摘要(Abstract)：

[目的]通过对在计算机导航下的全膝关节置换中计算的截骨厚度和实际的截骨厚度的比较,评价导航下膝关节置换截骨的精确度。[方法]2007年6月～2008年12月,23例24膝初次TKA置换患者,应用无需影像资料的计算机辅助导航仪(O rthoP ilot,Aescu lap,4.0版本)辅助下行后稳定型人工全膝关节(Search(evolution,Aescu-lap)置换手术,将从股骨远端和胫骨近端所截下的骨质用游标卡尺测量与计算机计算的数值比较,进行配对t检验。[结果]23例24膝全部获得随访,平均6.2个月(3～9个月)。HSS评分由术前49.7分,术后增至72分,6个月后为81.2分。股骨远端截骨厚度计算值为(9.30±0.47)mm,测量值为(9.22±0.53)mm,(P=0.21);胫骨平台最高点截骨厚度计算值为(10.24±0.31)mm,测量值为(10.29±0.43)mm,(P=0.61);胫骨平台最低点截骨厚度计算值为(3.46±0.04)mm,测量值为(3.21±0.05)mm,(P=0.18)。[结论]计算机导航在伸直间隙截骨是精确的,术者可以有信心依靠计算机定位的模版来进行截骨。
