Geniculate Artery Embolization (GAE) is a minimally invasive procedure designed to treat knee pain caused by osteoarthritis (OA) or recurrent bleeding in the knee (hemarthrosis). ​

HOW DOES GAE WORK:

GAE works by blocking small blood vessels in the knee that contribute to inflammation and pain. ​

WHAT IS EMBOLIZATION:

Embolization is a technique where your Interventional Radiologist uses tiny particles to block certain blood vessels that contribute to inflammation and bleeding.

BENEFITS OF GAE:

  • Pain Relief: Studies show significant improvement in pain and knee function. ​
  • Minimally Invasive: No large incisions or long recovery times.
  • Reduces Need for Medications: Many patients reduce or stop using painkillers, including opioids. ​
  • Delays Surgery: GAE may help avoid or postpone knee replacement surgery. ​

THE PROCEDURE:

  • A small catheter is inserted by your Interventional Radiologist into the blood vessels supplying the knee. ​
  • Tiny particles are injected to block the vessels causing inflammation or bleeding.
  • The procedure is done under local anesthesia and typically takes 1–2 hours.

 

RECOVERY:

  • GAE is an outpatient procedure, meaning you can go home the same day.
  • Pain relief is often noticeable within days to weeks. ​
  • Results can last up to 2 years, though some patients may need repeat treatment. ​

 

IDEAL PATIENTS:

  • Have mild to moderate knee Osteoarthritis (OA) who have not found relief with medications, physical therapy, or injections.
  • Want to delay or prevent the need for surgery, such as a total knee replacement.
  • ​Are experiencing hemarthrosis (bleeding inside the knee joint), often caused by trauma, bleeding disorders, or complications after knee surgery. ​
  • Want to stop the bleeding and/or reduce inflammation, preventing further damage to the knee. ​
