Botox vs steroids for knee pain: study pulled before starting
NCT ID NCT03726788
First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 2 times
Summary
This study was designed to see if a Botox injection into the knee joint could relieve arthritis pain better than a steroid injection. Researchers planned to use special MRI scans to measure inflammation. However, the trial was withdrawn before enrolling any participants, so no results are available.
