Tranexamic Acid in Total Knee Replacement

A total of 180 patients undergoing TKA for knee osteoarthritis were stratified in three equal groups. All surgeries were performed under spinal anesthesia, without tourniquet and patients should be in agreement with the established inclusion/exclusion criteria. Group A (60 patients) received 1g of IV TXA, Group B (60 patients) received an additional dose of IV TXA and Group C (60 patients) received three doses of IV TXA. The measured outcomes were the Hemoglobin (Hb) decrease, the transfusion rate, the functional, quality of life (QoL) and pain assessment based on their corresponding scoring system.
