Comparison of Efficacy & Safety Between Intravenous and Intraarticular Tranexamic Acid in Reducing Blood Loss after Total Knee Arthroplasty

Abstract

The patients were randomized into 3 groups using online random team generator; (1) Intravenous group, (2) Intraarticular group and (3) Control group. RESULTS: The postoperative blood loss was significantly greater in the control group than in intravenous and intraarticular groups (p = 0.02). Also, the postoperative fall in Hb level and the need for blood transfusion were significantly higher in the control group than in intravenous and intraarticular groups (0.00). However, Intravenous and Intraarticular groups did not differ significantly in terms of the measured variables. There was no significant difference between the preoperative and postoperative platelet counts (p = 0.81), INR (p = 0.21) and serum creatinine (p = 0.39) in all the three study groups. CONCLUSION: Intravenous and intraarticular tranexamic acid were equally effective and safe for reducing blood loss after TKA.
