Total knee replacement often requires blood transfusion more so when bilateral surgery is performed. Many strategies are currently being employed to reduce the amount of peri-operative allogenic transfusions. Anti-fibrinolytic compounds such as aminocaproic acid and tranexamic acid have been used systemically in perioperative settings with promising results. This study aimed to evaluate the effectiveness of tranexamic acid in reducing allogenic blood transfusion in total knee replacement surgery. Methodology This was a retrospective cohort study conducted on patients undergoing total knee replacement during the time period November 2005 to November 2008. Study population was 99 patients of which 70 underwent unilateral and 29 bilateral knee replacement. Forty-seven patients with 62 knees group-I had received tranexamic acid by surgeon preference while the remaining fifty-two patients with 66 knees group-II had did not received any tranexamic acid either pre- or post-operatively. Results The mean drop in the post-operative haemoglobin concentration in Group-II for unilateral and bilateral cases was gm dl and gm dl with a mean post-operative drainage of 1828 ml unilateral and 2695 ml bilateral . In comparison the mean drop in the post-op haemoglobin in Group-I was gm dl unilateral and gm dl bilateral with a mean drainage of 826 ml unilateral and 1288 ml bilateral p-value . Interpretation Tranexamic acid is .
