Primary Outcome Measures

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

Secondary Outcome Measures

Name	Time	Method
<p>- VAS-pain<br /><br>- Olerud & Molander ankle score (short term)<br /><br>- AOFAS foot and ankle score (long term)<br /><br>- Range of motion<br /><br>- Osteoarthritis (AO-scale)<br /><br>- Complications<br /><br>- Secondary interventions/reoperations<br /><br>- Tibiotalar gap or step-off (CT scan postoperatively)</p><br>
