Cemented metal-on-polyethylene spacers have similar cost profiles with lower complications rates compared to molded all-cement articulating spacers for treatment of knee periprosthetic joint infection

Key Points

• Lower complication rates are reported with cemented metal-on-polyethylene spacers than all-cement articulating spacers.
• Cost profiles are similar, with over 80% of surgical costs incurred during Stage 2 treatment.
• The analysis contrasts two-stage exchange methods in knee periprosthetic joint infections.
• Findings indicate that cemented spacers may be preferable for reducing complications.
