Abstract:

目的探讨关节镜下跨后纵膈入路自体腘绳肌腱保残单束重建后交叉韧带(posterior cruciateligament,PCL)的手术方法及临床疗效。 方法2010年6月-2014年4月采用关节镜下跨后纵膈入路自体腘绳肌腱保残单束重建PCL治疗57例单纯PCL断裂患者。男41例,女16例;年龄19~42岁,平均27.7岁。均有明确外伤史。术前后抽屉试验Ⅱ度阳性9例,Ⅲ度阳性48例。受伤至手术时间2周~25个月,平均13个月。采用Lysholm评分及膝关节活动度评价术后膝关节功能。 结果手术均顺利完成,术中未发生血管、神经损伤等,术后切口均Ⅰ期愈合,无感染等早期并发症发生。57例均获随访,随访时间12~20个月,平均16.6个月。末次随访时伸膝活动度正常,屈膝120~130°,达到了正常运动生活活动范围。末次随访时所有患者MRI示重建韧带连续性良好并达腱-骨愈合;Lysholm评分总分较术前显著改善,差异有统计学意义(t=-27.429,P=0.000)。 结论关节镜下跨后纵膈入路自体腘绳肌腱保残单束重建PCL手术操作安全简便,肌腱固定牢靠,近期效果满意
