39 year old female. Pain. Evaluate for meniscal tear. MENISCI: The body of the lateral meniscus is markedly attenuated and deformed compatible with extensive tearing assuming no prior meniscectomy. There is also less severe deformity and attenuation of the posterior horn of the lateral meniscus with intrasubstance signal in the posterior and anterior horns contacting the tibial articular surface suggesting additional tearing. The medial meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is near full thickness degeneration of the articular cartilage of the lateral tibial plateau beneath the posterior horn of the lateral meniscus. There is moderate thinning of the articular cartilage of the lateral femoral condyle above the posterior horn of the lateral meniscus. Additional focal degeneration along the far posterior cartilage of the lateral femoral condyle is noted.LIGAMENTS: The collateral and cruciate ligaments are intact.EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
Lateral meniscal tear, lateral compartment chondral degeneration, and ossified loose body, as described above.
