About

Hip or knee arthroplasties allow a relief of pain and a good functional habilitative at patients suffering from degenerative osteoarthritis of these articulations with medium and long-term good results. The main objective of this study is to compare the efficiency in short and medium-term functional impact parlance of two surgical techniques: computer-assisted surgery and mini-invasive surgery compared to the conventional techniques thanks to an innovative technology of ambulatory analysis of walking.
