Right knee pain MENISCI: There is increased horizontal signal within the posterior horn of the medial meniscus, reflecting tear. There is mild extrusion of the meniscus into the medial gutter although the root appears intact. The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is full-thickness cartilage loss of the medial compartment of both the femoral condyle and tibial plateau there is associated degenerative marrow signal within the underlying bone. The articular cartilage of the lateral compartment is relatively preserved. There is thinning of the articular cartilage of the femoral trochlea without full-thickness defect of the patellar cartilage.LIGAMENTS: No significant abnormality noted. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Horizontal tear of the posterior horn of the medial meniscus with mild extrusion.2. Full-thickness cartilage loss of the medial compartment with milder thinning of the patellofemoral and lateral compartments.3. Small joint effusion and mild synovitis.
