41-year-old female with right knee pain. Evaluate for medial meniscus tear and degenerative changes. MENISCI: There is a complex tear of the posterior horn of the medial meniscus with a radial component. The anterior horn of the medial meniscus appears normal. The anterior horn of the lateral meniscus is not visualized. The posterior horn of the lateral meniscus appears normal.ARTICULAR CARTILAGE AND BONE: There is generalized thinning of the articular cartilage along the femoral condyles and tibial plateaus. There is subchondral bone marrow edema within the lateral femoral condyle and lateral tibial plateau. There is generalized thinning of the articular cartilage along the patellar facets and femoral trochlea. There are several areas of partial thickness defects along the articular cartilage of the medial and lateral patellar facets with adjacent subchondral bone marrow edema. In addition there are areas of partial thickness defects along the articular cartilage of the femoral trochlea with adjacent subchondral bone marrow edema. There is residual red marrow noted more proximally within the imaged femur and tibia.LIGAMENTS: The cruciate and collateral ligaments appear normal.EXTENSOR MECHANISM: The extensor mechanism appears normal.ADDITIONAL
1. Complex tear of the posterior horn of the medial meniscus with a radial component. The anterior horn of lateral meniscus is not visualized.2. Moderate articular cartilage thinning and degeneration and other findings as described above.
