Male 46 years old s/p meniscal and ACL repairs; new injury with new pain and laxity. MENISCI: There has been repair of the radial tear of the lateral meniscus. Residual tear or repair is seen along the inner margin of the body of the lateral meniscus. Degenerative changes seen at the posterior root of the lateral meniscus, compatible with postsurgical changes.Branching linear signal indicating tearing within the posterior horn and body of the medial meniscus appears new. There is no meniscal extrusion.ARTICULAR CARTILAGE AND BONE: Bone marrow signal intensity is within normal limits. There are changes from prior ACL reconstruction.There is mild thinning of the articular cartilage along the lateral surface of the patella and a focus of edema signal in the marrow but no evidence of full-thickness cartilage defect. The articular cartilage of the medial and lateral compartments is preserved.LIGAMENTS: There is mild thickening of the ACL graft but the fibers are intact. The PCL, MCL and lateral collateral ligament complex are intact. EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
