INTRODUCTION: Forced-air warming devices have been reported to present a potential risk for surgical site infections (SSIs) and periprosthetic joint infections. Due to a lack of consensus, we reviewed the infection risk of forced-air warming devices. MATERIALS AND METHODS: A systematic literature review was performed, evaluating overall infection risk and bacterial load. A total of eight studies reporting outcomes from 1,965 subjects were included. RESULTS AND CONCLUSIONS: There is no current evidence in the orthopaedic literature that forced-air warming devices translate to increased SSIs. Accordingly, these devices should continue to be used for the maintenance of intraoperative normothermia.
