Is this trial a fit for you?
✓Likely a good fit
Active individuals with chronic lateral ankle instability who have not responded to conservative treatment and are planned for augmentation repair.
✕Probably not a fit
Patients not undergoing surgery or those with other lower-limb conditions may not experience measurable mobility improvements from this study.

What this trial studies
This prospective interventional study analyzes changes in lower-limb biomechanics after augmentation repair of lateral ankle ligaments in patients with chronic instability. Participants undergo biomechanical motion analysis to quantify movement patterns and stability during typical activities. The goal is to identify objective measures of functional recovery to guide rehabilitation and return-to-sport decisions. The study compares biomechanical data collected postoperatively to baseline expectations, helping clinicians understand recovery trajectories. It is conducted at Clinique du Sport in Mérignac with patients who had persistent instability despite conservative treatment.
Why it matters
Potential benefit: If successful, the study could provide objective benchmarks to tailor rehabilitation and improve return-to-sport timing after ankle ligament repair.
How similar studies have gone: Previous work in motion analysis has shown promise in understanding ankle biomechanics after surgery, though this exact augmentation approach is less established.

Inclusion Criteria: * Standard indications for lateral ankle ligament repair surgery for chronic lateral ankle instability refractory to conservative treatment. * Participation in physical activity and/or sports at least once weekly before the onset of symptoms leading to the surgical indication. Exclusion Criteria: * Concomitant surgical procedures likely to alter postoperative recovery. * History of major lower-limb fractures. * Associated injuries involving the lower limbs or lumbar spine. * Any other surgery performed within 6 months prior to the index procedure.
