56-year-old male patient with pain. Evaluate for meniscal tear. MENISCI: Again seen is a complex tear of the posterior horn of the medial meniscus and blunting of the free edge of the posterior horn, similar to prior.Complex meniscal tearing including horizontal and vertical components, predominantly affecting the posterior horn and body, as well as blunting of the free edge appears similar to prior.ARTICULAR CARTILAGE AND BONE: Tricompartmental osteophytes are noted. There is a full-thickness chondral defect in the weightbearing portion of the medial femoral condyle, progressed compared to prior MRI. This defect measures up to 2.3 cm in AP dimension and 1.3 cm in mediolateral dimension. There is also a large area of full-thickness chondral loss in the weightbearing portion of the medial tibial plateau with subtle subchondral reactive marrow changes. There are numerous chondral defects in the posterior weightbearing portions of the lateral compartment, similar to prior. There is thinning and partial-thickness fissuring of the patellar cartilage.LIGAMENTS: The anterior cruciate ligament is not visualized, unchanged compared prior examination and compatible with a chronic full-thickness tear. The posterior collateral ligament, medial collateral ligament, lateral collateral ligament complex, and patellar retinacula are intact.EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1.Tricompartmental chondromalacia with progression of full-thickness chondral defects in the medial compartment.2.No significant interval change in medial and lateral meniscal complex tearing.3.Baker's cyst containing at least one loose body.4.Chronic anterior cruciate ligament tear.
