73-year-old male with left knee pain and question of medial meniscal tear. MENISCI: Laterally, there is a complex predominantly transverse tear of the posterior horn. The lateral posterior horn also appears small, indicative of multifocal tearing. There is also desiccation of the superior aspect of the anterior horn of the lateral meniscus. Incidentally noted is a well visualized anterior meniscal femoral ligament seen just anterior to the PCL.ARTICULAR CARTILAGE AND BONE: There is thinning with associated sclerosis within the posterior femoral articulation of the medial epicondyle. The far medial aspect of the tibial articular cartilage appears degraded with bony uncovering.LIGAMENTS: There is mild fraying and signal abnormality of the ACL though fibers appear to be intact. The PCL is within normal limits. The LCL complex appears intact. There is mild signal abnormality about the MCL, likely indicative of strain, however the fibers of the MCL appear intact.EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Degenerative changes including complex tearing of the medial meniscus as specifically outlined above.2. Osteoarthritis with articular cartilage degeneration of the medial tibiofemoral articulation as above. 3. Small joint effusion.
