Reason: Lateral meniscus tear History: left knee pain MENISCI: There is mild undersurface fraying of the posterior horn of the medial meniscus. The lateral meniscus appears normal. No meniscal tear. ARTICULAR CARTILAGE AND BONE: There is diffuse thinning of the articular cartilage of the knee, particularly notable along the lateral aspect of the patellofemoral compartment where there is underlying subchondral cyst formation compatible with underlying osteoarthritis. No full-thickness tear in the articular cartilage of the knee is evident. Bone marrow signal is within normal limits throughout.LIGAMENTS: The cruciate and collateral ligaments of the left knee appear intact. EXTENSOR MECHANISM: The quadriceps and patellar tendons appear intact.ADDITIONAL
1. Mild undersurface fraying of the posterior horn of the medial meniscus, but no meniscal tear is evident.2. Moderate osteoarthritis of the knee, particularly affecting the patellofemoral compartment.
