Abstract

Purpose: To compare the outcomes of hip arthroscopy for femoroacetabular impingement syndrome (FAIS) preoperatively and at minimum 10-year follow-up using patient-reported outcome measures (PROMs).

Methods: A total of 128 patients with FAIS were prospectively included. The patients underwent arthroscopic surgery for FAIS between 2011 and 2013 and had a minimum of 10-year follow-up. The International Hip Outcome Tool short version (iHOT-12) was the primary outcome. Secondary outcomes were the Copenhagen Hip and Groin Outcome Score (HAGOS), the European Quality of Life-5 Dimensions Questionnaire (EQ-5D), the European Quality visual analogue scale (EQ VAS), the Hip Sports Activity Scale (HSAS) for physical activity level, the Visual Analogue Scale (VAS) for overall hip function and a single question regarding overall satisfaction with the surgery. The Wilcoxon signed rank test was used to compare pre- and postoperative PROMs.

Results: There was a significant improvement (p < 0.001) of iHOT-12, HAGOS subscales, EQ-5D, EQ VAS and VAS for overall hip function. A total of 83% of the patients were satisfied with their surgery. The survivorship of hip arthroscopy, defined as nonconversion to total hip arthroplasty (THA), at the end of the follow-up period was 77%.

Conclusion: Patients undergoing arthroscopic treatment for FAIS reported statistically significant and clinically relevant improved outcomes at 10-year follow-up.

Level of evidence: Case series, level IV.
