Reason: Med Men Tear History: Pain MENISCI: There is globular increased signal abnormality within the anterior horn of the lateral meniscus indicating intrasubstance degeneration. Some of the signal extends to the femoral articular surface indicating superficial fraying/degenerative tearing. The posterior horn appears intact. There is globular increased signal abnormality within the posterior horn of the medial meniscus indicating intrasubstance degeneration. There is blunting of the body of the medial meniscus indicating degenerative tearing. No fluid-filled tear is evident.ARTICULAR CARTILAGE AND BONE: The medial compartment articular cartilage appears intact. There is full-thickness articular cartilage degeneration along the lateral femoral condyle anterior to the anterior horn of the meniscus. There is full-thickness articular cartilage degeneration affecting the patellofemoral joint particularly along the lateral facet of the patella which is nearly completely devoid of articular cartilage. There is focal full-thickness articular cartilage degeneration along the lateral facet of the femoral trochlea, inferiorly, with underlying subchondral cyst formation and degenerative signal abnormality. There are tricompartmental osteophytes.LIGAMENTS: The cruciate and collateral ligaments appear intact. There is increased signal abnormality and thickening of the proximal fibers of the lateral collateral ligament proper which may reflect prior injury or sprain. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Intrasubstance degeneration and superficial fraying/degenerative tearing of the menisci without evidence of an unstable fluid-filled tear.2. Osteoarthritis of the knee including full-thickness articular cartilage degeneration most pronounced along the patellofemoral articulation as described above.3. Increased signal abnormality within the lateral collateral ligament proper may reflect a mild sprain in the correct clinical setting.
