Summary

The purpose of this study is to determine whether topical or intravenous administration of tranexamic acid during unilateral total knee replacement is more effective at reducing bleeding in the first 24 hours following surgery. Tranexamic acid is a synthetic drug that has been shown to reduce blood drain output and the need for blood transfusions in both its topical and intravenous forms and is commonly used in orthopedic surgery. We hypothesize that IV and topical administration of tranexamic acid will be equally good at reducing the loss of blood and the need for transfusion immediately following total knee replacement.

Interventions

DRUG

Topical Tranexamic Acid

3 vials of tranexamic acid (1g tranexamic acid in 10cc each) must be mixed in the operating room by the team at the start of surgery with 45cc of saline solution (for a total of 3g tranexamic acid in 75mL solution). This solution will be applied to the open joint surfaces with two 60mL syringes (one with 60mL and one with 15m). The solution will be left in contact with the tissues for five minutes. The surgeon will suction away excess solution. The site may be irrigated before or after the tranexamic acid bath as long as the solution is in contact for at least five full minutes. After that, the tourniquet will be released and the rest of the surgery will proceed according to the standard of care.

DRUG

Intravenous Tranexamic Acid

1 vial (1g of IV tranexamic acid in 10mL solution) will be administered prior to inflation of the tourniquet. A second 1g dose of IV tranexamic acid will be given during initiation of the closure after the tourniquet is deflated and during closure.
