Reason: eval knee History: pain MENISCI: There is intrasubstance degeneration of the medial meniscus with mild surface irregularity of the posterior horn suggesting surface fraying, but we see no fluid-filled tear. There is intrasubstance degeneration of the lateral meniscus particularly involving the body and posterior horn. Within the posterior horn, this signal extends to the tibial articular surface likely representing degenerative undersurface tearing. Furthermore, there is extensive signal abnormality within the root of the lateral meniscus likely representing extensive degenerative tearing. There is increased signal within the body of the meniscus extending to the free edge likely representing additional degenerative tearing. The anterior horn appears relatively spared.ARTICULAR CARTILAGE AND BONE: There is severe degeneration of the articular cartilage of the patella with large areas essentially devoid of cartilage, particularly along the lateral facet. There is also full-thickness loss of the articular cartilage of the femoral trochlea, particularly along the lateral facet, with subchondral cyst formation and edema within the underlying subchondral marrow. There is near full-thickness cartilage loss along the lateral tibial plateau posteriorly, with underlying subchondral cyst formation as well as moderate degeneration of articular cartilage of the lateral femoral condyle. There is relatively mild degeneration of the articular cartilage of the medial compartment.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Osteoarthritis most severely affecting the patellofemoral joint.2. Degenerative tearing of the lateral meniscus with relatively mild degeneration/fraying of the medial meniscus.3. Joint effusion, Baker's cyst, and other findings as described above.
