Reason: left medial meniscal tear? History: medial left knee pain with positive McMurray's and Apley's tests MENISCI: There is increased signal intensity along the undersurface of the posterior horn of the medial meniscus indicating a tear. There is slight blunting of the free edge of the body of the medial meniscus which may represent fraying. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There are surgical changes within the weightbearing portion of the medial femoral condyle suggestive of osteochondral fixation or transfer. There is heterogeneity of the overlying cartilage, likely representing a combination of degeneration and tearing with possible focal delamination anteriorly. There is edema type signal within the adjacent subchondral marrow. There is also degeneration of the adjacent cartilage of the medial tibial plateau with focal delamination and subchondral edema. There is mild superficial blistering along the lateral facet of the patella as well as thinning of the articular cartilage of the far medial facet of the patella. There are small tricompartmental osteophytes.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Surgical changes of medial femoral condyle osteochondral fixation or transfer with degeneration and tearing of the overlying cartilage as well as tearing of the articular cartilage of the adjacent medial tibial plateau.2. Undersurface tear of the posterior horn of the medial meniscus.3. Other findings as described above.
