Could blocking tiny leg arteries relieve knee arthritis pain?

This pilot study tests a procedure called geniculate artery embolization for people with mild to moderate knee osteoarthritis. The treatment blocks abnormal blood vessels in the knee to reduce pain and swelling. Twenty participants will be randomly assigned to either receive the procedure plus standard care (physical therapy and anti-inflammatory drugs) or standard care alone. The goal is to see if the procedure is safe and provides better symptom relief.
