Reason: r/o tear of ACL graft History: pain, swelling MENISCI: There is linear decreased signal abnormality which traverses the posterior horn of the lateral meniscus and extends to the tibial articular surface indicating an oblique tear which extends into the body of the meniscus, new from prior examination. The anterior horn appears intact. The there is undersurface fraying of the posterior horn of the medial meniscus which otherwise appears intact.ARTICULAR CARTILAGE AND BONE: No full-thickness or near full-thickness articular cartilage defects are identified. There is thinning of the articular cartilage of the patellofemoral articulation. There is bone marrow signal abnormality within the lateral femoral condyle and lateral tibial plateau likely representing bone contusions. Note is made of osseous tunnels from prior ACL graft reconstruction.LIGAMENTS: Note is made of postsurgical changes of prior ACL graft reconstruction. There is near complete to complete rupture through the mid substance and distal fibers of the ACL graft, although some of the fibers of the graft may be intact. The PCL appears intact. The LCL appears intact. The imaged components of the anterolateral ligament appear intact.EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Near complete to complete rupture of the ACL graft as described above. 2. Tearing of the lateral meniscus as described above. 3. Bone contusions and other findings as described above.
