Case:
We report a rare case of early postoperative migration of an EndoButton following anatomic double-bundle anterior cruciate ligament reconstruction with use of the EndoButton for femoral fixation. Although secure fixation of the EndoButton was confirmed during the operation, one-week postoperative radiographs revealed an intratunnel displacement of the posterolateral EndoButton. We performed a reoperation and refixed the EndoButton to the surface of the femoral cortex; we also hooked and tied both ends of the sutures to make a knot in order to prevent remigration.
Conclusion:
Orthopaedic surgeons should be aware that EndoButton displacement and migration could arise at an early postoperative stage.
