Introduction: For quite a few years, tranexamic acid (TEA) has been used during total knee arthroplasty (TKA) to reduce blood loss. However, no consensus exits regarding its timing and doses. Materials and Methods: We conducted a prospective, randomized double-blinded study of 56 patients in the Indian population undergoing TKA from 2011 to 2012. A dose of 10 mg/kg body weight of TEA (three doses) was given in one group and normal saline was administered in the other. Results: The mean blood loss in the TEA unilateral group was 295 mL ± 218 mL and in the placebo group was 482 mL ± 186 mL (P < 0.005). In the bilateral TEA group, the mean blood loss was 596 mL ± 235 mL and in the placebo group was 1349 mL ± 41 mL (P < 0.005). Conclusion: The number of patients requiring blood transfusion reduced substantially. There was no increase in the risk of deep vein thrombosis (DVT) and pulmonary embolism. TEA reduces intraoperative and postoperative blood loss and thus reduces the need of allogenic blood transfusion.
