Reason: L knee meniscus tear History: L knee pain MENISCI: There is a branching linear signal abnormality within the posterior horn of the medial meniscus extending to both the tibial and femoral articular surfaces indicating a complex tear with both horizontal and vertical components predominantly involving the inner half of the posterior horn. Signal abnormality extending into the body of the medial meniscus suggests intrasubstance degeneration. The anterior horn appears normal. The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is mild degeneration of the articular cartilage of the patellofemoral joint with underlying small subchondral cyst formation. A small full-thickness low intensity focus is also seen in the articular cartilage of the trochlea with underlying cyst formation. There is mild degeneration of the articular cartilage of the medial tibiofemoral compartment with mild edema type signal in the medial tibial plateau, which is presumably degenerative.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Medial meniscal tear as described above.2. Mild osteoarthritis as described above.
