Abstract
BACKGROUND: Tranexamic acid has been reported to be safer with topical administration than with intravenous administration in total knee arthroplasty. However, the most effective administration route of tranexamic acid in total hip arthroplasty remains controversial. This study compared the effectiveness of topical tranexamic acid administration with that of intravenous tranexamic acid administration in total hip arthroplasty. METHODS: We retrospectively examined the medical records of 886 patients with osteoarthritis of the hip joint, who had undergone unilateral primary total hip arthroplasty. The patients were divided into a control group (n = 302; did not receive tranexamic acid), topical group (n = 265; topically administered 2 g tranexamic acid in 30 mL normal saline via drain tubes placed in the joint before wound closure along with posterior soft tissue repair), and intravenous group (n = 319; intravenously administered 1 g tranexamic acid before skin incision along with posterior soft tissue repair). Data on blood loss, hemoglobin levels, transfusion rates, and occurrence of deep vein thrombosis and pulmonary embolization were collected. RESULTS: The mean operation times were approximately 40 min in all of the groups. The operation time and intra-operative blood loss were significantly lower in the control group than in the topical and intravenous groups. However, the post-operative blood loss, total blood loss, and decrease in the hemoglobin level were significantly higher in the control group than in the topical and intravenous groups. There were no significant differences in terms of blood loss and systemic complications between the tranexamic acid administration methods. CONCLUSIONS: Tranexamic acid reduces both post-operative and total blood loss in total hip arthroplasty. Moreover, a lower amount of tranexamic acid can be used to reduce blood loss in total hip arthroplasty with intravenous tranexamic acid administration than with topical tranexamic acid administration. Therefore, we suggest that tranexamic acid should be intravenously administered pre-operatively and the posterior soft tissue should be repaired to decrease total hip arthroplasty-related complications.
