What is Genicular Artery Embolization (GAE): Innovative Treatment for Knee Osteoarthritis and Chronic Knee Pain?

Genicular Artery Embolization (GAE) is a minimally invasive interventional radiology procedure designed to reduce chronic knee pain caused by osteoarthritis. The treatment works by targeting abnormal blood vessels around the knee joint that contribute to inflammation and pain. Using image-guided catheter techniques, tiny embolic particles are delivered to selectively reduce excess blood flow, helping decrease inflammation while preserving healthy joint structures and mobility.

GAE is an effective alternative for patients who have persistent knee pain despite medications, physical therapy, or injections and wish to avoid knee replacement surgery. Performed as an outpatient procedure, GAE offers long-lasting pain relief, improved function, and faster recovery with a strong safety profile.

Conditions Treated

  • Knee osteoarthritis
  • Chronic knee pain not responding to conservative therapy
  • Inflammatory knee pain
  • Knee pain in patients not suitable for surgery
  • Recurrent pain after joint injections

Benefits of Genicular Artery Embolization vs Surgery

Genicular Artery Embolization

  • Minimally invasive, no major incision
  • Outpatient procedure
  • Faster recovery and mobility
  • Lower complication risk
  • Preserves natural knee joint

Knee Surgery

  • Surgical incision required
  • Hospital stay often required
  • Prolonged recovery time
  • Higher surgical risks
  • May involve joint replacement

How the Procedure Works

  • A small catheter is inserted through an artery in the groin or wrist.
  • Imaging identifies inflamed genicular arteries around the knee.
  • Embolic particles are delivered to reduce abnormal blood flow.
  • Inflammation within the knee joint decreases.
  • Pain relief and improved function develop gradually.

What to Expect (Before, During & After)

Risks & Considerations

Genicular artery embolization is considered safe when performed by experienced interventional radiologists. Possible side effects include temporary knee discomfort, bruising, or swelling. Serious complications are rare, and careful imaging guidance helps protect surrounding tissues and blood supply.

Frequently asked question

Yes, many patients experience significant and lasting pain relief. GAE helps reduce inflammation that drives osteoarthritis-related knee pain.

Pain relief can last months to years. Results vary based on disease severity and individual response.

For many patients, yes. GAE avoids major surgery, anesthesia risks, and long rehabilitation associated with knee replacement.

GAE is ideal for patients with moderate to severe knee pain who want a minimally invasive option or are not ready for surgery.
