Objective  To evaluate the efficacy and safety of combined use of tranexamic acid (TXA) and dexamethasone (DEX) for anti‐inflammatory and clinical outcomes after total hip arthroplasty (THA).    Methods  A total of 100 patients were included in this randomized, controlled study. Patients in the TXA + DEX group were administered TXA at a dose of 15 mg/kg, which was repeated 3 h after THA, and received 20 mg DEX. In contrast, patients in the TXA group were administered TXA at a dose of 15 mg/kg, which was repeated at 3 h postoperatively. C‐reactive protein (CRP), interleukin‐6 (IL‐6) and pain levels, incidence of postoperative nausea and vomiting (PONV), total blood loss and transfusion rates, postoperative fatigue, range of motion (ROM), length of hospital stay (LOS), analgesic rescue and antiemetic rescue consumption, and complications were compared in both groups.    Results  The CRP and IL‐6 levels were lower in the TXA + DEX group than in the TXA group (all  P  < 0.001) at 24 h, 48 h, and 72 h postoperatively. Patients in the TXA + DEX group had lower pain scores at rest and walking at 24 h postoperatively (all  P  < 0.001). In the TXA + DEX group, the incidence of PONV was lower ( P  = 0.005), postoperative fatigue ( P  < 0.001) was reduced, and analgesia and antiemetic rescue consumption were also reduced. The total blood loss, transfusion rate, LOS and hip ROM were similar in the two groups. There was no thrombosis, infection, or gastrointestinal bleeding in either group.    Conclusion  Compared to TXA alone, the combination of TXA + DEX can reduce postoperative inflammatory response, relieve pain, and reduce PONV and fatigue, without increasing the risk of complications. Therefore, the present study suggested that the combination of TXA + DEX is an effective and safe accelerated rehabilitation strategy for patients receiving primary unilateral THA.
