3D打印技术辅助下行全膝置换术与传统全膝置换术的比较

Comparison of Conventional and 3D Printing-assisted Total Knee Arthroplasty

3D打印技术即三维结构打印技术,是通过3D打印机,以数字模型文件为基础,采用分层加工、迭加成形的方式逐层增加材料来生成3D实体。通过3D打印技术打印个性化截骨组件辅助下行全膝关节置换术(total knee arthroplasty,TKA)比传统TKA有以下优势:采用个性化切模、无需髓内定位器、术中假体安放简便、有效降低术中出血量和心脑血管栓塞并发症的发生率。3D打印技术辅助下行TKA可提前模拟手术并制定最佳手术方案,以达到术中精确定位、减少手术用时、个体化精准治疗的目的,这是医学未来发展的趋势。

Three-dimensional(3D) printing technology refers to processes used to create a three-dimensional object in which layers of material are formed using digital model data from a 3D model under computer control to create an object. Compared with the conventional total knee arthroplasty(TKA),3D printing-assisted TKA possesses the advantages of personalized block printed from a 3D model, no intramedullary nail locator, simple replacement of prosthetic components, reduced intraoperative blood loss and decreased incidence of cardiovascular and cerebrovascular complications. 3D printing-assisted TKA can simulate the operation in advance and develop the best surgical program to achieve accurate positioning during surgery, reduce the operation time, and achieve individualized precision treatment, which is the future of medical development.
