Surgical hip reconstruction reduces the hip joint through soft tissue releases and osteotomies of the femur and/or pelvis. Blood loss and subsequent blood transfusion are normal consequences of hip reconstruction.

the use of antifibrinolytics (AFs) to limit blood loss peri-operatively has been popularized in certain subspecialties. AFs have been studied extensively in adults undergoing various orthopedic procedures including spine and total joint arthroplasty, and have been proven to reduce blood loss and reduce the risk of blood transfusion. Similarly, AFs are used in pediatric patients undergoing cardiac surgery as well as craniofacial operations. Tranexamic acid (TXA) is a synthetic anti-fibrinolytic agent that works by reversibly blocking plasminogen and thereby promoting hemostasis through the prevention of fibrin degradation. Current literature investigating the safety and effectiveness of TXA in children undergoing orthopedic procedures is limited.

We hypothesize that patients treated with TXA will have reduced blood loss and transfusion requirements compared with those who did not receive TXA.
