摘要(Abstract)：

[目的]分析间隙平衡技术在全膝关节置换(total knee arthroplasty,TKA)术中应用的临床效果及注意事项。[方法]回顾分析2004年3月～2006年3月应用间隙平衡(gap balancing,GB)技术的TKA患者45例(49膝),男16例,女29例,手术时年龄52～79岁,平均62.4岁。另取同期采用测量截骨(measured resection,MR)技术的TKA患者70例(76膝)设为对照组。比较分析两组患者的手术情况、影像学、膝关节功能恢复情况。[结果]115例患者均获随访,时间6～8年,平均6.8年。GB组单膝手术时间、胫骨截骨量、股骨截骨量均明显低于MR组,术中股骨假体相对外上髁解剖轴内旋角度GB组大于MR组(P<0.05)。TKA术后两组患者髌骨外倾角度存在显著性差异(P<0.05),GB组明显大于MR组。术后膝关节KSS、VAS评分及并发症发生率两组比较均无显著性差异(P>0.05)。[结论]TKA术中应用GB技术手术时间短,截骨量少,股骨假体相对外上髁解剖轴内旋和髌骨倾斜角度较大,中期随访临床效果和MR技术无明显差异,GB技术应避免内侧软组织过度松解,预防术后屈曲失稳及髌股关节并发症。
