title: Intra-articular detachment of the Endobutton more than 18 months after anterior cruciate ligament reconstruction.
abstract: We report a case of detachment of an Endobutton (Acufex Microsurgical, Mansfield MA) used for femoral fixation of a reconstructed anterior cruciate ligament. The Endobutton, which was confirmed to be in place on the suprapatellar space of the femur by radiograph 18 months postoperatively, was found in the popliteal space by radiograph 25 months after surgery. This is a rare complication, but our case suggests that the Endobutton should not be fixed too distal close to the femoral groove.
