Genicular Artery Embolization

Comprehensive Treatment for Knee Arthritis at Pain and Vascular Institute

At the Pain and Vascular Institute, we provide comprehensive, minimally invasive solutions for knee arthritis—ranging from advanced image-guided therapies like genicular artery embolization to personalized pain management approaches—helping patients reduce pain, restore mobility, and improve quality of life without major surgery.

What is Genicular Artery Embolization?

Genicular Artery Embolization (GAE) is a minimally invasive procedure that helps relieve knee pain from arthritis. Using a tiny catheter and x-ray imaging, a doctor identifies and blocks the small, abnormal blood vessels in the knee that cause inflammation. This reduces pain, improves mobility, and can delay or even avoid the need for knee replacement surgery—all with no large incisions and a quick recovery.

Why is Genicular Artery Embolization effective?

Knee arthritis is linked to the growth of abnormal blood vessels (“neovascularity”) around the joint. These vessels act as highways, carrying inflammatory chemicals that cause pain, swelling, and further damage to the cartilage. Over time, this creates a harmful cycle where more abnormal vessels form, worsening symptoms and limiting mobility. Genicular Artery Embolization (GAE) breaks this cycle. Using a tiny catheter, we block these abnormal vessels with microscopic particles—shutting down the pathways for inflammation while preserving normal blood flow to the knee. This helps reduce pain, swelling, and progression of arthritis, restoring mobility and improving quality of life.

Frequently Asked Questions regarding

Genicular Artery Embolization:

How do you enter the blood vessels to stop the blood flow?
A tiny incision (less than 1cm) is made in the upper thigh. All our tools enter through this point of access. At the end of the procedure, you will have a small band-aid over the access site.
Will I be awake for this procedure?
We have a board-certified anesthesiologist providing moderate/twilight sedation. You will feel like you are getting a good night sleep and be awake approximately 15 minutes after the procedure. The procedure is painless given the expertise of our anesthesia team.
How long is the procedure?
Average procedure is between 30 minutes to 1 hour.
What can I expect after the procedure?
This is an outpatient, same day surgery. You can return to all normal, daily activities within 24 hours of the procedure with no restrictions.
When can I expect pain relief after the procedure?
Patients typically report significant pain relief within 2-4 weeks of the procedure.
What is the success rate of this procedure?
Clinical research studies show that approximately 70% of patients report significant pain relief for 2-5 years, with many patients being pain free.

In Summary

Genicular Artery Embolization is a proven, minimally invasive treatment option for patients suffering from knee arthritis. It offers long-lasting relief, restores function, and avoids the risks of major surgery—helping patients get back to the activities they love.
