摘　　要：目的观察应用3D打印技术制作个性化截骨模具辅助完成全膝关节置换术手术时间及术后失血量的变化。方法选取2014年4月—2015年10月在沈阳军区总医院就诊的骨性关节炎12例(16膝)患者为观察组,在3D打印个性化截骨模具辅助下,行全膝关节表面置换术;选取同期骨性关节炎12例(16膝)为对照组,应用传统截骨器械行全膝关节置换术。分别记录两组手术时间、术后48 h引流量及术后总失血量。结果两组术后膝关节疼痛、屈伸活动受限均得到明显改善,下肢力线也获得了满意的效果。两组手术时间比较,差异无统计学意义(P>0.05)。观察组术后48 h引流量及术后总失血量均少于对照组(P<0.05)。结论应用3D打印个性化截骨模具辅助完成全膝关节置换具有创伤小、术后引流量少及术后总出血量少等优点,对全膝关节置换可以起到良好的辅助作用。Objective To observe changes of operative time and postoperative blood loss volume in total knee arthroplasty assisted by individualized 3D printing of osteotomy models.Methods A total of 12 osteoarthritis patients（16knees） with total knee arthroplasty assisted by individualized 3D printing of osteotomy models during April 2014 and October 2015 were selected as observation group,and other 12 patients（16 knees） with traditionally total knee arthroplasty at the same period were selected as control group.Operative time,postoperative 48 h of draining volume and total blood loss volume after surgery were recorded in two groups respectively.Results Symptoms of genual joint pains and limitation of motion in flexor and extensor were significantly improved,and lower extremity of force line was achieved satisfactory effect.There was no significant difference in operative time between the two groups（P〉0.05）.Values of postoperative 48 h of draining volume and total blood loss after surgery in observation group were significantly lower than those in control group（P〈0.05）.Conclusion Total knee arthroplasty assisted by individualized 3D printing of osteotomy models has advantages such as less invasion,draining volume and total blood loss volume with good assisted effect.
