Knee pain and tenderness without improvement with conservative management. MENISCI: Intermediate signal within the posterior horn of the medial meniscus is compatible with mucoid degeneration without discrete tears. The lateral meniscus is within normal limits.ARTICULAR CARTILAGE AND BONE: Bone marrow signal intensity is within normal limits without evidence of fracture. There is generalized thinning of the patellofemoral cartilage. The articular cartilage is otherwise intact.LIGAMENTS: There is discontinuity of the fibers of the anterior cruciate ligament compatible with complete tear. The posterior cruciate ligament is intact. The collateral ligaments are intact. EXTENSOR MECHANISM: Extensor mechanisms is intact.ADDITIONAL
Complete tear of the anterior cruciate ligament, favor chronic injury given lack of associated bone contusions or joint effusion. Additional findings as described above.
