First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests whether injecting tiny beads into arteries around the knee can reduce pain in people with moderate to severe knee osteoarthritis. The beads block blood flow to the painful area. Nine adults aged 40 to 80 who have not gotten relief from standard treatments are taking part. Researchers will measure pain changes and watch for side effects.

What this could lead to

If it works, this could offer a new way to reduce knee pain without surgery or long-term medication.
