摘要(Abstract)：

[目的]介绍个性化截骨导板辅助一期全膝关节置换治疗膝关节骨性关节炎合并关节外畸形的技术与初步临床结果。[方法] 2013年3月～2018年6月采用个性化截骨导板辅助全膝关节置换一期手术治疗膝关节骨性关节炎合并关节外畸形患者31例。术前对全下肢行薄层(0.5 mm) CT扫描,重建下肢全长3D影像,设计出截骨平面和截骨厚度,预测假体型号,3-D打印出尼龙材料个体化截骨导板备用。术中在个体化截骨导板引导下进行截骨,安装假体。[结果] 31例患者均顺利完成手术,术中无严重并发症。术后随访12～63个月,平均(37.35±2.61)个月。ROM由术前(83.26±4.13)°增加至末次随访时(97.22±7.81)°。HSS评分从(54.88±6.16)分提高到(85.39±8.93)分。VAS评分由术前(6.86±0.53)分下降至(2.15±0.34)分。影像方面,31例患者冠状位下肢机械轴偏移角度由术前(16.17±5.73)°纠正至(2.93±0.58)°。未见假体松动等不良征象。[结论]在个性化截骨导板辅助下,通过关节内代偿截骨结合软组织平衡技术一期完成全膝关节置换,能够很好恢复下肢机械轴线,获得满意的疗效。
