Introduction: Among the various strategies for in routine total knee replacement (TKR), tranexamic acid (TA) has always been a safer and affordable method. Surgeons have used it in intravenous, intraarticular or in a combined manner to reduce blood loss because it is easily available and has an easy dosing regimen. We aim to find out its efficacy and associated complication when used intravenously. Materials and Methods: This study was done in our institute among 27 cases who was operated for primary TKR. They were distributed into two groups based on the use of TA. Hemodynamic parameters such as blood loss, reduction in hemoglobin (Hb), and blood transfusion were assessed. Student's t-test and ANOVA were utilized for tests of significance. Results: Out of 27 patients, 17 (62.9%) were female and in the age group of 51–60 years. Most 22 (81.5%) had osteoarthritis. The difference in blood loss across various pathologies and comorbidities was statistically insignificant. Average blood loss was 266.2 ml ± 64 ml (Range = 150–406 ml) per TKR in the 1st group. In 2nd, it was 667.5 ± 111.5 ml (Range = 414–860 ml) (P < 0.001). Mean Hb loss was 0.78 ± 0.275 g/dl (Range = 0.1–1.2 g/dl) in Group A. It was statistically significant comparing to Group B where it was 1.86 ± 0.55 g/dl (Range = 1.5–3.7 g/dl). Tourniquet used though decreased blood loss, it was not statistically significant. Conclusion: TA used in intravenously is very effective in decreasing the loss of blood and transfusion requirements in patients of primary TKR.
