Topical Tranexamic Acid Is Effective in Cementless Total Knee Arthroplasty.

Abstract

Surgical techniques used to decrease the amount of blood lost during the procedure range from tourniquets to electrocautery and, more recently, the use of antifibrinolytics. Currently, tranexamic acid is the most commonly used antifibrinolytic in arthroplasty procedures. It was previously thought that intravenous tranexamic acid was more effective than topical tranexamic acid, but had an increased risk of thrombosis and cardiac events; however, this study showed that topical tranexamic acid is as effective in decreasing blood loss and the need for a blood transfusion after hybrid fixation total knee arthroplasty as with cemented total knee arthroplasty.
