Left knee pain. Left knee lateral meniscus tear? MENISCI: There is extensive complex tearing of the body and posterior horn of the lateral meniscus, with portions of the meniscus macerated to the point of being almost nonexistent. The anterior horn of the lateral meniscus is relatively intact. There is poorly defined band-like increased signal intensity within the posterior horn of the medial meniscus that extends to the femoral articular surface suggestive of a degenerative horizontal tear, but the true clinical significance of this is uncertain.ARTICULAR CARTILAGE AND BONE: There is full-thickness loss of articular cartilage along the posterior aspect of the lateral femoral condyle and posterior aspect of the lateral tibial plateau with degenerative edema-type signal in the underlying subchondral bone. There are also prominent osteophytes arising from the lateral femoral condyle and lateral tibial plateau. The articular cartilage of the medial and patellofemoral compartments appears relatively preserved.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
Maceration of the lateral meniscus with severe osteoarthritis affecting the lateral tibiofemoral compartment and other findings as described above.
