We developed the technique of anatomical, rectangular tunnel anterior cruciate ligament (ACL) reconstruction with a single bone-patellar tendon-bone (BPTB) graft, based on the concept of the double-bundle (DB) reconstruction using soft tissue grafts including hamstring tendons. This technique mimics the natural, or anatomical, arrangement of the native ACL fibers. This technique has the following advantages: 1) creation of a DB ACL reconstruction with a single BPTB graft; 2) maximization of graft-tunnel contact area; 3) containment of the tunnel apertures within the anatomic ACL attachment footprint; 4) rotational control of the graft within the tunnels during and after fixation; and 5) preservation of notch anatomy. This video demonstrates: 1) strict ACL footprints along with histological evidences; 2) how to visualize the footprints /attachment areas; 3) how to create the tunnel apertures within the anatomic ACL attachment footprints with the newly developed instruments; and 4) how to properly place and fix the grafts with notch anatomy preserved.
