Knee pain. Question of meniscal injury. MENISCI: There is blunting of the posterior horn of the medial meniscus compatible with a radial tear. The lateral meniscus is intact. ARTICULAR CARTILAGE AND BONE: There is full thickness articular cartilage loss of the medial facet of the patella measuring approximately 12 mm in the transverse dimension with underlying subchondral reactive edema. There is significant thinning of the articular cartilage of the median eminence of the patella and medial aspect of the lateral facet with underlying subchondral reactive edema. There is near full thickness to full thickness degeneration and heterogeneity of the trochlear groove and lateral femoral trochlea with underlying reactive bone edema. There is thinning of the articular cartilage of the anterior and weightbearing portion of the medial femoral condyle with superficial delamination between the meniscal horns. There is thinning of the weightbearing portion of the lateral femoral condyle articular cartilage along with focal fissures along the posterior condyle. There is edema within the medial tibial plateau. LIGAMENTS: The collateral and cruciate ligaments are intact. EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1. Small radial tear of the posterior horn of the medial meniscus. 2. Chondromalacia as described above.3. Large Baker's cyst.
