摘　　要：背景:用于外科训练和演练的单髁假体模型因尺寸和特征固定而无法满足个体患者的实际需求。目的:为膝关节单髁置换的数字化研究提供一种三维参数化建模方法。方法:运用三维重建技术建立膝关节炎三维模型,然后通过参数化软件Pro/Engineer5.0设计与骨性模型相匹配的单髁假体,最后模拟膝关节单髁置换并进行三维有限元分析。结果与结论:三维参数化建模法效率高,实现了膝关节单髁假体设计的自动化和高效化,所建模型形态逼真,精确度高。三维参数化建模法为膝关节单髁置换的生物力学研究提供了模型基础和新的实验思路。BACKGROUND： The models of unicompartmental keen athroplasty used for the surgical training and drilling cannot meet the individual requirements due to the size and the fixation.OBJECTIVE： To provide a three-dimensional parametric modeling method for the digital research of unicompartmental keen athroplasty. METHODS： The three-dimensional knee arthritis model was established by three-dimensional reconstruction technique, then, a unicompartmental prosthesis which matched with the osseous model was designed with parametric software Pro/e 5.0. At last, unicompartmental keen athroplasty was simulated and the three-dimensional finite element analysis was performed.RESULTS AND CONCLUSION： Three-dimensional parameteric modeling method was high-performance, and it could make the design of unicompartmental prosthesis automated and high-performanced. The model established based on three-dimensional parametric modeling method had realistic shape and high precision. Three-dimensional parameteric modeling method provides new model-basis and experimental ideas for biomechanical study of unicompartmental keen athroplasty.
