In a patient with knee symptoms (pain, swelling, locking, catching, popping, giving way) and/or signs (tenderness, effusion, loss of motion, crepitus), x-rays (including AP, lateral, sunrise/Merchant, and tunnel views) are an option.
Strength of Recommendation: Weak*
*To see the description of the evidence linked to the strength of the recommendations, please refer to Table 1; “Strength of Recommendation descriptions” in the guideline.
We are unable to recommend for or against x-rays on the contralateral asymptomatic knee in patients with confirmed OCD of one knee.
Strength of Recommendation: Inconclusive
In a patient with a known OCD lesion on x-ray, an MRI of the knee is an option to characterize the OCD lesion or when concomitant knee pathology is suspected such as meniscal pathology, ACL injury, or articular cartilage injury.
Strength of Recommendation: Weak
We are unable to recommend for or against non-operative treatment (casting, bracing, splinting, unloader brace, electrical or ultrasound bone stimulators, or activity restriction alone) for asymptomatic skeletally immature patients with OCD.
Strength of Recommendation: Inconclusive
We are unable to recommend for or against a specific non-operative treatment (casting, bracing, splinting, unloader brace, electrical or ultrasound bone stimulators, or activity restriction alone) for symptomatic skeletally immature patients with OCD.
Strength of Recommendation: Inconclusive
We are unable to recommend for or against arthroscopic drilling in symptomatic skeletally immature patients with a stable lesion(s) who have failed to heal with non operative treatment for at least three months.
Strength of Recommendation: Inconclusive
In the absence of reliable evidence, it is the opinion of the work group that symptomatic skeletally immature patients with salvageable unstable or displaced OCD lesions be offered the option of surgery.
Strength of Recommendation: Consensus
We are unable to recommend for or against a specific cartilage repair technique in symptomatic skeletally immature patients with unsalvageable fragment.
Strength of Recommendation: Inconclusive
We are unable to recommend for or against repeat MRI for asymptomatic skeletally mature patients.
Strength of Recommendation: Inconclusive
We are unable to recommend for or against treating asymptomatic skeletally mature patients with OCD progression (as identified by X-ray or MRI) like symptomatic patients.
Strength of Recommendation: Inconclusive
In the absence of reliable evidence, it is the opinion of the work group that symptomatic skeletally mature patients with salvageable unstable or displaced OCD lesions be offered the option of surgery.
Strength of Recommendation: Consensus
We are unable to recommend for or against a specific cartilage repair technique in symptomatic skeletally mature patients with unsalvageable OCD lesions.
Strength of Recommendation: Inconclusive
In the absence of reliable evidence, it is the opinion of the work group that patients who remain symptomatic after treatment for OCD have a history and physical examination, x-rays and/or MRI to assess healing.
Strength of Recommendation: Consensus
We are unable to recommend for or against physical therapy for patients with OCD treated non-operatively.
Strength of Recommendation: Inconclusive
In the absence of reliable evidence, it is the opinion of the work group that patients who have received surgical treatment of OCD be offered post-operative physical therapy.
Strength of Recommendation: Consensus
We are unable to recommend for or against counseling patients about whether activity modification and weight control prevents onset and progression of OCD to osteoarthritis (osteoarthrosis).
Strength of Recommendation: Inconclusive
