Abstract:
Anterior cruciate ligament (ACL) injuries are common to athletes and non-athletes alike. Whereas the literature has historically supported bone-patellar tendon-bone as the gold standard for active patients who elect to undergo ACL reconstruction, other studies have suggested that soft-tissue grafts do not increase the risk of rerupture. Because graft diameter has a direct effect on revision rates, we share a technique for all-inside ACL reconstruction using quadrupled semitendinosus and gracilis autograft that allows for a predictable, robust graft. Reproducible steps of graft harvesting, tunnel preparation, graft passage, and fixation are shared to achieve a robust anatomic reconstruction.
