Overview

Registry study analyzes revision rates of shoulder arthroplasties in young patients, suggesting safer options.

Key Points

  • This study aims to evaluate the cumulative revision rates of shoulder arthroplasties in patients under 55 years with primary osteoarthritis.
  • Comparative observational registry study of shoulder arthroplasties conducted for primary osteoarthritis from 2005 to 2022.
  • Cumulative percent revision rates calculated using Kaplan-Meier estimates and Cox proportional hazard models adjusted for gender.
  • Data from 2111 primary shoulder arthroplasties analyzed for causes of revisions and outcomes.
  • 6-year cumulative percent revision rates: 12.8% for humeral resurfacing, 14.1% for hemiarthroplasty, 12.4% for stemmed aTSA, 7.0% for stemless aTSA, and 6.5% for rTSA.
  • Stemmed aTSA had a higher revision rate than rTSA (HR=2.04, 95% CI 1.16-3.57, P=0.012).
  • No significant difference between revision rates for stemless aTSA and rTSA (HR=1.05, 95% CI 0.51-2.19, P=0.889).
