摘要(Abstract)：
[目的]评估关节镜下四股腘绳肌腱单束重建膝后交叉韧带(PCL)的技术和效果。[方法]自2001年4月~2004年10月,49例病人(49膝)经关节镜检查证实为PCL断裂,其中13膝伴前交叉韧带断裂,14膝伴后外侧角损伤,6膝伴后内侧角损伤,9膝伴外侧半月板破裂,5膝伴内侧半月板损伤,2例伴动脉损伤,4例伴腓总神经损伤。均于关节镜下行自体四股绳肌腱单束PCL重建术,采用Bionx生物可吸收挤压螺钉或钛挤压螺钉解剖位固定重建韧带。[结果]本组术后早期均未发生严重并发症。术后随访10~52个月,平均22个月,Lysholm膝关节功能评分由术前30~60分(平均47.96分),提高至随访时70~95分(平均89.08分)(P<0.01)。国际膝关节文件编制委员会(IKDC)综合评定由术前异常(C级)10例、显著异常(D级)39例,改进为随访时正常(A级)20例、接近正常(B级)24例、异常(C级)5例(P=0.0000)。49例患者中,40例恢复伤前运动水平,9例运动水平较伤前减低。[结论]关节镜下自体四股绳肌腱单束重建膝PCL创伤小、手术操作简捷,术后膝关节功能恢复满意。
