MENISCI: There is increased signal abnormality within the posterior horn of the medial meniscus consistent with intrasubstance degeneration. The medial meniscus appears intact. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is full-thickness articular cartilage degeneration along the lateral facet of the patella with underlying subchondral signal abnormality likely degenerative in etiology. There is a near full-thickness cleft of the articular cartilage, along the lateral facet, centrally. There is near full-thickness articular cartilage degeneration along the medial facet of the femoral trochlea, appearing progressed when compared to the prior study. There is full-thickness articular cartilage degeneration, centrally, affecting the femoral trochlea.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
