Geniculate artery embolization (GAE) is a minimally-invasive, interventional radiology procedure to reduce pain for patients with knee osteoarthritis.
At University of Maryland Medical Center, our specialists provide GAE as an alternative to knee replacement surgery for some patients.
How Geniculate Artery Embolization Works
Before the procedure, you will have twilight sedation with an additional local anesthetic if needed. Like most interventional radiology procedures, GAE uses a catheter inserted through an incision in the thigh. Using fluoroscopy, a real-time X-ray method, we guide the catheter to the arteries around the knee.
There, we inject tiny particles that block the flow of blood around the lining of the knee. This reduces inflammation and pain.
Although it may take about two weeks for you to feel the full effect, pain relief may last at least one year.
While GAE does not address underlying osteoarthritis conditions, it’s an effective way to manage symptoms.
