摘　　要：背景:膝关节置换后,要求患肢达到负重,伸屈及旋转活动,稳定性好。这就要求假体的几何形状要与人体相匹配并使其植入后与人体运动规律相一致,才能使假体与周围保留的软组织协调运动,这一切都得依赖于精确的膝关节假体设计与制造。目的:利用计算机辅助技术设计个性化人工膝关节。方法:利用三维镭射扫描和计算机辅助设计技术对人体膝关节进行扫描并对所输出的点云数据进行处理,利用工程软件Geomagic和UG进行膝关节三维实体模型重建。结果与结论:得到了非常精确的膝关节三维模型。为中国人工仿生膝关节的数字化制造,虚拟装配,应力分析,运动分析及模拟手术提供了精确的模型基础。BACKGROUND： How to design and manufacture sophisticated artificial knee joint that meets the needs of patients after knee joint replacement rely on the precise design and manufacturing technology, which ensure the prosthesis match the body and make a coordinated movement with maintained soft tissues. OBJECTIVE： To design personalized knee joint utilize of computer-aided design technology. METHODS： The human knee joint was scanned by three-dimensional laser scanning and output of the point cloud data were processed by computer-aided design technology. After that, the three-dimensional solid model of the knee was reconstructed by Geomagic and UG software. RESULTS AND CONCLUSION： A very precise three-dimensional knee model was constructed. It provides an accurate model basis for the digital manufacture of biomimetic artificial knee, virtual assembly, stress analysis, motion analysis, and surgical simulation.
