47-year-old male with knee pain. Evaluate lateral meniscus. MENISCI: The medial and lateral meniscus appear intact.ARTICULAR CARTILAGE AND BONE: There is focal degeneration of the articular cartilage of the patella along the medial and lateral facets involving greater than 50% of the cartilage thickness. The medial and lateral compartment articular cartilage appears relatively spared. There is a focus of low signal intensity in the anterior aspect of the femur likely representing a benign bone island.LIGAMENTS: The IT band appears slightly thickened with inflammation of the soft tissues between the IT band and the lateral femoral condyle, suggesting a "friction syndrome". The lateral collateral ligament proper and biceps femoris tendon appear intact. The ACL, PCL and MCL appear intact.EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. MR findings compatible with an IT band "friction syndrome". We see no meniscal tear.2. Degeneration of the articular cartilage of the patella as described above.
