Genicular Artery Embolization (GAE): Relief From Knee Pain Without Surgery

Patient Flow

At Advanced Vascular Centers, GAE is performed by expert interventionalists following the original Okuno method, below you can find information on the individual steps we take for each patient. 

1. Pre-procedural consultation

As a patient, you will meet with the doctor beforehand and we review your symptoms, exam findings, prior medical record, and prior imaging (X-ray, MRI, or CT) to confirm your diagnosis. We discuss your case in depth and make sure you have a complete understanding of the procedure.

2. Procedure day

• Check in – One to two hours beforehand to prepare and to review your medical history.
• Numbing medication – Local numbing medication is given at the access site (usually the groin or ankle).  A mild relaxing medication can be given to make you comfortable as well. A nurse will be monitoring your blood pressure as a precaution while our doctor is performing the procedure. 
• Access – A tiny IV needle accesses the blood vessel and a catheter is inserted and guided into the genicular arteries supplying the knee joint (see video).
• Treatment – Once the catheter is in the correct position, medication is injected to block the abnormal vessels. The normal blood vessels supplying the knee joint remain open.
• Completion – The catheter is removed, and a small bandage is applied—no stitches.

3. Recovery

• Rest for approximately 30 minutes after the procedure.
• You go home about 1 hour after the procedure.
• Resume light activity the next day.
• Full activity will resume in about 1 week.
• Pain relief typically begins within 2–4 weeks and can be sustained for 2+ years.

4. Follow-up

• 1 month after the procedure we see you in our clinic to check how you are feeling after the treatment.
  • If you are progressing as expected, no further follow up is needed. 
• We love hearing and sharing in our patients’ success so we encourage all our patients to follow up as needed!

What Results Can I Expect?

GAE provides meaningful relief for most people with knee pain:

• Reduced knee pain with walking, climbing stairs, hiking, and other activities
• Decreased stiffness and swelling
• Improved mobility and function
• Lower dependence on pain medications or injections
• Delays the need for total knee replacement

Studies show that the majority of patients report long lasting pain reduction after GAE, especially in early- to mid-stage arthritis.

Is Genicular Artery Embolization Right for Me?

You may be a good candidate if you:

• Have knee osteoarthritis that causes pain or limits mobility
• Tried injections, therapy, or medications without relief
• Are not ready for or cannot undergo total knee replacement
• Want a non-surgical solution with virtually zero recovery time

Our team will evaluate your condition and imaging to see if GAE is appropriate for you.
