Detailed description
A randomized, double-blind, single-center and controlled study comparing the efficacy and safety of intravenous administration of tranexamic acid to reduce blood loss in simultaneous bilateral total knee arthroplasty. Subjects will be monitored for occurrence of any complications, particularly deep venous thrombosis and thromboembolism during the hospital stay and for 1 months postoperatively
Interventions
