目的：通过计算机设计来辅助膝关节重建与假体模型制作，为全膝关节置换虚拟手术提供相关的配备。方法把经CT/MR扫描的原始数据输入到Mimics重建三维模型，同时把经LPX激光扫描的关节假体输入到逆向软件Roland 配置的Dr.PICZA来重建假体实物模型，再经分割修补、除噪光顺等后处理，这些成型的3D关节、3D假体将成为供后阶段虚拟TKA(Total Knee Arthroplasty)手术调用的“配件”。结果分别生成清晰的三维骨关节及其网格优化影像，分离出韧带等软组织附件，拟合出可供编辑的CAD (Computer Aided Design)模型。结论成功获得的重建关节与假体模型为下一阶段的模拟手术或有限元分析创造了充裕的条件，进一步完善后可推广于临床。

Objective To process joint rebuilt & prosthesis-model by computer aided design (CAD) so as to prepare relative parts for emulative operation of Total Knee Arthroplasty (TKA).Methods Original data of CT/MR were imported onto Mimics to build 3D model, simultaneously, scanned images of prosthesis joint by Laser instrument LPX were imported onto Reverse Engineering Software called Dr. PICZA installed in Roland in order to rebuild 3D object model, after post-process of segmentation, reparation, denoising & spline-curve, those rebuilt 3D joint and 3D prosthesis will be components available for selection of TKA simulative operation next step.Results Clear image of 3D bone joint were created and meshed in optimization, articular appendage such as ligaments and soft tissues were separated, and editable CAD models were mended. Conclusion These successful rebuilt-joint and prosthesis model will provide good condition for Simulative Operation or Finite Element Analysis next step, and will be popularly practiced in clinic.
