Abstract
OBJECTIVE At present, the effect of tranexamic acid (TXA) and epsilon-aminocaproic acid (EACA) on total knee arthroplasty (TKA) remains controversial. Therefore, the aim of this meta-analysis is to compare the differences between the effects of TXA and EACA in TKA. METHODS We used electronic databases, including PubMed, Embase, MEDLINE, Ovid, ScienceDirect, Cochran Library, Google Scholar, clinical trial, and Chinese related databases, for literature search to find any effect of TXA and EACA in TKA. The differences between groups were compared by odds ratio (OR), weighted mean difference (WMD), and 95% confidence interval (CI). A total of four studies, including 3 randomized controlled trials (RCT) and 1 cohort study, were involved in this meta-analysis, involving 1836 participants. Among these participants, 816 belonged to the TXA group and 1020 belonged to the EACA group. RESULTS Meta-analysis indicated no difference in surgery time (WMD = 0.01, 95% CI -0.35 to 0.36), total amount of blood loss (WMD = 0.14, 95% CI -0.09 to 0.37), transfusion rate (OR = 0.74, 95% CI 0.20 to 2.78), transfusion units per patient (SMD = -0.15, 95% CI -0.54 to 0.25), complications (OR = 0.75, 95% CI 0.37 to 1.55), and length of stay (SMD = -0.01, 95% CI -0.11 to 0.08). CONCLUSIONS Our results suggest that the effect of TXA is not superior to EACA in TKA. However, this conclusion still needs to be further confirmed by multicenter and large-sample clinical trials.
