Female, 55 years old. Medial knee pain MENISCI: The body of the medial meniscus is extruded with abnormal signal and morphology, compatible with degeneration and complex tearing. The posterior horn of the medial meniscus appears blunted. The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is a large area of full-thickness cartilage loss involving the medial femoral condyle measuring up to approximately 1 cm in mediolateral dimension and 2 cm in AP dimension, with underlying bone marrow edema. There is also full-thickness cartilage loss involving the medial tibial plateau with underlying bone marrow edema. There is mild diffuse thinning of the lateral compartment articular cartilage without focal defect identified. The patellar cartilage is grossly intact. There are tricompartmental osteophytes.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1.High-grade cartilage loss involving the medial femoral condyle and medial tibial plateau as above.2.Complex tearing of the medial meniscus.
