    BackgroundTranexamic acid (TXA) is an anti-fibrinolytic agent successfully preventing blood loss when using intravenously (IV) in total hip arthroplasty (THA) and total knee arthroplasty (TKA). An oral administration, which is available on blood sparing, has been reported exhibit profound cost-saving benefits. The aim of this meta-analysis is to investigate whether the administration of oral and intravenous tranexamic acid postoperatively has equivalent blood-sparing properties in these patients.MethodsThe online electronic databases were searched for eligible literatures updated on September 2018. Studies assessing the effect between oral TXA and intravenous TXA (IV-TXA) in those undergoing TKA or THA were included. All the data were pooled with the corresponding 95% confidence interval (CI) using RevMan software. Based on the heterogeneity, we performed a systematic analysis to explore the overall results across the included studies.ResultsNine studies met our inclusion criteria. No significant differences were identified with regard to the Hb drop (SMD = - 0.03,95%CI = - 0.18-0.12, P = 0.67), total Hb loss (SMD = 0.10,95%CI = - 0.06-0.26, P = 0.24), total blood loss (SMD = - 0.00,95%CI = - 0.20-0.20, P = 1.00), transfusion rate (OR = 0.77,95%CI = 0.54-1.10, P = 0.14), DVT rate (OR = 0.58,95%CI = 0.19-1.75, P = 0.33), and length of hospital stay (SMD = - 0.05,95%CI = - 0.28-0.17, P = 0.63) between the oral groups and intravenous group.ConclusionThe blood-sparing efficacy of oral TXA is similar to that of the intravenous forms in the setting of THA and TKA. Considering the cost-benefit superiority and ease of administration of oral TXA, further studies and clinical trials are required to further identify the optimal administration for THA and TKA.
