No difference in failure between static, articulating, and prosthetic low-friction spacers for periprosthetic joint infection of total knee arthroplasty.

ABSTRACT: Introduction: Two-stage revision with an antibiotic spacer is the gold-standard treatment of prosthetic joint infection (PJI) for total knee arthroplasty (TKA). Multiple spacer designs exist, including static, articulated, and prosthetic low-friction (PALF) spacers. However, current literature is limited on variant superiority for infection eradication. This study aimed to compare outcomes of two-stage exchange for TKA PJI between patients with static cement, articulated cement, and PALF spacers. Methods: This retrospective study included 93 patients who underwent two-stage revision for PJI following primary TKA and received a static ( n=17 ), articulating ( n=54 ), or low-friction ( n=22 ) spacer. The primary outcome was failure at 2 years, defined as spacer retention, reope
