Overview

Systematic review finds equivalent revision and radiolucency rates across three glenoid implant designs in total shoulder arthroplasty, indicating newer modern alternatives perform reliably.

Key Points

  • To compare clinical and radiographic outcomes among all-polyethylene, hybrid, and modern metal-backed glenoid component designs in anatomic total shoulder arthroplasty.
  • Conducted a systematic review adhering to PRISMA guidelines evaluating 37 total studies categorized by glenoid design: all-polyethylene (n = 19), hybrid (n = 5), and modern metal-backed (n = 13).
  • Compared primary endpoints including radiolucency, complication rates, revision rates, range of motion, and patient-reported outcome measures, with meta-regression assessing the effect of follow-up duration.
  • No statistically significant differences were observed across modern metal-backed, all-polyethylene, and hybrid glenoids for radiolucency (P = 0.30) or revision rates (P = 0.28).
  • Range of motion measurements and patient-reported outcome scores showed no statistically significant differences among the three implant designs.
  • Meta-regression demonstrated that longer follow-up times were significantly associated with higher reported revision, complication, and radiolucency rates (P < 0.001 for all).
