Construction and Validation of a Score Evaluating the Residual Instability of the Patient After Ankle Ligamentoplasty

The goal of this prospective, open label study is the construction and the evaluation of a composite score evaluating the residual instability in patients who have undergone an ankle's ligamentoplasty (the Ankle Go Test score). The main hypothesis of this study is based on the fact that the composite score "Ankle Go Test" would allow a global validation of all the criteria of scores of 4 tests and 2 questionnaires, which are performed in common pratice, evaluating the instability of the ankle after an ankle ligamentoplasty. Participants will have to complete 2 questionnaires (FAAM, ALR RS) and to undergoe 4 tests (Single Leg Stance Test, Side Hop Test, Start Excursion Balance Test, La figure of 8), at 4, 6 and 12 months post surgery. Researchers will compare the group of participants who undergone ankle's ligamentoplasty with a group of healthy volunteers to assess the discriminant validity of the Ankle Go Test score
