43-year-old male with pain. Evaluate for medial meniscus injury MENISCI: There is branching signal abnormality within the posterior horn and body of the medial meniscus indicating a complex but predominantly horizontal tear that extends to the femoral articular surface and also extends to the periphery of the posterior horn, decompressing into a small parameniscal cyst. The anterior horn appears intact. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is moderate degeneration of the articular cartilage of the patella with multiple partial and near full-thickness clefts/defects. There is also superficial degeneration of the articular cartilage of the femoral trochlea, centrally. We see no full-thickness articular cartilage defects of the tibiofemoral compartments. There is minimal subchondral bone marrow edema within the posteromedial aspect of the tibial plateau perhaps related to the overlying meniscal tear.LIGAMENTS: There is edema noted along the MCL which is nonspecific, but could represent a sprain in the correct clinical context. The ligament itself appears intact. The ACL and PCL appear intact. The LCL appears intact.EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Medial meniscus tear as described above.2. Degeneration of the articular cartilage of the patellofemoral joint.3. Edema along the MCL is nonspecific but could represent a sprain in the correct clinical context.4. Moderate size joint effusion other findings as described above.
