Design outcomes

Primary

Measure	Time frame
The functional outcome of the ankle will be evaluated using the American Orthopaedic Foot and Ankle Society score (AOFAS). This scoring system is exclusively developed for injury of the ankle and is worldwide the most used and best scoring system for long-term functional outcome. In this questionnaire the aspects of pain, function, stiffness, swelling and the rate of giving way of the ankle will be evaluated in 25 questions. After completion of this questionnaire the obtained score will be between 0 and 100. The lower the obtained score, the worse the ankle function. The scoring system is validated and patient-friendly.	—
