背景：前交叉韧带重建中股骨隧道侧悬吊固定装置在临床上已有了一定的比较，但是关于固定装置对骨隧道扩大及对移植物变化的研究较少。 目的：观察自体腘绳肌重建前交叉韧带股骨隧道侧固定装置Endobutton及Tightrope对骨道及移植物变化的近期影响。 方法：对23例前交叉韧带断裂患者行一期自体腘绳肌重建，其中股骨隧道固定13例选用Endobutton，10例选用Tightrope，胫骨隧道均选用挤压螺钉。观察手术耗时、治疗后近期疗效(Lysholm、IKDC评分)、治疗后股骨骨隧道直径及股骨移植物长度的变化。 结果与结论：①23例均获随访，随访时间9-12个月，平均随访10个月；②两组患者关节活动均无明显受限，IKDC及Lysholm评分差异均无显著性意义(P>0.05)；③Endobutton组末次随访时移植物长度及股骨骨隧道直径显著高于治疗后1周，差异有显著性意义(P<0.05)；④结果表明，Tightrope与Endobutton 固定近期临床疗效相当，但Tightrope固定装置减小了移植物长度拉伸和骨隧道扩大的程度。%BACKGROUND:Femoral tunnel suspensory fixation device for anterior cruciate ligament reconstruction has a certain clinical comparison. 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 fol owed up for 9-12 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 fol ow-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.
