Abstract Many causes can be at the origin of hip osteoarthritis, but the exact pathogenesis for idiopathic osteoarthritis has not yet been clearly delineated. Indeed, changes in the movement and alignment of the hip could be other potential causes of early osteoarthritis. In particular, athletes seem to present a higher risk of developing such disease due to repetitive and extreme movements performed during their daily activities. In this thesis, a clinical study with professional ballet dancers is being conducted. The goal of this study is to verify if repetitive extreme movements can be a factor of hip joint degeneration through joint subluxation and excessive cartilage deformations. To achieve these goals, we developed a motion protocol using optical motion capture system to estimate the kinematics of patient-specific hip joint 3D models. We also developed an effective and robust correction method to minimize soft tissue artifacts, a critical issue in human motion analysis.
