3D打印个性化导航截骨导板在膝关节置换中的应用研究进展

Research progress in application of 3D printing patient-specific navigation osteotomy instrument on knee arthroplasty

由于膝关节置换具有良好的临床效果,其在膝关节骨性关节炎治疗中的应用逐年增加。膝关节置换种类多样,精准截骨是决定膝关节置换手术疗效的关键因素之一。应用计算机辅助设计与3D打印技术制造的个性化导航截骨导板种类较多,作用各异,可以辅助术者寻找膝关节的重要解剖点;可以起到固定钉的作用,对截骨导板进行固定;充当截骨导板完成一部分或者多部分的截骨,可操作简单,创伤小,截骨准确,并可预测膝关节假体大小,学习曲线短,实现了膝关节置换的个性化精准治疗。现就3D打印个性化导航截骨导板在膝关节置换中的应用作一综述。

Due to the good clinical effect of knee arthroplasty,its application in the treatment of knee osteoarthritis is increasing year by year.There are various types of knee arthroplasty and accurate osteotomy is one of the key factors to determine the curative effect of knee arthroplasty.There are many kinds of patient-specific navigation osteotomy instruments made by computer aided design and 3D printing technology,and their functions are different.It can assist the surgeon to find the important anatomical points of knee joint;and can play the role of fixing nails,fixation of osteotomy instrument plate;as the osteotomy instrument to complete part or more osteotomy,it has the advantages of simple operation,small trauma,accurate osteotomy,and can predict the size of knee prosthesis,short learning curve,and realize the personalized and accurate treatment of knee arthroplasty.This article reviews the application of 3D printing patient specific navigation osteotomy instrument in knee arthroplasty.
