Reason: knee instability History: rule out meniscal tear MENISCI: The medial meniscus appears normal. There is slight blunting of the free edges of the anterior and posterior horns of the lateral meniscus, which may reflect chronic attritional fraying/tearing or perhaps sequela of interval surgery, but the horizontal tear seen on the prior study is no longer evident. We see no fluid signal intensity within the lateral meniscus, to indicate an unstable tear. ARTICULAR CARTILAGE AND BONE: We see no fluid-filled cartilage defects. Bone marrow signal is normal.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: The patellar and quadriceps tendons are intact.ADDITIONAL
Slight blunting of the free edge of the lateral meniscus may reflect mild chronic attritional fraying/tearing or sequela of interval partial meniscectomy. We see no findings to suggest an unstable tear.
