Purpose To determine indications for, operative findings of, and outcomes of revision hip arthroscopy. Methods A systematic review was registered with PROSPERO and performed based on PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Therapeutic clinical outcome studies reporting the indications for, operative findings of, and outcomes of revision hip arthroscopy were eligible for inclusion. All study-, patient-, and hip-specific data were extracted and analyzed. The Modified Coleman Methodology Score was used to assess study quality. Results Five studies were included (348 revision hip arthroscopies; 333 patients; mean age, 31.4 ± 4.2 years; 60% female patients). All 5 studies were either Level III or IV evidence. The surgeon performing revision hip arthroscopy was the same as the primary hip surgeon in only 25% of cases. The mean time between primary and revision hip arthroscopy was 27.8 ± 7.0 months (range, 2 to 193 months). Residual femoroacetabular impingement was the most common indication for and operative finding of revision hip arthroscopy (81% of cases). The most commonly reported revision procedures were femoral osteochondroplasty (24%) and acetabuloplasty (18%). The modified Harris Hip Score was used in all 5 analyzed studies, with significant ( P < .05) improvements observed in all 5 studies (weighted mean, 56.8 ± 3.6 preoperatively v 72.0 ± 8.3 at final follow-up [22.4 ± 9.8 months]; P = .01). Other patient-reported outcomes (Non-Arthritic Hip Score, Hip Outcome Score, 33-item International Hip Outcome Tool, Short Form 12) showed significant improvements but were not used in all 5 analyzed studies. After revision hip arthroscopy, subsequent reported operations were hip arthroplasty in 11 patients and re-revision hip arthroscopy in 8 patients (5% total reoperation rate). Conclusions Revision hip arthroscopy is most commonly performed for residual femoroacetabular impingement, with statistically significant and clinically relevant improvements shown in multiple patient-reported clinical outcome scores at short-term follow-up. The reoperation rate after revision hip arthroscopy is 5% within 2 years, including further arthroscopy or conversion to hip arthroplasty. Level of Evidence Level IV, systematic review of Level III and IV studies.
