Reason: R/O Tear History: Right knee pain MENISCI: There is a complex tear of the posterior horn of the medial meniscus with a radial component. There is associated medial extrusion of the body of the medial meniscus. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is full-thickness articular cartilage degeneration along the weightbearing portion of the medial femoral condyle and medial tibial plateau with underlying degenerative subchondral signal abnormality. There is relative sparing of the lateral tibiofemoral compartment articular cartilage. There is superficial fraying of the articular cartilage along the lateral facet of the patella. There is a linear focus of low signal abnormality within the femoral trochlea, centrally, consistent with an articular cartilage cleft. There are tricompartmental osteophytes.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Complex tear of the posterior horn of the medial meniscus with extrusion of the body of the medial meniscus.2. Moderate-sized joint effusion.3. Osteoarthritis of the right knee with articular cartilage degeneration/clefts as described above.
