Objective

To report the 5-year survivorship and outcomes for obese patients after revision hip arthroscopic surgery and identify factors that increase the risk of needing a hip replacement.

Key Findings

• 25% of obese patients required conversion to total hip arthroplasty (THA) within 5 years.
• Significant improvement in patient-reported outcomes (PROs), with over 90% achieving MCID in several measures.
• Older age was a significant predictor of needing THA conversion, with each additional year increasing the risk by nearly 30%.

Conclusion

Revision hip arthroscopy in obese patients provides significant functional improvement, though the risk of needing THA increases with age.

What Does This Mean For Patients

If you're obese and require revision hip surgery, expect improvements in your hip function, but be aware that older age may increase the risk of needing a hip replacement later.
