Extended Oral Tranexamic Acid After Total Knee Arthroplasty

United States120 participantsStarted 2024-09-17

Plain-language summary

The utilization of intraoperative tranexamic acid (TXA), whether administered intravenously or orally, has become a standard practice in total joint arthroplasty (TJA). Multiple studies have demonstrated the positive impact that TXA application has on clinical outcomes, including decreased blood loss and transfusion rates, decreased early swelling and ecchymosis, improved early recovery, and potentially superior long-term outcomes. Its ability to mitigate risk of blood loss made ambulatory total knee arthroplasty (TKA) safer for patients. The safety of intraoperative TXA use has also been documented. Sabbag et al. showed that TXA does not increase the risk of venous thromboembolism (VTE), even in those patients who are deemed high-risk. Multiple routes of TXA administration have been studied with each route demonstrating effectiveness in reducing blood loss. Findings showed that oral TXA is noninferior to intravenous TXA, though the median time to reach a target concentration is longer via the oral route and bioavailability is lower. With the benefits of intraoperative TXA clearly documented in literature, multiple centers investigated the utilization of extended TXA postoperatively in hopes of enhancing patient safety and reducing length of stay and healthcare cost. However, these studies reported conflicting outcomes and mostly focused on estimated blood loss, instead of patient reported outcomes. The purpose of this study is to assess the effectiveness and safety of a varying extended oral TXA regimen during the postoperative period. Further, the investigators aim to determine the optimal duration of the TXA regimen to maximize its impact. The investigators hypothesize that an extended oral TXA regimen is safe and effective in improving clinical outcomes in TKA patients.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
