Trial Summary

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are using anticoagulants (except for 81mg aspirin) or combination hormonal contraception.

Is tranexamic acid generally safe for humans?

Tranexamic acid has been studied for safety in various conditions, including heavy menstrual bleeding and surgeries like knee and hip replacements. These studies generally support its safety in humans, although specific side effects and risks can vary depending on the condition and dosage.12345

How does the drug Tranexamic Acid differ from other treatments for osteoarthritis?

Tranexamic Acid is unique for osteoarthritis as it is primarily known for its role in reducing bleeding by helping blood to clot, unlike other treatments that focus on pain relief or inflammation control. This novel approach could offer a different mechanism of action compared to traditional therapies like NSAIDs or hyaluronic acid injections.678910

What is the purpose of this trial?

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.

Findings from Research

A high initial dose of 60 mg/kg intravenous tranexamic acid (IV-TXA) significantly reduced peri-operative blood loss and transfusion rates in 132 patients undergoing total knee arthroplasty compared to a lower dose of 20 mg/kg.
Patients receiving the higher dose also experienced lower levels of inflammatory markers and pain in the days following surgery, while maintaining similar coagulation parameters and complication rates as those on the lower dose.

In a study of 60 patients undergoing bilateral total knee arthroplasty, intravenous tranexamic acid (TXA) significantly reduced total blood loss and the need for blood transfusions compared to the control group, indicating its efficacy in managing perioperative blood loss.
The use of TXA did not increase the risk of deep vein thrombosis or other thromboembolic events, suggesting it is a safe option for patients undergoing knee surgery.
