Pinhole procedure aims to ease knee arthritis pain without surgery

This study tests a procedure called genicular artery embolization (GAE) for knee osteoarthritis pain. It works by injecting tiny beads into blood vessels that feed inflamed parts of the knee, reducing blood flow and inflammation. About 100 people with moderate to severe knee pain who haven't had success with other treatments will be randomly assigned to get GAE or just observation. The goal is to see if GAE provides significant pain relief at 6 months.
