Short summary
We compared the re-revision rates in rTHA and rTKA (revison total hip and knee arthroplasty) with and without AB (antibiotic) treatment in patients with UPICs (unexpected positive intraoperative cultures). The re-revision rate between the AB group and the non-AB group was similar. Postoperative AB treatment did not result in a decreased re-revision rate in patients with UPICs in presumed aseptic rTHA and rTKA. Patients with pathogens classified as a likely contaminant can be safely ignored.
