Endobutton femoral fixation for hamstring anterior cruciate ligament reconstruction: Surgical technique and results

The technique for endobutton femoral fixation of double semitendinosus/double gracilis hamstring anterior cruciate ligament (ACL) reconstruction is described. Two- to 8-year follow up of 139 primary ACL reconstructions in skeletally mature patients found 86% IKDC normal stability and 97% ≤3 mm KT 1000 side-to-side stability rates. No knee had 5 mm or greater differences. There were no graft failures and no clinical knee instability. No endobutton lost position. There were no deep knee infections or hardware-related complications. Endobutton femoral fixation produced high levels of knee stability with no hardware-related complications.
