Objectives: The purpose of this study was to evaluate clinical outcomes, pain, and patient satisfaction following revision hip arthroscopy at a high volume referral center with a minimum 2-year follow-up. Methods: During the study period, April 2008 to October 2011, data was prospectively collected on all patients undergoing revision hip arthroscopy. All patients were assessed pre- and post-operatively with 4 patient-reported outcome (PRO) measures: the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score-Activities of Daily Living (HOS-ADL), and Hip Outcome Score-Sport Specific Subscales (HOS-SSS). Pain was estimated on the visual analog scale (VAS). Patient satisfaction was measured on a scale from 0 to 10. Results: Eighty-seven patients underwent revision hip arthroscopy during the study period. Seventy (80.5%) patients were included in our study. In terms of residual FAI morphology, 45.7% of patients had preoperative alpha angles ≥55 degrees and 7.14% of patients had a LCEA ≥40 degrees. The score improvement from preoperative to 2-year follow-up was 57.84 to 73.65 for mHHS, 62.79 to 83.04 for HOSADL, 37.33 to 54.93 for HOS-SSS, 55.65 to 70.79 for NAHS. VAS decreased from 6.72 preoperatively to 4.08 postoperatively. All scores demonstrated statistically significant improvement (P<.001). Overall patient satisfaction was 7.67. Our success rate was 74.58% for primary revision hip arthroscopy and 100% for secondary revision hip arthroscopy. Ten (14.29%) patients underwent total hip arthroplasty during the study period. Our hip survivorship was 85.7%. Five (7.14%) patients underwent secondary revision hip arthroscopy during the study period. We found an overall minor complication rate of 10%. Conclusion: Revision hip arthroscopy for all procedures performed on aggregate has excellent clinical outcomes for all PROs and patient satisfaction scores at short-term follow-up. Patients should be counseled regarding the potential progression of degenerative change leading to arthroplasty, and the potential for revision surgery.
