关节镜下自体4股腘绳肌腱双束与单束重建前交叉韧带后膝关节稳定性及功能评分的meta分析

目的]评价关节镜下自体4股腘肌腱双束与单束重建前交叉韧带的临床效果.方法]计算机检索CENTRAL、PubMed、Embase、CBM等数据库,获取自体4股腘绳肌腱移植双束与单束重建前交叉韧带的随机对照试验,根据Cochrane协作网推荐的随机对照试验偏倚评估工具对纳入研究的方法学进行评估,并使用RevMan5.0对数据进行Meta分析.结果]共纳入10篇文献,693例前交叉韧带损伤患者纳入Meta分析,结果显示:双束重建组术后KT2000或KT1000测量值与单束重建组的差异有统计学意义(SMD=-0.27,95% CI(-0.53,-0.01),P=0.04);轴移试验阴性(RR=1.35,95% CI(1.16,1.56),P<0.000 1)、弱阳性(RR=0.37,95% CI(0.18,0.74),P=0.005)、阳性(RR =0.17,95% CI (0.06,0.66),P=0.01)的差异均有统计学意义.功能评分中IKDC主观评分(SMD=0.03,95% CI(-0.21,0.28),P=0.79)和Lysholm评分(SMD=-0.25,95% CI(-0.53,0.02),P=0.07)均无统计学意义.结论]自体4股腘绳肌腱双束重建前交叉韧带在恢复膝关节的前直向稳定性和旋转稳定性方面优于单束重建;但功能评分相似.

Knee stability and functional score after double-bundle versus single-bundle of 4-strand hamstring autograft for endoscopic recostruction of anterior cruciate ligament:a meta-analysis

Objective] To evaluate knee stability and functional score after double-bundle and single-bundle of 4-strand hamstring autograft for endoscopic anterior cruciate ligament reconstruction.Method] Randomized controlled trials(RCTs) were collected from CENTRAL,PubMed,Embase and CBM database.The Cochrane Collaboration's tool for assessing risk of bias was uaed to assess the quality of the included trials.Data analyses were performed with the Cochrane Collaboration's RevMan 5.0 software.Result]Ten RCTs involvi...
