Efficacy and Safety of Tranexamic Acid Combined with Rivaroxaban in Primary Total Knee Arthroplasty: A Meta-Analysis of Randomized Controlled Trials

Abstract

Background Tranexamic acid (TXA) combined with rivaroxaban (RA) has been widely used in total knee replacement (TKA). This meta-analysis explored the clinical effects of TXA combined with RA on reducing bleeding and preventing venous thrombosis in patients with unilateral TKA. Methods Five controlled clinical studies that met the inclusion criteria were collected from PubMed, Embase and Cochrane libraries. Fixed effect model and random effect model were used to compare the TXA + RA group with the RA group in 731 patients. Results Decrease of hemoglobin (Hb), total blood loss, transfusion rate and wound complications of the TXA + RA group is lower than the RA group, the difference was statistically significant (p 0.05). There was no obvious difference of two ways of drug given that intra-articular (IA) and intravenous (IV) effect on Hb decrease, total blood loss, transfusion rate, wound complications, DVT (p > 0.05). Conclusion The application of TXA combined with RA in the TKA can effectively reduce blood loss without increasing the risk of DVT. However, it should be noted that TXA combined with RA after TKA has a potential increased risk of wound complications.
