@@@@BACKGROUND: The models of unicompartmental keen athroplasty used for the surgical training and dril ing 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.
