The purpose of our study was to evaluate the efficacy of TXA in primary THA to support the combined clinical practice guidelines of the American Association of Hip and Knee Surgeons, American Academy of Orthopaedic Surgeons, Hip Society, Knee Society, and American Society of Regional Anesthesia and Pain Medicine on the use of TXA in primary total joint arthroplasty. Methods: A search was performed using Ovid-MEDLINE, Embase, Cochrane Reviews, Scopus, and Web of Science databases to identify all publications before July 2017 on TXA in primary THA. We completed qualitative and quantitative homogeneity testing of all included studies. Direct and indirect comparisons were analyzed using a network meta-analysis followed by consistency testing of the results. Results: Two thousand one hundred thirteen publications underwent critical appraisal with 34 publications identified as representing the best available evidence for inclusion in the analysis. Topical, intravenous, and oral TXA formulations provided reduced blood loss and risk of transfusion compared to placebo, but no formulation was clearly superior. Use of repeat doses, higher doses, or variation in timing of administration did not significantly reduce blood loss or risk of transfusion. Conclusions: Strong evidence supports the use of TXA to reduce blood loss and risk of transfusion after primary THA. No specific routes of administration, dosage, dosing regimen, or time of administration provides clearly superior blood-sparing properties.
