Knee pain, evaluate for medial meniscal tear. MENISCI: Linear abnormal signal intensity within the body and posterior horn of the medial meniscus as best seen on the coronal view (series 801, image 20) is compatible with a vertical tear. The anterior horn of the medial meniscus appears intact. The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is diffuse thinning of the articular cartilage of the weightbearing portion of the medial femoral condyle with underlying reactive bone marrow edema but without discrete full-thickness cartilaginous defects. The articular cartilage of the lateral tibiofemoral compartment is grossly intact. There is marked thinning of the articular cartilage of the medial patellar facet without full-thickness defects. The remaining cartilage of the patellofemoral compartment is grossly intact.LIGAMENTS: The collateral and cruciate ligaments are intact. EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
