What to Expect Before, During, and After a GAE Procedure

Genicular Artery Embolization (GAE) is a minimally invasive procedure that relieves knee pain, particularly for individuals suffering from osteoarthritis or other degenerative joint conditions. More than 1 in 3 Americans over 60 have knee osteoarthritis, and 40% of them have bothersome symptoms such as pain and limited range of motion.

How do you know if GAE is right for you? Genicular artery embolization is recommended for patients who are 40-80 years of age, have moderate to severe knee pain, were diagnosed with osteoarthritis based on X-ray or other imaging, experience local knee tenderness, and have resistant or failed conservative treatment (medication, physical therapy, joint injections). 

If you are considering GAE or are scheduled for a GAE procedure, understanding what to expect before, during, and after the procedure can help ease your concerns and prepare you for a smoother recovery.

Before the GAE Procedure

Preparation for Genicular Artery Embolization begins with a consultation with an interventional radiologist. During this consultation, your doctor will review your medical history, perform a physical exam, and evaluate imaging studies like X-rays or MRIs to confirm whether GAE is appropriate for you.

You may be advised to avoid eating or drinking for several hours before the procedure. Additionally, your doctor will discuss your current medications and may ask you to pause blood thinners or certain supplements to reduce the risk of bleeding.

On the day of the procedure, wear comfortable clothing and arrange for someone to drive you home. While GAE is an outpatient procedure, you may feel fatigued afterward.

During the GAE Procedure

Genicular Artery Embolization is performed in a specialized interventional radiology suite. The process typically takes 1-2 hours and involves the following steps:

  1. Local Anesthesia: A local anesthetic is applied to numb the skin where the catheter will be inserted.
  2. Catheter Insertion: Using imaging guidance, the radiologist threads a thin catheter through the artery to the blood vessels supplying the inflamed area of your knee.
  3. Embolization: Tiny particles are injected to block the targeted blood vessels, reducing inflammation and pain by decreasing blood flow to the affected area.

You will remain awake during the procedure but should feel minimal discomfort. The radiologist will monitor your vital signs and ensure you’re comfortable throughout.

After the GAE Procedure

The procedure takes about 1-1/2 hours to complete, with an hour of recovery and monitoring afterward. You will be able to return home after that. Most patients will start to achieve significant pain relief a few days after the procedure, and most can reduce their need for pain medication.

You’ll be encouraged to avoid strenuous activities for about a week. However, many patients notice a significant reduction in knee pain within days to weeks of the procedure. Follow-up appointments with your doctor will help monitor your progress and ensure optimal results.

Is GAE Right for You?

If knee pain is limiting your quality of life and other treatments haven’t worked, Genicular Artery Embolization could be a game-changer. Consult with your doctor to determine if this minimally invasive procedure is the right choice for you.
