文题释义:
3D打印个性化截骨导板辅助行全膝关节置换:是术前将患者膝关节的CT扫描数据用计算机软件进行处理,在计算机上进行力线的调整得出最佳的假体横截面的对线,再通过三维成像技术制作截骨模板,此截骨模板具有个性化,截骨角度更确切等优点,术中股骨远端及后髁的截骨量、胫骨截骨的后倾角度与截骨量及术中使用假体的型号都在术前用过计算机测定出来。
3D打印个性化截骨导板辅助行全膝关节置换的优势:与传统的全膝关节置换术相比,其不需要术中使用髓内外导向器反复测量力线,不需要反复测定股骨远端及后髁的截骨量、胫骨截骨的后倾角度与截骨量;也不用反复安放假体试模查看其与关节的匹配程度,尤为重要的是术中无需使用髓内导向器,不需要打开股骨髓腔,这使得术中出血量降低,输血率下降;另外还可以降低由于使用髓内导向器所增加脂肪栓塞的发生率。
 
摘要
背景:传统全膝关节置换术主要利用髓内与髓外对线导向器和术中计算机导航辅助对线技术,但这两种技术都有其缺点。3D打印个性化截骨导板辅助行全膝关节置换具有截骨无需打开髓腔、可以减低出血量、减低脂肪栓塞的发生率、截骨更确切更精准等优势。
目的:探索应用3D打印技术辅助下行全膝人工关节置换与传统全膝人工关节置换术的临床效果及安全性。
方法:纳入2017年1月至2018年1接受初次全膝人工关节置换的10例患者,随机分为2组:3D打印组5例采用3D打印个性化截骨导板辅助下行全膝关节置换手术,传统手术组5例行传统全膝关节置换术。记录两组患者的术前及术后3个月的美国特种外科医院(Hospital for Special Surgery,HSS)膝关节评分、手术时间、出血量、术后X射线影像学评估(包括膝关节正、侧位股骨屈曲角度、胫骨角度)及并发症发生情况。
结果与结论:①与传统手术组比较,3D打印组手术时间显著缩短,出血量明显减少,差异均有显著性意义(P=0.000);②两组的术后3个月膝关节HSS评分及术后X射线影像学评估指标比较差异无显著性意义(P > 0.05);且两组术后3个月膝关节HSS评分与术前比较均显著升高(P=0.000);③两组均无并发症发生;④说明应用3D打印技术辅助下行全膝人工关节置换与传统全膝人工关节置换术均可取得较好的临床效果,且3D打印个性化截骨组件行全膝关节置换的手术时间更短,出血量更少。

Abstract:

BACKGROUND: Traditional total knee arthroplasty mainly depends on the intramedullary/extramedullary alignment guiders and intraoperative computer-assisted navigation technology, but both have disadvantages. Personalized three-dimensional printed osteotomy guider in total knee arthroplasty will not open the medullary cavity, can reduce the blood loss and incidence of fat embolism, and hold exact osteotomy.

OBJECTIVE: To explore the effectiveness and safety of three-dimensional printing technology-assisted total knee arthroplasty versus traditional total knee arthroplasty.
METHODS: Ten patients undergoing primary total knee arthroplasty from January 2017 to January 2018 were enrolled, and randomized into three-dimensional printing and traditional groups (n=5 per group), followed by undergoing total knee arthroplasty using personalized three-dimensional printed osteotomy guider and traditional technology, respectively. The Hospital for Special Surgery scores at baseline and 3 months postoperatively, operation time, blood loss, postoperative anatomical parameters on X-ray films (femoral flexion angle at orthographic and lateral knee, tibia angle), and incidence of complications were recorded in both groups.
RESULTS AND CONCLUSION: (1) The operation time and blood loss in the three-dimensional printing group were significantly less than those in the traditional group (P=0.000). (2) There were no significant differences in the Hospital for Special Surgery scores at 3 months postoperatively and anatomical parameters on X-ray films between two groups (P > 0.05). The Hospital for Special Surgery scores at 3 months postoperatively in both groups were significantly improved compared with the baseline (P=0.000). (3) Complications occurred in neither groups. (4) These results indicate that the three-dimensional printing technology and traditional technology both obtain satisfactory treatment outcomes in total knee arthroplasty. Additionally, personalized three-dimensional printed osteotomy can shorten the operation time and reduce blood loss.
