Effusion and positive McMurray's. MENISCI: There is a complex tear with both radial and vertical components and fragmentation of the posterior horn of the medial meniscus. The lateral meniscus is intact. ARTICULAR CARTILAGE AND BONE: There is full thickness loss of articular cartilage of the weight-bearing portion of the medial femoral condyle in between the meniscal horns. There is also thinning of the articular cartilage of the weight-bearing portion of the medial tibial plateau along the medial aspect. The articular cartilage of the lateral compartment is intact. There is partial thickness heterogeneity of the lateral facet articular cartilage of the patella compatible with degeneration. The trochlear cartilage is intact. There is mild edema along the medial aspect of the medial tibial plateau.LIGAMENTS: The collateral and cruciate ligaments are intact.EXTENSOR MECHANISM: Increased T2 signal in the soft tissues anterior to the patellar tendon may reflect a prepatellar bursitis.ADDITIONAL
1. Complex tearing of the posterior horn of the medial meniscus.2. Chondromalacia as described above.
