Introduction: Tourniquets are routinely employed during total knee arthroplasty; however, their use remains controversial. Methods: This study investigates the efficacy and safety of this practice. A retrospective analysis of 186 patients was performed to assess benefits and/or risks associated with tourniquet use during knee arthroplasty. Total knee arthroplasty was performed using the Biomet Vanguard® PCL Prosthesis (Biomet, Warsaw, IN, USA). In total, 126 patients who had undergone total knee arthroplasty were included in our final analysis. Results: Patients with tourniquets had significantly less intraoperative blood loss than patients without (P<.001); patients without tourniquets required more blood transfusions (P=551), and had significantly longer surgical times (P=011). However, patients with tourniquets had more postoperative blood loss (P<.001), longer hospital stays (P=013), and more frequent complications (P=571). Blood transfusion requirement was significantly associated with complications (P<.001). Conclusions: Tourniquet use provided no overall benefit.
