What this trial studies

This clinical trial evaluates the impact of oral tranexamic acid (TXA) on postoperative pain following total knee arthroplasty (TKA). It is a randomized controlled trial with a 1:1 allocation, where participants receive either TXA or a placebo for three days after surgery. The study will assess various outcomes, including pain levels, range of motion, opioid consumption, and ambulation, over a period of three months. Both patients and surgeons will be blinded to the treatment allocation to ensure unbiased results.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-89 undergoing primary total knee arthroplasty due to knee osteoarthritis.

Not a fit: Patients with a history of stent placement within one year, actively treated cancer, or chronic opioid use may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management and reduced opioid consumption for patients undergoing knee surgery.

How similar studies have performed: Other studies have shown promising results with tranexamic acid in reducing postoperative bleeding, but this specific approach for pain management is less established.

* Currently on a neuroleptic agent \[e.g., gabapentin, pregabalin (Lyrica), duloxetine (Cymbalta) etc.\].
* Non-English speaking and reading patient populations
* Any clinically significant event or condition uncovered during the surgery (e.g., excessive bleeding, acute sepsis) that, in the opinion of the investigator, renders the subject medically unstable or complicates the subject's post-operative course.
