Knee Pain & Osteoarthritis

Genicular Artery Embolization or GAE?

Osteoarthritis (OA) is a condition that is caused by repetitive wear and tear of the joints. Damage to the cartilage results in persistent inflammation that causes tiny new blood vessels and nerves to grow within the knee joint. There are new blood vessels and nerves that grow within the lining of the knee joint (Synovium) that cause knee pain associated with osteoarthritis. This pain is often felt by patients when they press on their knee in certain locations or bend the knee joint.


The Interventional Radiologist makes a small needle puncture in to a blood vessel at the top of the leg and guides a microcatheter (similar to thin spaghetti) in to the blood vessels that supply the inflamed part of the knee. The procedure is performed under a ‘twilight sleep’ and should be relatively painless. Microscopic beads are injected in to the areas with abnormal increased flow and the abnormal blood vessels so these are reduced, while normal flow remains to the knee joint. The main arteries to the knee remain open after the procedure.


What are the Advantages of GAE?


No Incisions, or injection in to the knee joint, with less invasive methods


Performed under a twilight sleep or conscious sedation with withou pain


Typically return to work the next day and resume previous activity within a week


Our success rate is over 90% with results typically seen within a few weeks
