Tranexamic acid (TXA) has been shown to decrease hemoglobin loss and reduce the need for transfusions in primary hip and knee arthroplasty. Recently, authors have proven similar results in revision total knee arthroplasty (TKA). No previous paper has focused on the safety and efficacy of TXA for revision TKA for periprosthetic joint infection (PJI). The purpose of our study was to evaluate the safety and efficacy of topical TXA in revision TKA for PJI. We performed a retrospective review of all patients who underwent two-stage revision total knee arthroplasty for infection at our institution between September 25, 2007 and July 12, 2013. We evaluated hemoglobin loss, need for transfusion, one-year reinfection rate, length of stay (LOS), complications and one-year mortality with and without the use of TXA in all patients who underwent Stage-1 removal of hardware with antibiotic spacer placement and/or revision (Stage-2) for PJI of the knee. All data sets were analyzed using a two-sample t-test.Introduction
