Freeze your pain away: new procedure before knee surgery shows promise
NCT ID NCT07425457
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests if freezing the nerves around the knee (cryoneurolysis) one day before total knee replacement surgery can lower pain and help patients move better afterward. About 100 adults with knee arthritis will be randomly assigned to get the freezing procedure plus surgery or surgery alone. Researchers will track their pain and function for 6 months to see if the freezing treatment improves long-term recovery.
