Medial Meniscus Bucket Handle Tear - MSK Radiology Imaging Findings: • Truncation of the medial meniscus on the coronal sequence. • Mesial displacement of the meniscal fragment into the intercondylar notch. The "double PCL sign" is seen on the Sagittal with the displaced meniscal fragment parallel to the PCL. • The displaced fragment is also seen on the axial with visualization of the anterior and posterior attachment points. Case description: • Bucket Handle Tear is an extensive vertical longitudinal meniscus tear with mesial displacement of the free edge fragment toward (or into) the intercondylar notch. • Usually maintains anterior/posterior attachments. • Displaced fragment usually DOES NOT spontaneously reduce. • Repair if tear in peripheral red zone of the vascular meniscal tissue (3-5 mm from periphery). Differential diagnosis: • Displaced flap tear of meniscus: not attached to anterior/posterior meniscus. • Intra-articular body: Chondral/osteochondral fragment may migrate to intercondylar notch. • Meniscofemoral ligament: extends from posterior horn lateral meniscus to intercondylar notch.
