Mechanical symptoms, medial knee pain. Evaluate for meniscus and loose body. MENISCI: The inner aspect of the body of the medial meniscus is not visualized. There is irregularity and blunting of the posterior horn of the medial meniscus compatible with a complex tear. The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is near full thickness loss of the articular cartilage of the weight-bearing portion of the medial femoral condyle and thinning of the articular cartilage more anteriorly. Additionally there is full thickness loss of the articular cartilage of the anterior lateral femoral condyle with subchondral edema, appearing similar to the prior study. Focal areas of near full thickness to full-thickness loss are also noted within the posterior lateral femoral condyle articular cartilage. There is thinning and heterogeneity of the lateral facet articular cartilage of the patella indicating degeneration with minimal subchondral edema. Partial thickness fissuring is also noted about the median eminence. There is thinning of the lateral femoral trochlea articular cartilage.Medial compartment osteophytes are noted.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1. Complex tear of the posterior horn of the medial meniscus. 2. Chondromalacia as described above.
