Endobutton钢板及Rigidfix横穿钉固定自体腘绳肌腱重建前交叉韧带

背景：Endobutton的钢板设计和Rigidfix的横穿钉优点使之较广泛地在前交叉韧带重建中应用。目的：比较分析自体腘绳肌腱行前交叉韧带单束重建过程中Endobutton和Rigidfix系统的效果差异。方法：选取2007-04/2009-06运用Endobutton系统和Rigidfix-Intrafix系统行自体腘绳肌腱单束重建前交叉韧带各30例患者,重建前分别记录前抽屉试验、Lachman试验、轴移试验结果及Lysholm膝关节评分。由同一术者按两种方案分别重建前交叉韧带后,进行正规康复锻炼。重建后定期随访并由同一人记录随访指标,与重建前指标进行对比分析,评价两组患者症状的改善程度。结果与结论：Endobutton组患者经过6～26个月的随访,Lysholm膝关节评分由重建前（56.6±5.9）分增长到重建后（91.4±4.0）分。经t检验,差异有显著性意义（P〈0.05）。Rigidfix组患者经过6～24个月的随访,Lysholm膝关节评分由重建前（59.2±6.4）分增长到重建后（93.1±4.7）分,经t检验,差异有显著性意义（P〈0.05）。Endobutton组与Rigidfix组重建后Lysholm膝关节评分差异无显著性意义（P〉0.05）。经过分析,并不能得出其中某一套系统强于另一套系统的结论。它们各自均有独特的优势,同时又不能互相取代。

Endobutton CL versus Rigidfix fixation systems for fixation of autologous quadrupled hamstring tendon in anterior cruciate ligament reconstruction

BACKGROUND：Endobutton CL and Rigidfix system are widely used in anterior cruciate ligament （ACL） reconstruction.OBJECTIVE：To retrospectively evaluate and compare clinical results between Endobutton CL and Rigidfix fixation systems after ACL reconstruction with autologous quadrupled hamstring tendons.METHODS：Thirty patients that were treated with arthroscopic ACL reconstruction respectively using hamstring autograft with EndoButton CL system and Rigidfix fixation systems from April 2007 to June 2009 were selected.Patients were evaluated by the anterior drawer test,Lachman test,Pivot shift test,and Lysholm score.ACL reconstruction was performed by one doctor,followed by rehabilitative exercise.The patients were followed up and the follow-up indexes were recorded and compared with preoperative indexes to evaluate improvement of two groups.RESULTS AND CONCLUSION：The follow-up period of EndoButton CL group was 6 to 26 months,and Lysholm scores were increased from preoperative （56.6±5.9） to postoperative （91.4±4.0）,which showed significant differences in t-test （P0.05）.The follow-up period of Rigidfix group was 6 to 24 months,and Lysholm scores were increased from preoperative （59.2±6.4） to postoperative （93.1±4.7）,which showed significant differences in t-test （P0.05）.There were no significant differences in postoperative Lysholm scores between two groups （P0.05）.Results demonstrated that Rigidfix and Endobutton fixation device have specific advantages in ACL reconstruction.
