Abstract
Introduction: This study was designed to compare the clinical results of additional administration of topical tranexamic acid (TXA) with intravenous TXA (IV-TXA) and to determine its effect in patients undergoing primary total hip arthroplasty (THA) without drainage using propensity score matching analysis.Methods: A total of 248 patients (248 hips) underwent primary THA from March 2016 to June 2018. Patients who received topical TXA and IV-TXA were included in the combined group (46 patients), and patients who received IV-TXA were included in the IV only group (202 patients). After propensity score matching, both groups consisted of 44 patients (88 patients in total). We compared the results of total blood loss (TBL), haemoglobin (Hb) level, Hb drop, and the incidence of deep vein thrombosis (DVT) and pulmonary embolism (PE). Results: In the combined group, the TBL was 280.4 ± 64.2 mL, which was significantly lower than that in the IV only group (335.3 ± 75.3 mL; p < 0.001). From the preoperative period to 1-week postoperatively, Hb levels were not significantly different between the two groups. There was significantly more Hb drop in the IV only Group from immediate postoperative to postoperative day 3 (POD 3). In both groups, no patient presented with postoperative symptomatic DVT or PE. Conclusion: In patients undergoing primary THA without drainage, combined use of IV-TXA and topical TXA can significantly decrease blood loss without influencing postoperative complications.
