This study tells us about the anatomy of the Anterior Cruciate Ligament, the biomechanical aspects of ACL reconstruction, review the outcomes of single bundle ACL reconstruction and present the current techniques for anatomic single bundle reconstruction. A critical evaluation of ACL reconstruction techniques has revealed that single-bundle grafts that were placed by conventional trans-tibial drilling do not provide adequate restraint to translational and rotatory forces. In some knees, this will affect function and possibly contribute to further chondral injuries.
