关节镜下Endobutton联合intrafix固定自体腘绳肌腱重建ACL的疗效分析

Effects of arthroscopic Endobutton combined with intrafix fixation with autologous hamstring tendon on ACL reconstruction

目的观察关节镜下Endobutton联合intrafix固定自体腘绳肌腱重建前交叉韧带的疗效。方法 80例本院收治的需行自体腘绳肌腱重建前交叉韧带患者入选本研究,按照配对分组法分为两组,观察组采取关节镜下Endobutton联合intrafix固定自体腘绳肌腱重建前交叉韧带,对照组采取可吸收挤压螺钉固定,术后24个月时比较两组效果。结果术前两组Lysholm和IKDC评分比较无统计学差异(P>0.05);术后24个月时,两组Lysholm和IKDC评分均显著升高(P<0.05),而观察组的升高幅度均大于对照组(P<0.05);观察组术后并发症发生率(7.5%)显著低于对照组(25.0%)(P<0.05)。结论关节镜下Endobutton联合intrafix固定自体腘绳肌腱重建前交叉韧带的疗效较佳,术后膝关节功能更优,且术后并发症发生率低,具有重要临床价值。

Objective To observe the effects of arthroscopic Endobutton combined with intrafix fixation with autologous hamstring tendon on arthroscopic cruciate ligament （ACL）. Methods A total of 80 patients admitted to our hospital for autologous hamstring tendon anterior cruciate ligament reconstruction were selected and divided into two groups according to the matched samples： the observation group was treated with arthroscopic Endobutton combined with intrafix fixation with autologous hamstring tendon on ACL reconstruction; the control group was treated with absorbable interference screw fixation. The effects in two groups were compared 24 months after the operation. Results The preoperative Lysholm and IKDC scores in the two groups showed no significant statistical difference（P 〉 0.05）; 24 months after the operation, the Lysholm and IKDC scores in the two groups increased significantly（P 〈 0.05）, but the scores in the observation group increased more than those in the control group（P 〈 0.05）. The incidence（7.5%） of postoperative complications in the observation group was significantly lower than that （25.0%） in the control group （P 〈 0.05）. Conclusion The arthroscopic Edobutton combined with intrafix fixation with autologous hamstring tendon has better effects on ACL reconstruction, significantly better postoperative recovery of knee joint functions and lower incidence of postoperative complications, thus it has important clinical value.
