The MRI scan shows a displaced, bucket-handle lateral meniscus tear. The sagittal view shows the typical "large anterior horn" sign, or "double meniscus" sign in which the displaced bucket-handle fragment appears just anterior to the native anterior horn of the lateral meniscus. The presence of the fibula on the sagittal view confirms this as the lateral compartment. The image is lateral and the cruciate ligaments are not visualized. The articular cartilage shown does not demonstrate an osteochondral lesion.
