关节镜下可吸收螺钉固定腘绳肌腱重建膝后交叉韧带

Arthroscopic reconstruction of posterior cruciate ligament with autogenous hamstring tendons fixed by bioabsorbable scews

目的探讨关节镜下可吸收螺钉固定四股腘绳肌腱单束重建膝关节后交叉韧带(PCL)的手术方法和疗效。方法自2005年2月～2008年5月对13例经临床及关节镜检查确诊为PCL断裂患者行关节镜下自体四股腘绳肌腱单束重建后交叉韧带、生物可吸收螺钉挤压固定术。结果 13例均获得随访,时间为13～39个月,平均26个月,Lyshlom评分由术前(45.23±3.45)分提高到(85.54±4.41)分(P<0.01)。结论关节镜下可吸收挤压螺钉固定自体四股腘绳肌单束重建PCL创伤小,定位准确,术后关节功能恢复满意,疗效可靠。

Objectives To evaluate the method and efficacy of arthroscopic reconstruction of posterior cruciate ligament （PCL） with quadrupled hamstring tendons fixed by bioabsorbable screws.Methods13 cases with PCL tear were diagnosed by clinical and arthroscopic examination from February 2005 to May 2008, Arthroscopic reconstruction of PCL with single bundle of quadrupled hamstring tendons was conducted and fixed by bioabsorbable screws.Results13 patients were followed up for13 months to 39 months （26 months on average）, The Lyshlom scores were improved from （45.23 ± 3.45） preoperatively to （85.54 ± 4.41） postoper-atively （P〈0.01）.ConclusionsSingle bundle reconstruction of PCL with quadrupled hamstring tendons fixed by bioabsorbable screws were excellent methods with less injuries, precise location, and early postoperative rehabilitation execise.
