Simple solution for failure of trailing sutures when using the EndoButton in anterior cruciate ligament reconstruction: the "Rescue Rein".

In this article, we introduce the technique of adding a second suture in the distal hole of the EndoButton. This suture, the "Rescue Rein," is kept with the graft and is a simple solution for recovering the graft during anterior cruciate ligament reconstruction when the EndoButton becomes jammed within the femoral tunnel and the trailing sutures cannot be removed.
