目的比较测量截骨与间隙平衡技术在全膝关节置换术（TKA）中应用的中期随访结果。方法回顾性分析2008年5月至2012年8月37例（43膝）采用测量截骨和间隙平衡技术行TKA患者病例资料，测量截骨组19例（22膝），间隙平衡组20例（21膝）。比较分析两组患者疼痛视觉模拟评分（VAS）、膝关节临床症状及功能改善情况。结果成功随访37例（43膝）患者，平均随访时间为4．6年（2～6年）。所有患者术后均能获得良好的临床效果。测量截骨组与间隙平衡组术前和术后末次随访的各项评价指标差异无统计学意义（P＞0．05）。测量截骨组患者主观满意率优良率为90．90％（20／22），间隙平衡组为90．48％（19／21）。结论在TKA中测量截骨与间隙平衡技术中期疗效无明显统计学差异。%Objective To evaluate the mid‐term follow‐up comparison between measured resection and gap balancing technique in total knee arthroplasty (TKA) .Methods Thirty‐seven cases (43 knees) undergoing TKA with measured resection or gap balancing technique from May 2008 to August 2012 were retrospectively analyzed .They were divided into measured resection group (19 cases ,22 knees) and gap balancing group (20 cases ,21 knees) .The data of visual analogue score (VAS) ,clinical and functional outcomes were compared .Results The follow‐up for the 37 cases ranged from 2 to 6 years (average ,4 .6 years) .All cases obtained good clinical results after TKA .The comparison between measured resection group and gap balancing group showed no significant difference (P> 0 .05) .The satisfaction rate was 90 .90%(20/22) in the measured resection group and 90 .48% (19/21) in the gap balancing group .Conclusion There is no statistically significant difference between measured resection and gap balancing technique in TKA on the basis of the mid‐term follow‐up outcome .
