What Is Geniculate Artery Embolization and How Does It Work?

There’s a procedure that’s changing the conversation about knee pain — and most people in Naples have never heard of it.

If you’ve been managing chronic knee pain and you’re starting to hear words like “bone on bone” or “it’s time to consider surgery,” there’s something worth knowing first: geniculate artery embolization — GAE — is a clinically proven, outpatient option that’s helping the right patients get back to doing the things they love, without going under the knife.

At the Vascular Center of Naples, Dr. Russell Becker — a fellow-trained vascular surgeon who operates out of a full surgery suite right here in his Naples office — performs GAE for patients who want a real alternative to total knee replacement. He is one of the few physicians in Southwest Florida offering this procedure, and he brings both the training and the outcomes data to back it up.

So what is GAE, exactly?

First described in 2017, GAE is a minimally invasive, image-guided procedure designed to treat chronic knee pain caused by osteoarthritis. Here’s the science in plain language: when osteoarthritis takes hold, your body responds by growing abnormal new blood vessels around the knee joint — a process called angiogenesis. These vessels feed a cycle of ongoing inflammation and nerve sensitization that keeps pain turned on, even when you’re resting.

GAE interrupts that cycle. Using live imaging guidance, Dr. Becker inserts a thin catheter through a small puncture in the skin and navigates it to the specific geniculate arteries supplying those inflamed areas. Microscopic particles are then delivered to selectively block those vessels — reducing blood flow to the abnormal vasculature, decreasing inflammation, and relieving pain.

No incision. No joint replacement. No hospital stay. The whole procedure takes about 1 to 2 hours, and most patients go home the same day.

‍

What does the evidence say?

Clinical studies show cumulative success rates of 85% at two years for patients with mild to moderate osteoarthritis, and 70% for those with more severe cases. Patients report significant reductions in pain, improved mobility, and less reliance on pain medications and injections.

It’s not a cure for arthritis — let’s be clear about that. But for the right patient, it can provide meaningful, durable relief that makes the difference between sitting on the sidelines and getting back on the golf course, the walking trail, or the beach.

‍

Is GAE surgery?

Most patients don’t think of GAE as surgery in the way they’ve been conditioned to fear it. There are no large incisions, no general anesthesia required, and no joint replacement. The procedure is performed in Dr. Becker’s on-site surgery suite — which means you avoid the hospital entirely. You arrive, you’re treated, and you go home.

That’s a fundamentally different experience than knee replacement surgery, which involves a hospital stay, anesthesia, and weeks of rehabilitation. GAE is designed specifically to be a lower-impact option for patients who aren’t ready for — or don’t want — that level of commitment.

‍

Who is a good fit for GAE?

GAE is best suited for patients with mild to moderate osteoarthritis who haven’t found lasting relief from physical therapy, medications, or injections — or who want to delay or avoid knee replacement altogether. It’s also a strong option for patients who face higher surgical risks due to age, obesity, diabetes, or other health conditions. And for patients still dealing with pain after a prior knee replacement, GAE is being used in select cases to address ongoing inflammation.

The key word is “right patient.” At Vascular Center of Naples, Dr. Becker takes candidacy seriously. A thorough evaluation — not a quick consult — is what determines whether GAE is the appropriate next step for you.

Frequently Asked Questions

How long has GAE been around?

GAE was first described in 2017 and has been studied extensively in clinical trials since. It’s not a fringe procedure — it’s a growing standard of care for appropriately selected patients, performed by interventional vascular specialists.

‍

How long does the procedure take?

Typically 1 to 2 hours from start to finish. It’s performed on an outpatient basis in Dr. Becker’s on-site surgical suite, so there’s no hospital admission and no overnight stay.

‍

When will I feel the difference?

Pain relief and improved function are commonly experienced within 2 to 4 weeks as inflammation settles. Most patients resume light activity within 24 to 48 hours of the procedure.

‍

Does insurance cover GAE?

Coverage varies by plan and clinical documentation. The team at Vascular Center of Naples will work with you to verify benefits and walk through what to expect before you schedule.
