Reason: r knee pain History: pain MENISCI: There is marked deformity and blunting of the posterior horn and body of the lateral meniscus indicating a combination of degeneration and complex degenerative tearing which extends to involve the free edge of the meniscus as well as anterior horn of the meniscus. There is globular increased signal abnormality within the posterior horn of the medial meniscus indicating intrasubstance degeneration. Some of this signal extends to the femoral articular surface indicating superficial fraying.ARTICULAR CARTILAGE AND BONE: There is full-thickness articular cartilage degeneration along the weightbearing surface of the lateral femoral condyle and lateral tibial plateau about the posterior horn of the meniscus with large areas completely devoid of articular cartilage. There is a focal near full-thickness articular cartilage degeneration along the weightbearing surface of the medial femoral condyle. There is subjective thinning of the articular cartilage of the patellofemoral articulation. There are focal areas of full-thickness articular cartilage degeneration along both the medial and lateral facet of the patella. There are tricompartmental osteophytes.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Osteoarthritis of the knee with full-thickness articular cartilage degeneration most pronounced along the lateral tibiofemoral compartment.2. Complex degenerative tearing of the lateral meniscus. Intrasubstance degeneration and superficial fraying of the posterior horn of the medial meniscus.3. Baker's cyst and loose body within the joint. Other findings as described above.
