Chronic Ankle Instability Return to Sport

Study Overview
=================
Brief Summary
-----------------
Real-life, observational, monocentric, prospective, longitudinal study, carried out at the European Center for Sports Rehabilitation (CERS), France.

Detailed Description
-----------------
The data will be collected through an electronic Case Report Form completed by the physician, and some auto-questionnaire completed by the patient.

Official Title
-----------------
Return to Sport and Functional Assessment After Surgery for Chronic Lateral Ankle Instability

Conditions
-----------------
Chronic Ankle Instability

Intervention / Treatment
-----------------
* Procedure: Tendon graft
* Procedure: Suture with biological reinforcement


Participation Criteria

Inclusion Criteria: Age ≥ 15 years; Patient treated at the European Sports Rehabilitation Center after a first arthroscopic surgery on the external lateral ligament of the ankle for chronic instability by anatomical reconstruction: With tendon graft; By suture with biological reinforcement; Non-opposition of the patient and his/her parents (if minor) to the collection of his/her personal data. Exclusion Criteria: - Minor patient (age <18 years) not accompanied by one of his/her parents or legal representative during the inclusion visit; History of surgery on the same ankle; Associated complex osteochondral or internal ligament damage, syndesmosis, fracture; Non-anatomical reconstruction; Inability of the patient to understand the study protocol; Vulnerable person whose inclusion is not justified by the purposes of the research: pregnant woman, person undergoing psychiatric care, or adult person subject to legal protection.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Rate of return to main sport at the expected level in both groups | The main objective is to evaluate the rate of patients who returned to sport at the level before the injury, according to their evaluation, 10 months after arthroscopic stabilization according to the surgical technique used (repair by suture or reconstruction by tendon graft). | 10 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Factors associated with the lack of resumption of sport at the level before the injury | Factors associated with the lack of resumption of sport at 10 months at the level before the injury | 10 months | 
| Time taken to resume sport after arthroscopic stabilization | Evaluate the time taken to resume sport after arthroscopic stabilization according to the surgical technique used | 10 months | 
| Functional state of the ankle | Evaluate the functional state of the ankle and the level of activity of the patients during the follow-up according to the surgical technique used | 10 months |
