Left knee pain and OCD lesion of tibia. MENISCI: The posterior horn of the lateral meniscus is frayed, similar to the prior study. The medial meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is a heterogeneous lesion with small cysts in the lateral tibial plateau without significant change from the previous study. There is no disruption of the articular cartilage. There may be an old osteochondral defect with subchondral cystic change, but this appears stable from the prior study. There is no evidence of loosening. There is mild adjacent bone marrow edema, similar to the prior study. LIGAMENTS: The ACL, PCL, MCL, and LCL are intact. EXTENSOR MECHANISM: What was previously described as a short segment partial-thickness tear through the distal patellar tendon is most likely a normal variant of the patellar tendon with a cleft, appearing similar to the prior study.ADDITIONAL
