Aim: We conducted a meta-analysis to compare the efficacy and safety of oral and intravenous applications of tranexamic acid (TXA) in total hip arthroplasty (THA).
Materials & methods: Electronic databases, including PubMed, Cochrane CENTRAL, ScienceDirect and Embase, were searched to identify the studies comparing the efficacy and safety of oral and intravenous applications of TXA in THA. Relevant journals and conference proceedings were manually searched. The pooled data were analyzed using RevMan 5.1.
Results: Four randomized control trials and one retrospective study were identified. A meta-analysis showed no significant differences in hemoglobin reduction, total blood loss and transfusion requirements.
Conclusion: Oral applications of TXA are comparable to intravenous applications of TXA in primary unilateral THA for blood conservation and cost-saving measures.
