Objective
Evaluate 5-year survivorship, patient-reported outcomes, and risk factors for conversion to total hip arthroplasty (THA) after revision hip arthroscopy in obese patients.
Key Findings
- 25% of obese patients underwent THA within 5 years post-revision arthroscopy.
- Over 90% of patients achieved the Minimal Clinically Important Difference (MCID) in multiple outcome measures.
- Older age was a significant predictor of THA conversion, with a nearly 30% increased risk per additional year.
Conclusion
Revision hip arthroscopy in obese patients yields significant functional improvements, but older patients have a notably higher risk of progression to THA.
What Does This Mean for Providers?
- Counsel obese patients on the realistic expectation of functional gains alongside the elevated risk of THA, especially with advancing age.
- Consider patient age carefully during surgical decision-making and follow-up planning.
- Focus on optimizing modifiable risk factors preoperatively when possible to improve long-term joint preservation.
