Left knee pain. Question of meniscal tear or pathology. MENISCI: There is abnormal signal and ghosting of the posterior horn of the medial meniscus which may represent a radial tear. The lateral meniscus is intact. ARTICULAR CARTILAGE AND BONE: There is near complete loss of the articular cartilage of the anterior lateral femoral condyle. There is significant chondral thinning and fraying of the weight-bearing portion of the medial femoral condyle. There is near complete loss of cartilage of the femoral trochlea with minimal cartilage remaining along the superior aspect. There is complete cartilage loss of the lateral patellar facet with bone on bone apposition and subchondral cyst formation inferiorly. There is tricompartmental osteophyte formation. LIGAMENTS: The collateral and cruciate ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Tricompartmental articular cartilage loss, most predominately affecting the lateral patellar facet and anterior lateral femoral condyle.2. Probable radial tear of the posterior horn of the medial meniscus.3. Severe osteoarthritis of the patellofemoral joint. 4. Moderate joint effusion.
