Reason: Lat Meniscus Tear History: left knee pain / Lat Jt Line MENISCI: There is blunting of the posterior horn of the lateral meniscus likely representing a combination of degeneration, prior tearing, and postsurgical change from prior partial meniscectomy. No fluid-filled tear is evident. There is blunting of the posterior horn of the medial meniscus which also may represent prior tearing and postsurgical change from prior partial meniscectomy, appearing similar to the prior study. No fluid-filled or unstable tear is evident.ARTICULAR CARTILAGE AND BONE: There is full-thickness articular cartilage degeneration along the weightbearing surface of the lateral femoral condyle above the posterior horn of the meniscus which has progressed slightly when compared to the prior study. There is underlying subchondral signal abnormality and cyst formation likely degenerative in etiology. There is focal decreased signal abnormality affecting the articular cartilage along the posterior aspect of the lateral femoral condyle which may represent a full-thickness articular cartilage fissure. There is relative sparing of the patellofemoral articulation cartilage. There are small osteophytes affecting the lateral tibiofemoral compartment.LIGAMENTS: Note is made of postsurgical changes of prior ACL graft reconstruction. The graft appears intact. The PCL appears intact. The MCL and LCL appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact, although the distal fibers of the patellar tendon are obscured by metal susceptibility artifact related to the patient's ACL graft reconstruction.ADDITIONAL
