NCT03158454

Brief Summary

The purpose of this study is to investigate whether patients undergoing surgical treatment (hip arthroscopy) of FAI syndrome will positively benefit from capsular closure, in terms of higher scores in validated patient reported outcome measurements, compared to a Group of patients with FAI syndrome where the capsule is left open at the end of the surgical procedure.
