16-year-old woman with detached femoral bone plug. Anteroposterior (A) and lateral (B) views of the left knee. A rectangular fragment of bone is projected over the femoral notch on both views (black arrows). This bone fragment has become detached from the metal endobutton at the top of the femoral tunnel and has migrated down into the intercondylar notch. Lucencies in the patella (white open arrow) and tibial tuberosity (black arrowheads) are noted representing bone-patellar tendon-bone autograft harvest sites. The bio-absorbable interference screw is noted in the tibial tunnel (white arrows).
