Overview

Cohort study reveals lower revision and dislocation risk with highly cross-linked polyethylene in total hip arthroplasty, indicating clinical advantages for larger femoral heads.

Key Points

  • To evaluate the long-term risk of all-cause revision, dislocation, and cause-specific revision according to polyethylene liner type in patients undergoing primary total hip arthroplasty.
  • Conducted a population-based cohort study using Danish registry data involving 48,618 patients who underwent primary total hip arthroplasty for osteoarthritis between 2000 and 2016, with follow-up extending up to 10 years.
  • Compared highly cross-linked polyethylene (HXLPE) with non-HXLPE across 28 mm, 32 mm, and 36 mm femoral head sizes using targeted maximum likelihood estimation standardized for age, sex, fixation, and comorbidities.
  • For 36 mm heads, HXLPE showed significant reductions in all-cause revision (standardized risk difference -3.1%, 95% CI -4.5 to -1.6), dislocation (-1.9%, 95% CI -3.1 to -0.6), revision due to dislocation (-1.3%, 95% CI -1.9 to -0.7), and revision due to infection (-0.9%, 95% CI -1.3 to -0.4).
  • For 32 mm heads, HXLPE was associated with lower risk of dislocation (standardized risk difference -1.4%, 95% CI -2.6 to -0.2) and revision due to aseptic loosening (-0.8%, 95% CI -1.1 to -0.5), while 28 mm heads showed no significant differences for any outcome.
