Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
Total knee joint replacement surgery can lead to significant blood loss, which can affect recovery after surgery. Tranexamic acid (TXA) is a medication which stops the breakdown of blood clots and therefore prevents blood loss. The optimal use of TXA remains a point of debate. Growing interest in the topical application of TXA (directly into the surgical wound) has been suggested as an alternative way of administering TXA, and may demonstrate similar effectiveness as when it is given intravenously. Therefore, this multicentred, randomized controlled trial, aims to investigate the safety and effectiveness of both topical and intravenous administrations of TXA in total knee joint surgery. The investigators predict that both routes of administration will demonstrate similar results when compared to placebo.
