Reason: Assess for meniscal tear - h/o pain with deep squat and mechanical locking of knee History: Knee pain and mechanical symptoms MENISCI: The medial and lateral meniscus appear intact. There is increased signal abnormality within the posterior horn of the lateral meniscus indicating mild intrasubstance degeneration.ARTICULAR CARTILAGE AND BONE: The medial and lateral compartment articular cartilage appear relatively spared. There is full-thickness articular cartilage degeneration along the lateral facet of the patella with large areas completely devoid of articular cartilage. There is underlying subchondral signal abnormality. There is focal full-thickness articular cartilage degeneration along the lateral facet of the femoral trochlea as well.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact. There is intermediate signal intensity within the patellar tendon which may reflect mild tendinosis.ADDITIONAL
Articular cartilage degeneration and full thickness defects affecting the patellofemoral articulation. The menisci appear intact.
