Reason: eval knee, s.p ACL recon. MARS protocol History: swelling MENISCI: There is blunting of the free edge of the anterior horn and body of the lateral meniscus likely representing superficial fraying. The meniscus otherwise appears intact.There is linear fluid signal abnormality within the posterior horn of the medial meniscus which extends to the tibial articular surface indicating a longitudinal tear.ARTICULAR CARTILAGE AND BONE: There is a focal near full-thickness to full-thickness articular cartilage defect along the weightbearing surface of the lateral femoral condyle above the posterior horn of the lateral meniscus. There is bone marrow signal abnormality in the underlying area likely degenerative in etiology. There is partial-thickness articular cartilage degeneration along the weightbearing surface of the lateral femoral condyle, more anteriorly.The patellofemoral articular cartilage appears relatively spared.LIGAMENTS: The cruciate and collateral ligaments appear intact. Note is made of postsurgical changes of prior ACL graft reconstruction EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Findings consistent with the stated history of ACL graft reconstruction. The graft appears intact.2. Longitudinal tear of the posterior horn of the medial meniscus.3. Superficial fraying of the free edge of the lateral meniscus.4. Focal full-thickness articular cartilage defect along the lateral femoral condyle.5. Mucoid degeneration of the PCL.
