Background
Acetabular retroversion is a structural cause of FAIS traditionally managed with either hip arthroscopy or anteverting PAO. Long-term comparative outcomes of arthroscopic management alone remain limited.
Methods
Prospectively collected cohort of patients undergoing hip arthroscopy for FAIS with acetabular retroversion between 2008–2013 with minimum 10-year follow-up. Patients were propensity-matched 1:1 to nonretroverted FAIS controls based on demographic, radiographic, and surgical variables.
Key Findings
Both cohorts demonstrated significant long-term improvement across all PROs with 96% survivorship in each group. Rates of MCID and PASS were comparable, with the retroversion cohort demonstrating higher SCB achievement for mHHS (P = .04). Low revision and conversion rates were observed across both groups.
Conclusion
In a high-volume surgical setting, advanced arthroscopic management of acetabular retroversion without anteverting PAO yields durable 10-year outcomes comparable to matched controls, with low conversion to THA and revision rates.
