Intramedullary hemostasis further reduces postoperative anemia in patients over 70 years old undergoing total hip arthroplasty.

Purpose: Postoperative anemia has been a threat to total hip arthroplasty patients. We introduced a novel medullary cavity hemostasis (MCH) technique and combined it with tranexamic acid (TXA) to prevent postoperative anemia in elder patients. This trial was conducted to evaluate the effectiveness and safety of this technique.
