Recent progress in the technique and instrumentation of arthroscopic knee surgery has allowed reconstruction of the two bundles separately to more closely mimic the normal structure of the ACL using hamstring tendons which function at different angles of flexion as in a double-bundle reconstruction. From reviewing studies that investigated the biomechanical aspects and the patient outcome studies of double-bundle (ACL) reconstruction technique, this essay highlights that different studies yielded varying results. Most reports describe surgical techniques in great detail; yet, they provide very little, if any data regarding objective clinical patient outcomes and when outcomes data are reported they are usually for less than a two-year post-operative period.
