title: [Study of model establishment of unicompartmental knee athroplasty based on three-dimensional parametric modeling method].
abstract: The model of knee OA (KOA) was established in our laboratory with three-dimensional (3D) reconstruction technique based on the CT data. We then designed the unicompartmental prosthesis matching KOA model with parametric software Pro/e 5. 0. Finally, the models were used to mimic the operation of knee unicompantment replacement and the model of unicompartmental knee athroplasty (UKA) was analyzed using 3D finite element method. The results indicates that the approach for designing the model by 3D parametric is effective and meets the need of automation and efficacy to design unicompartmental prosthesis. The results proves that the model is vivid and precise, and the 3D parameteric modeling method can provide biomechanical research of unicompantment replacement with model foundation and new experimental method. It can be widely utilized in the clinics and research.
