Genicular Artery Embolization is a minimally invasive procedure that provides immediate and long-term relief to patients with osteoarthritis (OA). The procedure reduces blood flow to the lining of the knee or synovium. The procedure is performed by an interventional radiologist (IR) using X-ray and other imaging such as ultrasound.

Why is it so effective?

  • GAE blocks blood flow to the synovium, reducing inflammation caused by OA
  • It is effective in relieving pain to the point of no longer considering knee replacement surgery
  • It is minimally invasive, so there are no wounds or drains to worry about
  • It can be performed before or after knee replacement

What happens during the procedure?

  • You are given a twilight drug to make you comfortable during the procedure
  • Since it is minimally invasive, there is no need for anesthesia
  • The procedure takes approximately two hours
  • A small catheter is inserted into the artery of the upper thigh
  • With the use of X-rays, the surgeon guides the catheter into the arteries that supply blood to the synovium
  • Particles are released into the arteries through the catheter cutting the blood supply, which in turn reduces inflammation associated with OA and reduces the pain.
