Knee pain. Meniscal tear? MENISCI: There is blunting of the free edge of the posterior horn of the medial meniscus indicating tearing of the inner-most fibers. There is also increased signal within the posterior horn and body of the medial meniscus indicating intrasubstance degeneration with poorly defined signal extending to the blunted free edge and undersurface of the meniscus, suggesting additional degenerative tearing/fraying. The anterior horn of the medial meniscus appears intact.There is increased signal intensity within the body and posterior horn of the lateral meniscus indicating intrasubstance degeneration with extension to the tibial articular surface suggesting degenerative undersurface tearing/fraying. The anterior horn of the lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is near full-thickness to full-thickness degeneration of the articular cartilage of the medial tibial plateau just lateral to the free edge of the body of the meniscus, with degenerative edema-type signal in the underlying subchondral bone. There is diffuse thinning of the articular cartilage of the weightbearing portion of the medial femoral condyle. There appears to be full-thickness degeneration of the articular cartilage of the lateral tibial plateau posteriorly, beneath the posterior horn of the lateral meniscus. Subjectively, the articular cartilage of the patella appears thinned, with more focal superficial degeneration of the articular cartilage of the medial facet. There is also a partial thickness cleft of the articular cartilage of the femoral trochlea, best seen on the sagittal sequences.LIGAMENTS: The cruciate and collateral ligaments appear intact. A small amount of edema along the superficial band of the medial collateral ligament may simply be secondary to underlying medial compartment pathology. There is increased signal intensity within the meniscofemoral ligament of Wrisberg which may reflect degeneration. EXTENSOR MECHANISM: The extensor mechanism is intact. There is edema within the subcutaneous fat anterior to the patellar tendon that is nonspecific.ADDITIONAL
