Brief Summary: Our purpose of this study therefore is to conduct a prospective randomized controlled trial to investigate the blood-conservation effect of combined topical application of these two hemostatic agents in different time during surgery and the safety compared with single topical application of TKA in a primary TKA procedure
Detailed Description: Total knee arthroplasty (TKA) is associated with considerable blood loss and increasing needs for allogenic blood transfusion. Tranexamic acid (TXA), an inhibitor of fibrinolysis, was reportedly effective reducing blood loss after standard TKA. Our previous experiences in minimally invasive (MIS) TKA showed that intraoperative infusion of TXA reduced 45% of postoperative blood loss and needs for transfusion from 20% to 4%. There were some reports demonstrating the cost-effectiveness of topical application of TXA in TKA patients. Besides, thrombin-based hemostatic agents, FlosealĀ®(Baxter, Deerfield, Illinois), have been widely used in surgical procedure. Some recent studies demonstrated that topical use of FlosealĀ® in primary TKA can reduce hemoglobin decline and calculated total blood loss after TKA. But other studies showed FlosealĀ® does not reduce blood loss in TKA procedures. We believe the topical use of hemostatic agent in patients with high risk of thromboembolism can avoid its systematic effect and decrease its potential perioperative risk of thromboembolic complications (arterial thrombosis, myocardial infarction and pulmonary embolism). Recently, there were some reports demonstrating the cost-effectiveness of topical application of TXA in TKA patients. The blood saving effect of topical application of TXA in primary TKA was similar with systemic administration. The mean total blood loss of topical route of TXA inTKA patients was 940-1295 ml in different reports which was still high for patients with high thromboembolic risks. However, the efficacy and safety of topical use of TXA in TKA patients with history of thromboembolic disease is still unclear. A more effective regimen for bleeding prophylaxis afer primary TKA is necessary. We believe that combined topical applications of two hemostatic agents of different mechanisms can bring a synergistic effect in blood saving and does not increase the risk of thromboembolic disease after TKA. Our purpose of this study therefore is to conduct a prospective randomized controlled trial to investigate the blood-conservation effect of combined topical application of these two hemostatic agents in different time during surgery and the safety compared with single topical application of TKA in a primary TKA procedure.
