We investigated the effects of graft linkage material on range of motion, anterior instability, and bone tunnel enlargement on 37 knees in 37 patients who underwent ACL reconstruction using hamstring autograft at one year postoperatively. The knees were divided into three subgroups depending on the graft materials and fixation techniquesuged; In Group A (15 knees), the fixation technique using Endobutton® and Tefron tape® was applied to the femoral side, while post screw with #5 Ethibond was used on the tibial side. In Group B (7 knees), endobutton fixation using 2.5mm wide Telos artificial ligament® was applied to the femoral side with the same fixation as Group A to the tibial side. In Group C (15 knees), the same fixation as Group B was applied to the femoral side and fixation with double staples using 3mm width Telos artificial ligament® to the side. There were no significant differences in the postopertive range of motion between the three groups, although anterior instability in Group B was smaller than that in Group B and Group C. However, the incidence and amount of bone tunnel enlargement in the coronal plane on the femoral side in Group A was larger than those of the other two groups, but there was no difference in those on the tibial side.
