Summary

This phase 3 trial tests whether taking tranexamic acid (TXA) by mouth for an extended period after total knee replacement can improve recovery. TXA is already used during surgery to reduce bleeding, but its benefits when continued afterward are unclear. The study will compare different durations of extended oral TXA against a placebo in 120 adults undergoing knee replacement, measuring pain, range of motion, and how much patients notice their knee in daily activities.

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) taken orally as extended-release capsules after knee replacement surgery
What this could lead to
If effective, extended oral TXA could become a standard part of recovery after knee replacement, helping patients regain function faster and with less pain.
What could go wrong
This is a single-center trial with 120 participants, and results may not apply to all patients. TXA can increase the risk of blood clots, though the trial excludes high-risk individuals.
