Ten patients (aged 20-60) who have not responded to previous treatment will participate based on informed and written consent. The project uses a prospective cohort design where the patients receive a customized surgical procedure. Data on clinical function, pain and patient satisfaction collected using the AOFAS ankle score, NRS and EQ-5D-5L questionnaire at 6 weeks, 6 months, 1 year and 2 years after the operation.
