Interventions/Control_1	The combined tranexamic acid group received 1000 mg of tranexamic acid administered intravenously just before skin incision of the first hip. After closure of fascia, 1000 mg of tranexamic acid (10 mL of 100 mg/mL tranexamic acid) was administered intra-articularly for each hip. Five hours after the first intravenous administration of tranexamic acid, 1000 mg of tranexamic acid was again given intravenously.
Interventions/Control_2	The intravenous tranexamic acid group received 1000 mg of tranexamic acid administered intravenously just before skin incision of the first hip. After closure of the fascia, 10 mL of normal saline was administered intra-articularly for each hip. Five hours after the first intravenous administration of tranexamic acid, 1000 mg of tranexamic acid was again given intravenously.
