60-year-old female with knee pain. Assess for lateral meniscus tear. MENISCI: There is linear increased signal abnormality within the posterior horn of the lateral meniscus which extends to the tibial and femoral articular surfaces consistent with a complex tear with both a vertical and horizontal component. The anterior horn of the lateral meniscus appears intact. The medial meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is full-thickness articular cartilage degeneration along the weightbearing surface of the lateral femoral condyle above the posterior horn of the meniscus. There is relative sparing of the articular cartilage of the medial compartment. There is fraying of the articular cartilage of the patella, centrally.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Complex tear of the lateral meniscus as described above.2. Articular cartilage degeneration as described above.
