Pain, question lateral meniscal tear. MENISCI: There is horizontal increased signal intensity within the body and posterior horn of the lateral meniscus indicating intrasubstance degeneration. The signal extends to the tibial articular surface indicating an undersurface horizontal tear. The anterior horn of the lateral meniscus is intact. There is fraying of the free/inner edge of the posterior horn of the medial meniscus without discrete tear. ARTICULAR CARTILAGE AND BONE: There is diffuse degeneration of the articular cartilage of the patella with full-thickness cartilage loss along the median eminence. There is perhaps mild fraying of the articular cartilage of the lateral compartment. Bone marrow signal is within normal limits. No fracture or contusion.LIGAMENTS: ACL, PCL, LCL and MCL are intact. EXTENSOR MECHANISM: Quadriceps and patellar tendons are intact.ADDITIONAL
1. Intrasubstance degeneration and horizontal tear of the posterior horn and body of the lateral meniscus.2. Cartilage degeneration most severely affecting the patella.
