摘　　要：目的:比较基于快速成型及3D打印技术全膝关节置换(TKA)术与传统术式治疗双膝骨性关节炎的效果。方法:选取双膝骨性关节炎患者80例,按照手术方式差异分为观察组(48例)与对照组(32例)。观察组采用基于快速成型及3D打印技术的TKA术治疗。对照组采用传统术式治疗。比较两组围手术期指标(手术时间、失血量、术后48 h引流量)。比较两组手术前后膝关节活动度、膝关节功能(HSS)评分及力线[下肢机械轴夹角(HKA)和冠状位股骨远端机械轴外侧角(mLDFA)]。比较两组并发症发生情况。结果:两组失血量比较差异无统计学意义(P>0.05)。观察组手术时间明显短于对照组,术后48 h引流量明显少于对照组(均P<0.05)。术前,两组膝关节活动度、HSS评分、HKA、冠状位mLDFA比较差异无统计学意义(均P>0.05)。术后6周,观察组膝关节活动度、HSS评分显著高于对照组,HKA与冠状位mLDFA明显小于对照组(均P<0.05)。观察组并发症总发生率明显低于对照组(P<0.05)。结论:相较于传统术式,基于快速成型及3D打印技术TKA术能缩短手术时间,减少术后引流量,改善下肢力线,促进膝关节活动度与功能恢复,且可降低并发症发生风险。Objective:To compare the effects of total knee arthroplasty(TKA)based on rapid prototyping and 3D printing and traditional surgical method in the treatment of bilateral knee osteoarthritis.Methods:A total of 80 patients with bilateral knee osteoarthritis were selected and divided into observation group(48 cases)and control group(32 cases)according to the difference of operation methods.The observation group was treated with TKA based on rapid prototyping and 3D printing technology.The control group was treated with traditional surgery.The perioperative indicators(operation time,blood loss,and drainage volume 48 hours after operation)were compared between the two groups.The range of motion of the knee joint,knee joint function(HSS)score and force line[hip-knee-ankle angle(HKA)and mechanical lateral distal femoral articular angle(mLDFA)]were compared between the two groups before and after surgery.The incidence of complications between the two groups was compared.Results:There was no significant difference in blood loss between two groups(P>0.05).The operation time of the observation group was significantly shorter than that of the control group,and the drainage volume 48 hours after operation was significantly lower than that of the control group(all P<0.05).Before operation,there was no significant difference in range of motion of the knee joint,HSS score,HKA and coronal mLDFA between two groups(all P>0.05).Six weeks after operation,the range of motion of the knee joint and HSS score in the observation group were significantly higher than those in the control group,while HKA and coronal mLDFA were significantly lower than those in the control group(all P<0.05).The total incidence of complications in the observation group was significantly lower than that in the control group(P<0.05).Conclusion:Compared with traditional surgical method,TKA based on rapid prototyping and 3D printing technology can shorten the operation time,reduce postoperative drainage volume,improve lower limb alignment,promote the receovery of k
