摘　　要：背景:Endobutton因其优点已在临床中广泛应用,其不足也在逐渐被认识。Tightrope的优点克服了Endobutton的不足,已逐渐被运动创伤医生所接受。目的:分析比较Tightrope与Endobutton在前交叉韧带重建内固定中应用效果的差异。方法:选择60例前交叉韧带断裂者在关节镜下进行重建,随机分配30例韧带由同一位术者重建中应用Endobutton装置重建,另30例韧带重建采用Tightrope装置(改进的Endobutton固定系统)重建。内固定后正规功能锻炼,定期随访,评估各项指标进行对比,评价Tightrope与Endobutton在交叉韧带重建内固定中应用效果优劣。结果与结论:前交叉韧带重建中Tightrope内固定较Endobutton内固定可减少操作时间,减小取腱切口处长度,并能减少股骨侧骨道骨量的丢失。内固定后3,6个月两组患者在膝关节最大屈曲度,膝关节评分,Tegner运动水平评分3方面比较,差异无显著性意义。结果提示Tightrope固定系统在前交叉韧带重建过程中,操作更简单,方便,骨量丢失少。内固定后6个月随访中,两者的临床疗效相当,无优与劣之分。BACKGROUND： Because of its advantages, Endobutton has been widely used in clinic. Currently, its shortcomings are increasingly recognized. Tightrope that overcomes the shortcomings of Endobutton has been gradually accepted by a doctor skilled in sports injuries.OBJECTIVE： To analyze and compare the differences in the effects of Tightrope and Endobutton in the reconstruction of the cruciate ligament. METHODS： Totally 60 cases of anterior cruciate ligament rupture were selected and subjected to anterior cruciate ligament reconstruction under arthroscopy, of which 30 cases were randomly assigned to reconstruction by Endobutton device and 30 cases underwent reconstruction by Tightrope device. All operations were performed by the same surgeon. All patients were subjected to regular functional exercise and were followed up regularly after operation. Effects of Tightrope and Endobutton in the cruciate ligament reconstruction were evaluated by comparing various indexes in the two groups. RESULTS AND CONCLUSION： Compared to the Endobutton fixation system, the Tightrope fixation system could shorten the operation time, reduce the length of tendon incision, and decrease the loss of bone mass in the femoral bone tunnel. There were no significant differences in the maximum knee flexion, knee joint score and Tegner movement level score between the two groups at 3 and 6 months after operation. These findings indicate that the Tightrope fixation system is superior to the Endobutton fixation system, because it is more simple and convenient to operate and has less bone loss. However, their clinical efficacy has no difference after 6 months.
