Reason: left knee pain History: left knee pain MENISCI: There is linear increased signal abnormality which traverses the anterior horn of the lateral meniscus and extends to the tibial and femoral articular surfaces indicating longitudinal tear which may extend to involve the free edge of the body of the meniscus. The posterior horn appears intact. The medial meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is focal partial thickness articular cartilage degeneration along the weightbearing surface of the lateral femoral condyle above the body of the meniscus. There is a focal near full-thickness articular cartilage degeneration along the anterior aspect of the medial tibial plateau. The medial compartment articular cartilage otherwise appears intact. There is superficial fraying of the articular cartilage along the median evidence of the patella inferiorly.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Longitudinal tear of the lateral meniscus.2. Articular cartilage degeneration most pronounced along the lateral tibiofemoral compartment as described above. Other findings as described above.
