Zapping nerves before knee surgery may cut pain — trial puts it to the test

NCT ID NCT07727551

First seen Jul 27, 2026 · Last updated Jul 28, 2026 · Updated 1 time

Summary

This trial tests whether a nerve-blocking procedure called genicular nerve radiofrequency ablation, done two to six weeks before total knee replacement, can reduce postoperative pain and improve function. The study includes adults aged 18 to 60 who are scheduled for knee replacement and have certain risk factors like obesity, diabetes, or chronic pain. Participants are randomly assigned to receive the nerve block or not, and their pain and mobility are tracked after surgery.
