Osteochondritis Dissecans, Right Knee

ICD-10 Code
M93.21

Clinical Presentation & Protocol

Patient Usually Complains Of

Patient presents with chronic right knee pain, localized to the medial femoral condyle, exacerbated by weight-bearing activities. Reports intermittent mechanical symptoms including locking, catching, and localized swelling. No history of acute trauma. Pain is described as a dull ache, rated [X]/10, with occasional episodes of sharp pain during terminal extension.

Clinical Examination Findings

Right knee examination reveals mild joint line tenderness, specifically at the medial femoral condyle. Wilsonโ€™s test is positive for pain reproduction. Range of motion is limited by discomfort at terminal extension. Mild effusion noted; no ligamentous instability (Lachman, anterior/posterior drawer tests negative). Gait demonstrates a slight antalgic component.

Treatment Protocol

Initial management includes activity modification, cessation of high-impact sports, and protected weight-bearing with crutches as needed. Physical therapy initiated for quadriceps strengthening and range of motion maintenance. Imaging follow-up (MRI) scheduled to assess lesion stability. If lesion is unstable or symptomatic despite conservative measures, surgical consultation for internal fixation or debridement will be considered.
