Abstract: OBJECTIVE: Tranexamic acid can effectively reduce bleeding during total knee arthroplasty or total hip arthroplasty. However, it may increase the risk of venous thromboembolism. Rivaroxaban can effectively prevent the incidence of venous thromboembolism, but it is associated with bleeding complications. This meta-analysis aims to investigate the safety and efficacy of tranexamic acid combined with rivaroxaban when used in total knee arthroplasty and total hip arthroplasty. 
METHODS: The “tranexamic acid, rivaroxaban, total hip arthroplasty, total hip replacement, total knee arthroplasty, total knee replacement” were used as the search term for English; and “tranexamic acid, rivaroxaban, total knee replacement, total hip replacement” as the search term for Chinese. Clinical trials concerning tranexamic acid and rivaroxaban in total knee arthroplasty and total hip arthroplasty were collected from CNKI, Wanfang Data, PubMed, EMBASE, Cochrane Library and Web of Science databases from inception to May 2020. The quality of included studies was evaluated by RevMan 5.3 software for meta-analysis. The primary outcome measures were total blood loss, hemoglobin reduction, and blood transfusion rate; the secondary outcome measures were the incidence of wound complications and the incidence of deep vein thrombosis.
RESULTS: Nine randomized controlled trials involving 1 795 cases were included. The results of this meta-analysis showed that (1) compared with rivaroxaban group, total blood loss (MD=-216.66, 95%CI:-262.23 to -171.08, P < 0.005), hemoglobin reduction (MD=-0.53, 95%CI:-0.73 to -0.34, P < 0.005), blood transfusion rate (RR=0.28, 95%CI:0.18-0.42, P < 0.05), and the incidence of wound complications (RR=0.52, 95%CI:0.40-0.69, P < 0.05) were significantly lower in the tranexamic acid + rivaroxaban group. (2) There was no significant difference between two groups in the incidence of deep venous thrombosis (RR=-0.88, 95%CI:(0.46-1.67), P=0.69). 
CONCLUSION: The application of tranexamic acid combined with rivaroxaban in the total knee arthroplasty and total hip arthroplasty can effectively reduce total blood loss, hemoglobin reduction, blood transfusion rate, and the incidence of wound complications, but do not increase the incidence of deep venous thrombosis. However, the number and quality of included studies were limited. Therefore, more scientifically designed, large sample, multi-center clinical randomized controlled trials are needed for further verification.
