Right knee pain. Evaluate meniscal tear. MENISCI: There is extensive degenerative tearing of the lateral meniscus. This includes attenuation, deformity and extrusion of the body of the lateral meniscus, attenuation and abnormal signal intensity of the anterior horn, and horizontally oriented signal abnormality within the posterior horn that extends to the tibial articular surface. There is increased signal intensity within the posterior horn of the medial meniscus indicating intrasubstance degeneration, which extends to the tibial articular surface suggesting a degenerative undersurface tear.ARTICULAR CARTILAGE AND BONE: There is full-thickness cartilage loss along the lateral femoral condyle and medial tibial plateau with cyst formation and degenerative signal abnormality in the underlying subchondral bone. There is more focal near-full-thickness to full-thickness degeneration of the articular cartilage along the lateral aspect of the medial femoral condyle. There is edema-type signal within the posterior aspect of the medial femoral condyle as well as a cyst in the anterior aspect of the medial tibial plateau which I suspect are degenerative etiology as well. Moderate cartilage degeneration affects the patellofemoral joint. There are tricompartmental osteophytes.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1.Osteoarthritis as described above most severely affecting the lateral tibiofemoral compartment with extensive tearing of the lateral meniscus.2.Intrasubstance degeneration and degenerative undersurface tearing of the medial meniscus as above.
