Persistent knee pain MENISCI: There is abnormal signal intensity within the posterior horn of the medial meniscus with extension to the tibial articular surface suggesting an undersurface tear, perhaps with an unstable horizontal flap component. This tear extends into the body of the meniscus where meniscal flounce is noted. The anterior horn of the medial meniscus is intact.There is mild intrasubstance degeneration of the lateral meniscus but no evidence of tear.ARTICULAR CARTILAGE AND BONE: There is partial-thickness degeneration of the articular cartilage of the patella. There is minimal degeneration of the articular cartilage of the medial and lateral compartments, commensurate with the patient's age. There is serpentine signal abnormality within the proximal tibial metaphysis consistent with a chronic bone infarct.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: The quadriceps and patellar tendons are normal. There is edema within the quadriceps fat pad which is of uncertain clinical significance.ADDITIONAL
Medial meniscal tear with other findings described above.
