45-year-old female with pain. Due to the patient's body habitus, the high-definition coil could not be utilized resulting in slightly suboptimal image quality.MENISCI: There is blunting and deformity of the posterior horn of the medial meniscus consistent with complex degenerative tearing which extends to the body of the meniscus. The anterior horn appears intact. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is full-thickness articular cartilage degeneration along the weightbearing surface of the medial femoral condyle and medial tibial plateau with underlying degenerative subchondral signal abnormality. There is partial-thickness articular cartilage degeneration along the lateral tibiofemoral compartment. There is full-thickness articular cartilage degeneration affecting the patellofemoral joint most pronounced along the lateral facet of the patella with underlying subchondral signal abnormality. There are tricompartmental osteophytes.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Severe degenerative osteoarthritic changes of the knee most pronounced along the medial tibiofemoral compartment. Complex degenerative tearing of the medial meniscus.2. Large joint effusion and Baker's cyst with foci of low signal internal debris which may reflect a synovitis.
