Right knee pain and swelling. Evaluate right knee for lateral meniscus tear versus chondromalacia. MENISCI: There is increased intrasubstance signal within the lateral meniscus indicating mild mucoid degeneration. Within the body of the lateral meniscus, the signal appears to extend to the femoral articular surface near the free edge of the meniscus suggesting inner edge fraying or mild inner edge tearing. We see no findings to suggest an unstable lateral meniscus tear. The medial meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is both superficial fraying as well as near full thickness to full-thickness fissuring of the articular cartilage of the medial facet of the patella. There is mild heterogeneity of the the cartilage of the lateral facet of the patella suggesting relatively mild degeneration. There is near full-thickness degeneration of the articular cartilage of the medial femoral condyle along the weight-bearing portion between the meniscal horns. There is also perhaps mild superficial degeneration of the articular cartilage of the anterior aspect of the medial tibial plateau. The lateral compartment articular cartilage is intactLIGAMENTS: The collateral and cruciate ligaments are intact. EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1. Cartilage degeneration as described above affecting the patella and medial compartments.2. Lateral meniscal degeneration with possible degenerative fraying/tearing along the free edge of the body, but we see no specific features to suggest an unstable tear.
