First Revision Total Hip Arthroplasty for Instability: 10-Year Outcomes and Risk Factors Associated with Re-Revision

This study investigates the 10-year outcomes of first revision total hip arthroplasty (rTHA) performed for instability and identifies risk factors associated with re-revision. The findings reveal that approximately 30% of patients experience further revision within a decade, with dual mobility components showing better survivorship compared to constrained liners. Factors such as younger age, higher body mass index, and abductor deficiency are linked to increased risk of all-cause re-revision.
