Capsula Closure vs. Non-Capsula Closure: Hip Arthroscopy in Danish Patients With Femoroacetabular Impingement (FAI)

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.
