Could a three-day pill course after joint replacement speed up recovery?
NCT ID NCT07685743
First seen Jul 06, 2026 · Last updated Jul 09, 2026 · Updated 3 times
Summary
This trial tests whether taking the anti-bleeding medication tranexamic acid (TXA) for three days after hip or knee replacement surgery helps people recover faster and with less pain. Adults with osteoarthritis who are having a first-time joint replacement receive either TXA or a placebo pill on days 1, 2, and 3 after surgery, in addition to standard TXA given before the incision. Researchers measure joint function, pain, and range of motion at 2, 6, and 12 weeks after surgery to see if the extended TXA regimen improves outcomes without raising complication risks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tranexamic acid (TXA)
- What this could lead to
- If it works, this could lead to a simple, low-cost way to improve recovery and reduce blood loss after joint replacement surgery.
- What could go wrong
- This is a small, early-phase trial, so results may not apply to all patients. TXA can rarely cause blood clots or allergic reactions.
