Abstract

The purpose of this study is to investigate the effect of preoperative intravenous (IV) and intraoperative topical administration of tranexamic acid (TXA) in total knee arthroplasty (TKA). A total of 120 patients were and randomly allocated to either topical group, combined group, or control group. The mean total blood loss was lower in the combined and topical groups (705 mL and 579 mL, respectively) in comparison with control group (949 mL, P < 0.001). There was a significant difference in transfusion rate among groups (P = 0.009). The postoperative hemoglobin drop and total drain amount were significantly less in the combined group compared to other groups. In conclusion, combining preoperative IV injection and topical administration of TXA can effectively reduce blood loss and transfusion rate.
