Purpose:
This study was designed to evaluate outcomes in women after hip arthroscopy (HA) for femoroacetabular impingement syndrome (FAIS) and compare these results with men.
Methods:
Retrospective study of a prospective database of patients undergoing hip arthroscopy between 2015 and 2018. Inclusion criteria were patients between 18 and 50 years of age, diagnosis of FAIS, complete clinical patient-reported outcomes (PROs), radiographic measurements, and underwent at least a 2-year HA follow-up. For each woman, two men underwent HA were matched in a 1:2 ratio based on age within 5 years, and date of surgery within 6 months. Diagnostic arthroscopy was performed to evaluate labral and chondral status. Radiographic evaluation, a self-administered Hip Outcome Score (HOS) questionnaire, with activity of daily living (ADL) and sports subscale (SSS), and a self-administered short version of the International Hip Outcome Tool (iHOT-12) were assessed at 6 months, 12 months, and then yearly. Clinical relevance was measured with the minimal clinical important difference (MCID), patient acceptable symptom state (PASS), and substantial clinical benefit (SCB) for HOS-ADL, HOS-SSS, and iHOT-12.
Results:
One hundred and eighty-five patients met the inclusion criteria. Fifty-two women were matched with 104 men. Significant differences in terms of demographics, radiographic results, intraoperative findings and arthroscopic procedures were found between women and men. Mean follow-up was 48.4 months in women and 50.2 months in men. Both groups showed significant improvement from preoperative PROs to the latest follow-up. There were no significant differences between groups in preoperative PROs, latest follow-up PROs and PROs improvements. The difference in frequency of patients achieving MCID, PASS, and SCB was only significant greater for iHOT-12 PASS in women compared with men.
Conclusion:
Significant improvements in PROs in women after HA for FAIS at 4-year follow-up were found. Differences between women and men in PROs and rates of achieving MCID, SCB and PASS were only significant for iHOT-12 PASS.
Level Of Evidence:
IV.
