Curtis GL, et al. - The researchers drew a comparison between the infection rates after primary total joint arthroplasty (TJA) using forced-air warmers (FAW) and FAWs with high-efficiency particulate air filters (FAW-HEPA). No link was determined between FAW with a higher risk of overall infection, surgical site infection (SSI) or PJI during TJA in comparison with FAW-HEPA devices.
