisson disease (also known as the
bends), sickle cell anemia, autoimmune disease, and hypercoagulable states.
Often, the cause cannot be identified. Involvement of the opposite hip may
occur in more than half of cases not caused by trauma.
iii. Specific Physical Exam Findings. Hip or
groin pain made worse by motion or weight-bearing and alleviated by rest is the
classical presentation. Symptoms may begin gradually, often months after the
vascular compromise of blood flow. A limp may result from the limited
toleration of weight-bearing.
iv.
Diagnostic Testing Procedures. X-ray abnormalities include sclerotic changes,
cystic lesions, joint space narrowing, and degeneration of the acetabulum. The
x-ray may be normal in the first several months of the disease process. AVN
should be suspected when hip pain occurs and risk factors are present. X-rays
should be done first, but may be followed by an MRI. When AVN is not due to
trauma, both hips should be imaged.
v. Non-operative Treatment Procedures
(a). Initial Treatment: protected
weight-bearing and bracing followed by active therapy with or without passive
therapy. Conservative approaches may suffice when the lesion is small, but
larger lesions are expected to require surgical intervention when symptoms are
disabling.
(b). Medications such as
analgesics and anti-inflammatories may be helpful. Refer to medication
discussions in Medications and Medical Management.
(c). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, and weight management. Weight-bearing restrictions
may be appropriate.
(d). Smoking
may affect bone healing. Patients should be strongly encouraged to stop smoking
and be provided with appropriate counseling by the physician.
(e). Return to work with appropriate
restrictions should be considered early in the course of treatment. Refer to
Return to Work.
(f). Other
therapies in Therapeutic Procedures, Non-operative, may be employed in
individual cases.
vi.
Surgical Indications/Considerations: Core decompression may appropriate for
some patients with early disease (Stages 1 and 2A) who have functionally
disabling symptoms. Femoral head osteotomies or resurfacing hemiarthroplasties
may also be appropriate for younger patients when disease is limited to the
femoral head. Those 50 or older and patients with total joint collapse or
severely limiting disease will usually require an implant arthroplasty.
(a). Prior to surgical intervention, the
patient and treating physician should identify functional operative goals and
the likelihood of achieving improved ability to perform activities of daily
living or work activities and the patient should agree to comply with the pre-
and post-operative treatment plan including home exercise. The provider should
be especially careful to make sure the patient understands the amount of
post-operative therapy required and the length of partial- and full-disability
expected post-operatively.
(b).
Because smokers have a higher risk of non-union and post-operative costs, it is
recommended that insurers cover a smoking cessation program peri-operatively.
Physicians may monitor smoking cessation with laboratory tests such as cotinine
levels for long-term cessation.
vii. Operative Procedures. Osteotomy, core
decompression with or without bone graft, prosthetic replacement. Refer to
Therapeutic Procedures-operative for details.
viii. Post-operative Treatment
(a). Anticoagulant therapy to prevent deep
venous thrombosis for most procedures. Refer to Therapeutic Procedures,
Non-operative.

Treatment Procedures
(a). Initial Treatment.
Although surgery is usually required, non-operative procedures may be
considered in stable, non-displaced fractures and will require protected
weight-bearing.
(b). Medications
such as analgesics and anti-inflammatories may be helpful. Refer to medication
discussions in Medications and Medical Management.
(c). Back pain may occur after femur fracture
and should be addressed and treated as necessary.
(d). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, home
exercise, joint protection, weight management. Weight-bearing restrictions may
be appropriate.
(e). Refer to
comments related to osteoporosis in Therapeutic Procedures, Non-operative,
Osteoporosis Management.
(f).
Smoking may affect fracture healing. Patients should be strongly encouraged to
stop smoking and be provided with appropriate counseling by the
physician.
(g). Orthotics such as
heel lifts and custom shoe build-ups may be required when leg-length
discrepancy persists.
(h). Return
to work with appropriate restrictions should be considered early in the course
of treatment. Refer to Return to Work.
(i). Other therapies in Therapeutic
Procedures, Non-operative may be employed in individual cases.
vi. Surgical
Indications/Considerations. Femoral neck fracture or supracondylar femur
fracture with joint incongruity.

smokers have a higher risk of non-union and post-operative costs, it is
recommended that insurers cover a smoking cessation program peri-operatively.
Physicians may monitor smoking cessation with laboratory tests such as cotinine
levels for long-term cessation.
vii. Operative Procedures: Rod placement or
open internal fixation.
viii.
Post-Operative Treatment
(a). An
individualized rehabilitation program based upon communication between the
surgeon and the therapist, using therapies as outlined in Therapeutic
Procedures, Non-operative. In all cases, communication between the physician
and the therapist is important to the timing of weight-bearing and exercise
progression.
(b). Treatment usually
includes active therapy with or without passive therapy for protected
weight-bearing, early range of motion if joint involvement.
(c). Refer to bone-growth stimulators in
Therapeutic Procedures, Non-operative.

range-of-motion (ROM), active therapies, and a home exercise program. Active
therapies include proprioception training, restoring normal joint mechanics,
and clearing dysfunctions from adjacent structures. Passive as well as active
therapies may be used for control of pain and swelling. Therapy should progress
to strengthening and an independent home exercise program targeted to further
improve ROM, strength, and normal joint mechanics influenced by proximal and
distal structures. Bracing may be appropriate. Refer to Therapeutic Procedures,
Non-operative.
[i]. Passive modalities are
most effective as adjunctive treatments to improve the results of active
treatment. They may be used as found as adjunctive in Therapeutic Procedures,
Non-operative.
[e].
Return to work with appropriate restrictions should be considered early in the
course of treatment. Refer to Return to Work.
[f]. Other therapies in Therapeutic
Procedures, Non-operative may be employed in individual cases.
vi. Surgical
Indications/Considerations
(a). Surgery is
indicated for proximal or distal injuries only when significant functional
impairment is expected without repair. If surgery is indicated, it is
preferably performed within three months.
(b). Prior to surgical intervention, the
patient and treating physician should identify functional operative goals and
the likelihood of achieving improved ability to perform activities of daily
living or work activities and the patient should agree to comply with the pre-
and post-operative treatment plan including home exercise. The provider should
be especially careful to make sure the patient understands the amount of
post-operative therapy required and the length of partial- and full-disability
expected post-operatively.
(c).
Smoking may affect soft tissue healing through tissue hypoxia. Patients should
be strongly encouraged to stop smoking and be provided with appropriate
counseling by the physician.
vii. Operative Procedures: Re-attachment of
proximal avulsions and repair of distal tendon disruption.
viii. Post-Operative Treatment
(a). An individualized rehabilitation program
based upon communication between the surgeon and the therapist using therapies
as outlined in Therapeutic Procedures, Non-operative. In all cases,
communication between the physician and therapist is important to the timing of
weight-bearing and exercise progressions.
(b). Treatment may include protected
weight-bearing and active therapy with or without passive therapy. Splinting in
a functional brace may reduce time off work.
(c). Return to work and restrictions after
surgery may be made by an attending physician experienced in occupational
medicine in consultation with the surgeon or by the surgeon.

Impingement/Labral Tears
i.
Description/Definition: Two types of impingement are described pincer;
resulting from over coverage of the acetabulum and/or cam; resulting from
aspherical portion of the head and neck junction. Persistence of these
abnormalities can cause early arthritis or labral tears. Labral tears can also
be isolated; however, they are frequently accompanied by bony abnormalities.
Patients usually complain of catching or painful clicking which should be
distinguished from a snapping iliopsoas tibial tendon. A pinch while sitting
may be reported and hip or groin pain.
ii. Occupational Relationship: Impingement
abnormalities are usually congenital; however, they may be aggravated by
repetitive rotational force or trauma. Labral tears may accompany impingement
or result from high energy trauma.
iii. Specific Physical Exam Findings.
Positive labral tests.
iv.
Diagnostic Testing Procedures. Cross table laterals, standing AP pelvis and
frog leg lateral x-rays. MRI may reveal abnormality; however, false positives
and false negatives are also possible. MRI arthrogram with gadolinium should be
performed to diagnose labral tears, not a pelvic MRI. Intra-articular injection
should help rule out extra-articular pain generators. To confirm the diagnosis,
the patient should demonstrate changes on a pain scale accompanied by recorded
functional improvement post-injection. This is important, as labral tears do
not always cause pain and over-diagnosis is possible using imaging
alone.
v. Non-Operative Treatment
Procedures
(a). Medications such as analgesics
and anti-inflammatories may be helpful. Refer to medication discussions in
Medications and Medical Management.
(b). Patient education should include
instruction in self-management techniques, ergonomics, body mechanics, reducing
hip adduction and internal rotation home exercise, joint protection, and weight
management.
(c). Benefits may be
achieved through therapeutic rehabilitation and rehabilitation interventions.
They should include range-of-motion (ROM), active therapies and a home exercise
program. Active therapies include proprioception training, restoring normal
joint mechanics, and clearing dysfunctions from adjacent structures. Passive as
well as active therapies may be used for control of pain and swelling. Therapy
should progress to strengthening and an independent home exercise program
targeted to further improve ROM, strength, and normal joint mechanics
influenced by proximal and distal structures. Refer to Therapeutic Procedures,
Non-operative.
(i). Passive modalities are
most effective as adjunctive treatments to improve the results of active
treatment. They may be used as found as adjunctive in Therapeutic Procedures,
Non-operative.
(d).
Steroid Injections. Steroid injections may decrease inflammation and allow the
therapist to progress with functional exercise and ROM.
(i). Time to Produce Effect: One
injection.
(ii). Maximum Duration:
Three injections in one year spaced at least four to eight weeks
apart.
(iii). Steroid injections
should be used cautiously in diabetic patients. Diabetic patients should be
reminded to check their blood glucose levels at least daily for two weeks after
injections.
(e). Return
to work with appropriate restrictions should be considered early in the course
of treatment. Refer to Return to Work.
(f). Other therapies in Therapeutic
Procedures, Non-operative may be employed in individual cases.
vi. Surgical
Indications/Considerations:
(a). Surgery is
indicated when functional limitations persist after eight weeks of active
patient participation in treatment, there are clinical signs and symptoms
suggestive of the diagnosis and other diagnoses have been ruled out.
(b). Prior to surgical intervention, the
patient and treating physician should identify functional operative goals and
the likelihood of achieving improved ability to perform activities of daily
living or work activities and the patient should agree to comply with the pre-
and post-operative treatment plan including home exercise. The provider should
be especially careful to make sure the patient understands the amount of
post-operative therapy required and the length of partial- and full-disability
expected post-operatively.
(c). In
cases where surgery is contraindicated due to obesity, it may be appropriate to
recommend a weight loss program if the patient is unsuccessful losing weight on
their own. Coverage for weight loss would continue only for motivated patients
who have demonstrated continual progress with weight loss.
(d). Smoking may affect soft tissue healing
through tissue hypoxia. Patients should be strongly encouraged to stop smoking
and be provided with appropriate counseling by the physician.
