摘　　要：目的探讨关节镜下应用Rigidfix和Intrafix系统固定同种异体胫前肌重建膝关节前交叉韧带的临床效果。方法2010年1月至2011年12月在关节镜下应用同种异体胫前肌重建前交叉韧带21例，2l例均采用Rigidfix和Intrafix系统固定同种异体胫前肌，术后进行系统的康复治疗并处理相应并发症，术后随访6-12月，按照Lysholm膝关节评分评价疗效。结果本组21例均获得随访，21例患者均未发生严重并发症，均未发生排斥反应，术后6月复查均无乙肝及HIV等疾病传播。膝关节屈曲均达120。及以上，伸直0°，前抽屉试验19例阴性，2例I度阳性，所有患者均无膝关节不稳的主观症状。Lysholm膝关节评分由术前的平均（32．2±4．2）分提高至平均（88．2±3．6）分，差异有统计学意义（P〈0．05）。结论关节镜下应用Rigidfix和Intrafix系统固定同种异体胫前肌重建膝关节前交叉韧带临床效果良好，避免患者应用自体肌腱所产生的自体损伤，固定牢固，术后膝关节稳定性良好。Objective To study the clinical effect ofarthroscopic reconstruction of anterior cruciate ligament using Rig- idflx and Intraflx system with allograft tibialis anterior tendons. Methods 21 anterior cruciate ligaments rupture were re- constructed arthroscopically with allograft tibialis anterior tendons, all graft were fixed with Rigidfix and Intrafix system. Patients were treated with systematic rehabilitation therapy and relevant complications were managed postoperatively. All patients were followed up for 6-12 months, Lysholm rating were managed to evaluate clinical results. Result All patients were followed up for 6-12 months postoperatively and no serious complications were found, no rejection reaction, no HBV and HIV infection after 6 months. All patients achieve knee flexion above 120~, no extension lag, anterior drawer test negative 19 cases, positive 2 case with I degree. All patients had no sensation of knee instabilization. The Lysholm score increased from 32.2±4.2 to 88.2±3.6, the difference was significant （P〈0.05）. Conclusion Arthroscopic recon- struction of anterior cruciate ligament using Rigidfix and Intraflx system with allograft tibialis anterior tendons can achieve good clinical outcomes, avoid the damages to the patients when use autograft tendons, firm fixation, good stabilization after operation.
