48-year-old female with left knee pain and clicking. Evaluate for meniscal tear. MENISCI: There is globular increased signal abnormality within the posterior horn of the medial meniscus. There is increased signal abnormality and blunting/deformity of the free edge of the body of the medial meniscus which appears to extend to the femoral articular surface, which has an irregular contour, consistent with degenerative tearing. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is focal near full-thickness articular cartilage degeneration along the medial femoral condyle with underlying bone marrow edema type signal abnormality. There is also focal full-thickness articular cartilage degeneration along the weightbearing surface of the medial femoral condyle overlying the body and posterior horn of the medial meniscus.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact. ADDITIONAL
