BLOOD LOSS, THROMBOSIS
Patients underwent either conventional THA or robotic arm-assisted THA. The rTHA was operated with a single semiactive surgical robot (YUANHUA-THA) whose surgical procedures were described in the technical manuals provided by the manufacturer. All patients were administered the standard ERAS protocol in our hospital including tranexamic acid (TXA) for blood loss prevention, pain management techniques, thrombosis prevention measures, and functional rehabilitation. Specifically, patients were prescribed a twice-daily dose of 200 mg celecoxib from admission until 14 days after discharge. As part of our TXA protocol, patients received 2 g of intravenous TXA 30 min before the incision, followed by 1 g of intravenous TXA at 3 and 6 h after the surgery. Prior to TXA administration, all patients received 5 mg of dexamethasone intravenously. For thrombosis prevention, low molecular weight heparin (enoxaparin) in 0.2 ml was administered 8 h after the surgery and increased to 0.4 ml per day on subsequent days until discharge. Patients were then prescribed apixaban for two weeks.
