Overview

Retrospective study reveals revision-free survival of 23 years in ankylosing spondylitis patients, highlighting functional cup positioning efficacy.

Key Points

  • Mean revision-free survival after primary THA was 23 years, indicating favorable long-term outcomes for patients.
  • Overall, the 10-year dislocation-free survival rate was high at 99.1%, reflecting effective surgical techniques.
  • Cemented implants showed greater risk of aseptic loosening compared to noncemented, impacting long-term viability.
  • Differences in survival rates among fixation methods were not statistically significant, suggesting overall procedure reliability.
