Genicular Artery Embolization (GAE)
Genicular Artery Embolization (GAE) is an innovative, minimally invasive treatment option for patients suffering from chronic knee pain caused by osteoarthritis. Unlike knee replacement surgery, GAE is performed as an outpatient procedure by a vascular specialist and offers patients meaningful pain relief with little downtime. GAE technical success rates are as high as 99.7%, according to a 2023 meta-analysis by the National Library of Medicine.
At Coastal Vascular & Interventional, we’re committed to helping patients explore less invasive solutions to chronic pain. In this blog, we’ll cover what GAE is, how it works, and what patients can expect from this procedure.

How Does GAE Work?
GAE targets abnormal blood vessels that contribute to knee pain and inflammation. During the procedure:
- A vascular specialist inserts a small catheter into the arteries that supply the knee (called the genicular arteries).
- Using advanced imaging, tiny particles are injected to block abnormal blood flow to the inflamed area.
- By reducing this blood flow, GAE helps minimize pain and inflammation while preserving healthy circulation to the rest of the knee.
Most patients return to daily activities within a few days, making it a highly appealing alternative to surgery.
Benefits of GAE
Patients often consider GAE because it offers:
- Relief from chronic knee pain
- An outpatient, minimally invasive procedure
- Faster recovery compared to knee replacement
- Reduced need for long-term medications or repeated injections
- Preservation of the natural knee joint
- Relief from chronic knee pain
- An outpatient, minimally invasive procedure
- Faster recovery compared to knee replacement
- Reduced need for long-term medications or repeated injections
- Preservation of the natural knee joint

Who is a Candidate for GAE?
GAE may be an excellent option for individuals who:
- Suffer from moderate to severe osteoarthritis of the knee
- Have tried conservative treatments like medications, physical therapy, or injections without success
- Are not ready or eligible for knee replacement surgery
- Want to delay or avoid major surgery.
- Experience daily pain that affects mobility and quality of life
What to Expect After GAE
Because GAE is performed as an outpatient procedure, most patients go home the same day. Recovery is generally quick, with many reporting improved mobility and reduced pain within weeks. Unlike surgery, there’s no hospital stay, and patients can return to normal activities much sooner.
