Inclusion criteria
Inclusion criteria: - Male or female patient diagnosed with chronic lateral ankle instability (multiple ankle inversion trauma within 12 months and symptoms present >1 year). Lateral ankle instability is present if the patient complains of giving way of the ankle and has positive signs of ankle instability during physical exam (talar tilt score of >15 degrees compared to contralateral ankle or anterior drawer test score of >10mm compared to the contralateral ankle. - Conservative therapy has failed. - Normal foot and ankle anatomy as determined by orthopedic surgeon. - Patients in whom their ankle symptoms interfere with their physical activities. - Patients between the age of 18 and 60 years. - Patients with isolated anterior talofibular ligament which is indicated for repair using the Brostrom-Gould technique. - BMI

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The difference in FAOS score three months after surgery between the Intervention Group and the Control Group is the main study endpoint. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary endpoints are the incidence of recurrent ankle inversion trauma within one year after surgery and differences in subjective and objective ankle stability, motor control, pain, ankle function and satisfaction with the treatment between the IG and the CG. This will be determined by means of questionnaires, physical examination and clinimetric testing. | — |
