The study was set up as a clinical trial including patients over an observation period of one year and a control group of subjects. Clinical evaluations will be made at baseline, 3 months, 6 months and 1 year after surgery by two independent observers. Miniature sensors each containing three 3D gyroscopes and three 3D accelerometers will allow computing new kinematic scores. They will be compared to the regular SST, DASH, ASES and Constant scores.
