Abstract

PURPOSE: We aimed to compare cross-pin fixation and Endobutton femoral fixation for hamstring anterior cruciate ligament (ACL) reconstruction with respect to clinical and radiographic results, including tunnel widening and the progression of knee osteoarthritis (OA). MATERIALS AND METHODS: Between August 2002 and August 2005, 126 autogenous hamstring ACL reconstructions were performed using either cross pins or Endobutton for femoral fixation. Fifty-six of 75 patients in the cross-pin group and 35 of 51 patients in the Endobutton group were followed up for a minimum of 4 years. We compared the clinical and radiological results between the groups using the International Knee Documentation Committee (IKDC) evaluation form, the KT-2000 arthrometer side to side difference, the amount of tunnel widening and the advancement of OA on radiographs. RESULTS: There were no significant differences in the IKDC grades between the groups at the 4 year follow-up. There was no significant difference in the side to side difference according to KT-2000 arthrometer testing. Also, there were no significant differences in terms of tunnel widening or advancement of OA on radiographs. CONCLUSIONS: Endobutton femoral fixation showed good results that were comparable to those of cross pins fixation in hamstring ACL reconstruction.
