Background
Hip arthroscopy in patients with contralateral total hip arthroplasty (THA) raises concerns about the risk of requiring further surgery. This study compares outcomes between patients undergoing hip arthroscopy with a contralateral THA vs. a native hip.
Methods
A retrospective review of patients who underwent hip arthroscopy from 2008 to 2015. A matched-pair study compared those with contralateral THA and those with native hips.
Key Findings
No significant difference in patient-reported outcomes (PROs) between the two groups. However, the contralateral THA group had a higher conversion rate to THA (67% vs. 15%, P = 0.006).
Conclusions
While PROs were similar, patients with a contralateral THA had a significantly higher rate of conversion to THA, suggesting that hip arthroscopy may not be recommended for this group.
What Does This Mean for Patients
Patients with a contralateral THA may face a higher risk of requiring another THA after hip arthroscopy.
