What this trial studies

This clinical trial aims to compare the effectiveness of two medications, mirogabalin and pregabalin, in reducing postoperative pain following unilateral primary total knee arthroplasty (TKA). Participants aged 50-85 with osteoarthritis will be randomly assigned to receive either mirogabalin or pregabalin for six weeks post-surgery. The study will evaluate pain levels and functional outcomes to determine which medication provides better pain relief after the procedure.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 50-85 who are undergoing unilateral primary total knee arthroplasty due to osteoarthritis.

Not a fit: Patients with a glomerular filtration rate below 60, severe liver disease, or those who have had previous knee surgery may not benefit from this study.

Why it matters

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

How similar studies have performed: Previous studies have shown promising results in pain management with gabapentinoids, making this approach a potentially valuable addition to postoperative care.
