Genicular Artery Embolisation (GAE)

Genicular Artery Embolisation (GAE) is a minimally invasive procedure used to treat chronic knee pain, especially from osteoarthritis, when other treatments like medications, physical therapy, or injections haven’t worked.

What is it?

GAE targets the genicular arteries, small blood vessels around the knee joint. In osteoarthritis, these arteries often have increased blood flow and inflammation, which can worsen pain.

Using imaging guidance (usually fluoroscopy or angiography), an interventional radiologist:

Inserts a catheter through a small puncture, usually in the groin or wrist.
Navigates to the genicular arteries.
Injects tiny particles (microspheres) to block abnormal blood flow and reduce inflammation.

Who is it for?

People with moderate to severe knee osteoarthritis
Those who haven’t responded to NSAIDs, injections, or physical therapy
Patients looking to avoid or delay surgery

Benefits:

Reduces chronic knee pain
Minimally invasive and Out patient procedure– no incisions or stitches
Preserves the joint – may delay or avoid the need for knee replacement
Suitable for patients not ideal candidates for surgery
