Editorial Commentary: Revision of Failed Double-Bundle Anterior Cruciate Ligament Reconstruction

Double-bundle (DB) reconstruction of the anterior cruciate ligament was favored for several years. However, recent studies increasingly show that this technique does not provide a clear advantage over the less-invasive single-bundle technique. Unfortunately, the graft fails relatively often after ACL reconstruction. Postoperative communication of the bone tunnels through bone tunnel widening is possible. Since 2 drill channels are created in the DB technique, femoral as well as tibial, it is assumed that this technique may cause problems during revision. So, in part, revision may require a 2-step procedure with bone graft filling of the tunnels as the first step. It is important that surgeons with experience using DB publish their revision strategies and experiences.
