Patient-Reported Outcomes Improve at 2-Year Minimum Follow-up After Hip Arthroscopy for Femoroacetabular Impingement Syndrome: A Systematic Review

Published:November 04, 2022DOI:



      To provide an updated review of recent literature on postoperative outcomes following hip arthroscopy for FAIS, focusing on larger population studies with a minimum 2-year follow-up published within the last five years.


      A literature search of the Pubmed, Ovid Medline, Web of Science, and Cochrane databases was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Articles were screened for clinical studies published from 2017 to 2022 with greater than 100 patients and minimum 2-year follow-up. Exclusion criteria included failure to report postoperative patient-reported outcomes (PROs), no preoperative radiographic measurements, and surgery for pathology other than FAIS. Data collection included study characteristics, patient demographics, radiographic findings, intraoperative findings, procedures performed, postoperative PROs, and subsequent surgeries.


      Nine studies met inclusion criteria. Mean or median patient ages ranged from 32.3 to 41 years, with four studies reporting on greater than 50% females. Mean preoperative lateral center edge angles and alpha angles ranged from 30.2° to 37° and from 56.2° to 71°, respectively. Labral repairs (range, 69.7% to 100%) were performed more commonly than debridements (range, 0% to 26.3%). All studies demonstrated improved PROs at most recent follow-up. Seven studies reported mean or median modified Harris Hip Scores (mHHS), with preoperative and postoperative values that ranged from 53.1 to 80 and from 67.4 to 100, respectively. Revision hip arthroscopies and conversions to hip arthroplasty ranged from 0.8% to 11.6% and from 0% to 34%, respectively.


      All included studies found improvements in PROs after hip arthroscopy for FAIS at a minimum of 2-year follow-up. Conversion to THA is most common in older patients at minimum 10-year follow-up.
