This multicenter randomized controlled trial evaluated the 1-year infection rates of vancomycin powder and dilute povidone-iodine lavage compared to saline in 2,053 high-risk patients undergoing total hip or knee arthroplasty. The study found no significant differences in periprosthetic joint infection rates, with 1-year PJI rates of 0.5% for vancomycin and 1.6% for TKA, indicating limited influence of these protocols on long-term outcomes.
Key findings
- In the THA cohort, PJI rates were 0.5% for vancomycin and 1.1% for saline (P = 0.62).
- In the TKA cohort, PJI rates were 1.6% for vancomycin and 0.4% for saline (P = 0.05).
- No significant differences in PJI rates were observed from 0 to 3 months or 3 to 12 months.
- Overall, intraoperative antiseptic and antibiotic protocols showed limited influence on longer-term PJI outcomes.
Why it matters
Understanding the effectiveness of infection prevention strategies in high-risk joint arthroplasty patients is crucial for optimizing surgical outcomes and resource allocation. This study suggests that commonly used protocols may not significantly reduce long-term infection rates.
