Evaluate for medial meniscus tear. McMurray positive. Joint line tenderness. Not responding to conservative treatment. Pain for many months. Worse with activity. Swelling. MENISCI: There is intermediate globular signal abnormality in the body and posterior horn of the medial meniscus. Distinct loss of the apical aspect of the body of the medial meniscus extending to the posterior horn is noted, likely representing an oblique tear. Signal characteristics and morphology of the lateral meniscus are unremarkable.ARTICULAR CARTILAGE AND BONE: There is no significant abnormality of the articular cartilage. Increased marrow signal in the medial tibial plateau and intercondylar region of the femur suggest bone contusions.LIGAMENTS: There is near complete tearing of the anterior cruciate ligament with mild retraction and some fibers seen anterior to the tibial attachment.. Posterior cruciate ligament is intact. EXTENSOR MECHANISM: There is mild redundancy of the patellar tendon without definite underlying signal abnormality, of uncertain clinical significance.ADDITIONAL
Near complete ACL tear, as above.Degenerative signal abnormality with superimposed oblique tear in the body and posterior horn of the medial meniscus.
