Reason: pain History: pain. MENISCI: There is linear increased signal intensity within the posterior horn of the medial meniscus that extends to the tibial articular surface that likely represents a horizontal degenerative tear. Additional degeneration within the substance of the body of the medial meniscus. Anterior horn appears normal.The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: Moderate to severe thinning of the articular cartilage of the medial facet of the patella with foci of full thickness degeneration and underlying small subchondral cyst. Articular cartilage of the lateral facet appears relatively well preserved. Subjectively, the articular cartilage of the femoral trochlea appears thinned. There is also minimal subjective thinning of the articular cartilage of the tibiofemoral articulations, essentially within normal limits for age.LIGAMENTS: The anterior cruciate ligament and posterior cruciate ligament are intact. The medial collateral ligament is intact. The lateral collateral ligament complex is intact. EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1.Degenerative horizontal undersurface tear of the posterior horn of the medial meniscus.2.Cartilage degeneration, most pronounced along the medial facet of the patella with relatively mild degeneration elsewhere.3.Baker's cyst.
