Reason: lateral meniscal tear? History: continued lateral pain with reduced ROM to extension 1 month after injury MENISCI: The lateral meniscus is abnormal. The anterior horn appears unusually large and the body appears unusually small with extensive increased signal intensity within its substance. There is also vertically oriented increased signal intensity at the junction of the body and anterior horn of the lateral meniscus. An additional obliquely oriented signal abnormality is seen within the junction of the body and posterior horn of the lateral meniscus. These findings suggest a complex tear likely with a displaced flap fragment. The medial meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is mild subchondral edema within the patella along the lateral facet with mild heterogeneity of the overlying cartilage, which may reflect mild degeneration.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Complex tear of the lateral meniscus.2. Mild focal degeneration of the articular cartilage of the patella.3. Joint effusion.
