Genicular Artery Embolization for Knee Pain Relief

If you’ve been living with knee pain from osteoarthritis, you already know the routine: physical therapy, medication, maybe an injection or two, and the pain keeps coming back. Genicular artery embolization (GAE) is a minimally invasive treatment that may offer relief for people who have tried conservative options without lasting results and want to explore a path other than knee replacement surgery.

Osteoarthritis affects a large share of adults, with knee OA reported in at least 19% of Americans aged 45 and older (PMC). For many people in this group, GAE has become a way to address knee pain at its source rather than simply managing symptoms.

What Is Genicular Artery Embolization?

Genicular artery embolization, or GAE, is a minimally invasive procedure performed through a tiny pinhole in the skin, not a large incision. A board-certified vascular specialist uses imaging to guide a thin catheter to the blood vessels around the knee.

Over time, arthritis can inflame these blood vessels, which contributes to the chronic pain many people feel with every step. During GAE, your provider reduces blood flow to the inflamed tissue, which can help calm inflammation and ease pain. The procedure does not involve general anesthesia, and most patients go home the same day.

Who Might Benefit From GAE?

GAE isn’t the right fit for everyone, but you may want to talk with a vascular specialist about it if:

• You have ongoing knee pain that hasn’t improved with physical therapy, medication, or injections
• You’re hoping to postpone or avoid total knee replacement
• You’re looking for a treatment option with a shorter recovery time than surgery

Your provider can review your imaging and health history to help determine whether GAE is a reasonable option for your specific case.

What Are the Benefits?

Research on GAE is still developing, but the evidence so far is encouraging for many patients. A 2025 meta-analysis found that GAE can provide meaningful pain relief for a substantial share of people with chronic knee osteoarthritis who have already tried conservative treatments, along with improved function and a low rate of complications (ScienceDirect). In longer-term follow-up data, most patients who responded well at one year continued to see durable relief at two years (JVIR).

Other potential benefits include:

• No large incision, minimal downtime
• No general anesthesia required
• Outpatient procedure, most patients go home the same day
• Pain relief that, for many patients, begins within a few weeks

As with any treatment, individual results vary, and GAE won’t be the right choice for everyone.

What to Expect

A typical path through GAE looks like this:

1. Consultation. You’ll meet with a board-certified vascular specialist to review your knee pain history and imaging.
2. Imaging and mapping. Advanced imaging maps the blood vessels feeding inflammation around your knee.
3. Outpatient procedure. GAE is performed through a tiny pinhole, with no general anesthesia needed, and you go home the same day.
4. Recovery. Downtime is minimal compared to knee replacement surgery, and many patients notice reduced pain within a few weeks.

Risks and Considerations

GAE is not appropriate for every patient, and results vary from person to person. As with any procedure, it’s important to talk with your provider about your full health history, including any bleeding disorders, allergies to contrast dye, or other vascular conditions. Your vascular specialist can walk you through the specific risks and help you weigh them against the potential benefits for your situation.

When to Talk to a Vascular Specialist

It may be worth scheduling a consultation if:

• Physical therapy, medication, or injections haven’t provided lasting knee pain relief
• You want to explore options before committing to knee replacement surgery
• You’re looking for a treatment with a faster recovery than traditional surgery

Taking the Next Step

Chronic knee pain doesn’t have to mean surgery is your only option. If conservative treatments haven’t given you the relief you need, talk with your doctor about whether genicular artery embolization could be a fit, or request a consultation with Vascular & Vein Center to learn more.
