Title of the PhD Project: Validation of prosthetic joint implants through the coupling of in silico methods and experimental data collection
Supervisor(s): Prof.ssa Francesca Di Puccio, Prof.ssa Lorenza Mattei
In collaboration with: “Sport&Anatomy “ Biomechanics Lab
Abstract of the PhD project: To address the limitations of traditional clinical trials for orthopedic implants, this PhD research methodology focuses on three main approaches: motion analysis, musculoskeletal modeling, and Finite Element Method (FEM) analysis. Motion analysis is performed using infrared stereophotogrammetric cameras to capture marker movements on subjects performing specific motor tasks, while force platforms measure ground reaction forces. The data obtained are used to create a lower body or whole body musculoskeletal model using OpenSim software, which is adapted to each subject based on the marker data. This approach enables inverse kinematics and dynamics analyses to estimate model muscle forces and joint moments. In addition, from CT scans and CAD files of the implants, FEM models of the pelvis and joint implants are generated to set up long time wear simulations within the Ansys solver. This integrated approach aims to enhance the predictive accuracy of implant performance and reduce the costs and time associated with conventional clinical testing.
