CAD Assembly of Total Knee Replacement with Femur and Tibia bones at hyperflexion

The data presented here is a Computer Aided Design (CAD) assembly of Total Knee Replacement (TKR) components with Femur and Tibia bones at hyperflexion (120 degrees of knee). The assembly of Total Knee Replacement components with Femur and Tibia bones at hyperflexion of knee can be visualized; it consists of Femoral component, Bearing component, Tibial component, Femur and Tibia. The CAD models of Total Knee Replacement components were developed using reverse engineering technique. CAD of Femur and Tibia bones were developed using MRI images of an Indian patient. Resection of Femur and Tibia was accomplished with the help of a professional surgeon from Apollo Hospital, Bangalore. The final assembly of Total Knee Replacement components with Femur and Tibia bones was executed in Solidworks [1]. This method is same as published by Kanyal [2]. The assembled model (ASSEMBLY.x_t, or ASSEMBLY.IGS) presented here can be imported to any CAE (Computer Aided Engineering) software like Hypermesh [3], Abaqus [4], Ansys [5] etc. for executing a finite element analysis which might be very crucial for throwing light into knee kinematics and mechanics at hyperflexion of the knee. Therefore, the CAD assembly can prove very useful in a research concerning Total Knee Replacement.

本文提供的数据为膝关节超屈曲（膝关节屈曲120°）状态下，包含股骨、胫骨骨骼的全膝关节置换（Total Knee Replacement, TKR）组件计算机辅助设计（Computer Aided Design, CAD）装配体。该全膝关节置换组件与股骨、胫骨骨骼在膝关节超屈曲状态下的装配体可实现可视化展示，其组成包括股骨假体组件、衬垫组件、胫骨假体组件以及股骨与胫骨骨骼。全膝关节置换组件的CAD模型通过逆向工程技术开发完成；股骨与胫骨骨骼的CAD模型则基于一名印度患者的磁共振成像（Magnetic Resonance Imaging, MRI）图像构建。股骨与胫骨的截骨操作由班加罗尔阿波罗医院（Apollo Hospital, Bangalore）的专业外科医生协助完成。全膝关节置换组件与股骨、胫骨骨骼的最终装配在Solidworks [1] 中完成，该方法与Kanyal等[2]发表的研究一致。本文提供的装配模型（格式为ASSEMBLY.x_t或ASSEMBLY.IGS）可导入至任意计算机辅助工程（Computer Aided Engineering, CAE）软件，如Hypermesh [3]、Abaqus [4]、Ansys [5]等，以开展有限元分析——此类分析对于阐明膝关节超屈曲状态下的运动学与力学特性至关重要。因此，该CAD装配体在全膝关节置换相关研究中具备极高的应用价值。
