Reason: eval for meniscal tear History: R knee pain/effusion s/p fall MENISCI: There is increased signal intensity within the inner half of the posterior horn of the medial meniscus, just medial to the root of the meniscus, likely representing degenerative fraying, but we see no fluid-filled or otherwise unstable tear. There is globular signal within the lateral meniscus, particularly the body of the meniscus, suggesting intrasubstance degeneration, but we see no definite tear. ARTICULAR CARTILAGE AND BONE: There is mild to moderate degeneration of the articular cartilage of the patella, particularly along the median eminence and extending into the cartilage of the lateral facet with superficial fissuring. There is moderate to severe degeneration of the articular cartilage of the femoral trochlea with full-thickness defects and subchondral cysts particularly along the lateral facet. There is full-thickness delamination of the articular cartilage of the weightbearing portion of the medial femoral condyle just anterior to the posterior horn of the medial meniscus. There is a focal full-thickness cleft of the articular cartilage of the lateral femoral condyle just above the periphery of the posterior horn of the lateral meniscus with mild to moderate degeneration of the articular cartilage of the lateral femoral condyle more anteriorly. There are small osteophytes.LIGAMENTS: The cruciate and collateral ligaments appear intact. Edema along the MCL could represent a sprain in the correct clinical context. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Mild degenerative fraying of the free edge of the posterior horn of the medial meniscus, but we see no discrete meniscal tear.2. Tricompartmental articular cartilage degeneration most severely affecting the femoral trochlea.3. Edema along the MCL could represent a sprain in the correct clinical context.4. Small joint effusion and Baker's cyst.
