关节镜下联合应用Rigidfix、Endobutton和Intrafix系统固定腘绳肌腱重建前交叉韧带

背景：关节镜下前交叉韧带重建是治疗膝关节前交叉韧带损伤的金标准,但在肌腱的固定方式方面仍有分歧。目的：观察联合运用Rigidfix、Endobutton和Intrafix系统在关节镜下进行自体腘绳肌腱重建前交叉韧带的临床效果。方法：选取2009-05/2010-05在郑州大学第一附属医院关节外科应用Rigidfix、Endobutton和Intrafix系统行关节镜下自体腘绳肌腱重建前交叉韧带的患者30例,该组患者关节镜下均证实为膝关节前交叉韧带损伤断裂。其中男22例,女8例,年龄16~45岁。将患者股骨端用Endobutton、Rigidfix固定,胫骨端用Intrafix固定,观察术后近期疗效,以Lysholm评分、IKDC评分评价膝关节功能。结果与结论：对30例患者随访5~17个月（平均12个月）,随访期间无严重并发症发生,所有患者患膝关节活动度正常,平均Lysholm评分和IKDC评分分别由术前的（50.0±6.0）分和（49.5±5.5）分提高到术后的（85.5±3.5）分和（87.0±2.5）分（P〈0.05）。说明联合应用Rigidfix、Endobutton和Intrafix系统进行自体腘绳肌腱重建前交叉韧带的方法具有近期疗效佳、移植物固定可靠、并发症少等优点,能够达到良好的临床康复效果。

Rigidfix and Endobutton femoral fixation device,Intrafix tibial fixtaion device in arthroscopic reconstruction of anterior cruciate ligament using autografts of hamstring tendon

BACKGROUND：Arthroscopic reconstruction of anterior cruciate ligament（ACL）is the golden standard for injured anterior cruciate ligament.However,it remains controversial in tendon fixation pattern.OBJECTIVE：To evaluate clinical effects of arthroscopic ACL reconstruction by using hamstring autograft with femoral fixation via Rigidfix,Endobutton system and tibial fixation via Intrafix system.METHODS：Thirty cases of patients were chosen from Department of Joint Surgery,First Affiliated Hospital of Zhengzhou University（2009-05 to 2010-05）,which had been treated with arthroscopic ACL reconstruction by using hamstring autograft with femoral fixation via Endobutton,Rigidfix system and tibial fixation via Intrafix system.They all had been identified as ACL injure or ligament ruptures in arthroscopy.They were in a age range of 16 to 45,and twenty-two males with eight females.The femoral fixation was via Endobutton,Rigidfix system and tibial fixation via Intrafix system.The short-term effectiveness was observed postoperatively and knee function was evaluated by Lysholm and IKDC systems.RESULTS AND CONCLUSION：All 30 patients were followed up for 5-17 months（12 months on average）,during when there were no severe complications and all injured knee-joints were with a normal mobility.Lysholm and IKDC systems showed that the scores ascended respectively from（50.0±6.0） before surgery to（85.5±3.5） and（49.5±5.5） to（87.0±2.5）（P 0.05）.These all indicates that this method of Rigidfix and Endobutton femoral fixation device,Intrafix tibial fixtaion device in arthroscopic reconstruction of ACL using autografts of hamstring tendon owns many advantages such as good short-term effectiveness,reliable graft fixation and less complications,which gets a good clinical recovery effectiveness.
