    BackgroundDilute povidone-iodine lavage has been shown to be safe and effective in decreasing acute periprosthetic joint infection (PJI) following total joint arthroplasty (TJA). Vancomycin powder is reported to be effective in preventing infection in spine surgery. We hypothesize that a "vanco-povidone protocol" (VIP) for TJA patients at high risk for infection is safe and will decrease the rate of PJI.MethodsHigh-risk TJA patients (body mass index >40, active smokers, American Society of Anesthesiologists ≥3, immunosuppression/diabetes, methicillin-resistant Staphylococcus aureus colonization, revision surgery) utilizing VIP were compared to a high-risk historical cohort not treated with VIP, at a single institution. VIP consisted of dilute povidone-iodine lavage followed by application of vancomycin powder prior to wound closure. Primary endpoint was PJI within 3 months postoperatively.ResultsThe historical, high-risk control cohort consisted of 3251 patients with a PJI incidence of 1.8%. A total of 1413 subjects received the VIP protocol with a PJI incidence of 1.3%. There was a 27.8% risk reduction when compared to the control group of high-risk subjects not treated with the VIP. There were no medical complications secondary to the use of VIP, no increase in vancomycin-resistant enterococcus or vancomycin-resistant Staph aureus, and no cases of acute renal impairment secondary to application of the local vancomycin.ConclusionsPJI remains a common complication of TJA, especially in high-risk populations. This study indicates that a protocol of dilute povidone-iodine lavage combined with topical vancomycin powder is safe and may reduce PJI incidence in high-risk TJA patients. Due to low, current PJI rates, a multi-institutional randomized controlled trial is necessary to assess interventions that minimize the risk of PJI.Level Of EvidenceRetrospective Observational Cohort.Copyright © 2020.
