However, there are a few fixture researches on the expansion of bone tunnel and graft changes. OBJECTIVE: To observe the short-period effect of femoral tunnel side fixtures Endobutton and Tightrope used in autologous hamstring anterior cruciate ligament reconstruction on bone tunnel and implant change. METHODS: Twenty-three patients with anterior cruciate ligament injuries received one-stage hamstring reconstruction, including 13 cases of femoral tunnel fixation with Endobutton and 10 cases with Tightrope. Tibial tunnel used extrusion screws. We observed operation time, recent effects after operation (Lysholm knee score, IKDC score) and the postoperative change of femoral tunnel diameter and graft length. RESULTS AND CONCLUSION: (1) Twenty-three cases were followed up for 912 months, averagely 10 months. (2) Joint motion was not limited in both groups. No significant difference in IKDC and Lysholm scores was determined between the two groups (P > 0.05). (3) Graft length and femoral tunnel diameter were significantly higher in the Endobutton group during final follow-up compared with that at 1 week postoperatively (P < 0.05). (4) These results suggested that the recent effects were similar between Tightrope and Endobutton fixation, but Tightrope fixation device reduces the length of graft and the extent of bone tunnel enlargement.
