Genicular Artery Embolization (GAE)
GAE is a minimally invasive, non-surgical procedure that reduces inflammation and provides long-term pain relief by targeting the blood flow to the lining of the knee.
Genicular Artery Embolization (GAE): A Breakthrough for Knee Pain
If you suffer from chronic knee pain due to osteoarthritis and haven't found relief through injections or physical therapy—but aren't ready for a total knee replacement—Genicular Artery Embolization (GAE) may be the solution.
Understanding the Condition
Osteoarthritis causes 'neovascularity'—the growth of new, abnormal blood vessels in the synovium (the lining of the knee joint). These vessels are accompanied by new sensory nerves that transmit pain signals to your brain.
How the Procedure Works
Access
An interventional radiologist makes a tiny incision (the size of a grain of rice) in the upper thigh to access the arterial system.
Navigation
Using real-time X-ray guidance, a thin catheter is threaded to the genicular arteries supplying the knee.
Embolization
Tiny particles are injected into these specific arteries to slow the blood flow.
Relief
By reducing the blood flow, the procedure 'starves' the inflammation and calms the hyper-sensitive nerves, significantly reducing pain.
Key Benefits & Advantages
No Surgery: No large incisions, no stitches, and no general anesthesia.
Quick Recovery: Most patients return to light activity within 24–48 hours.
Preservation: It does not prevent you from having a knee replacement in the future if it eventually becomes necessary.
High Success Rate: Clinical studies show that a majority of patients experience significant pain reduction and improved mobility for 12 months or longer.
Recovery & Aftercare
The entire process typically takes about 45 to 90 minutes. Performed under 'moderate sedation' (twilight sleep), you remain comfortable and go home the same day with nothing more than a small bandage on your hip. Pro Tip: While many patients feel relief within the first week, the 'peak' benefits are usually felt around 2 to 4 weeks as the internal inflammation fully subsides.
Frequently Asked Questions
Q. Does it hurt?
Most patients feel a slight pressure during the procedure but no significant pain. Some minor 'aching' in the knee is common for a few days after as the body adjusts.
Q. Will insurance cover GAE?
Coverage varies by provider. Since GAE is a newer procedure, our office can help you navigate the prior authorization process to determine your specific benefits.
Q. How long do the results last?
Current clinical data suggests that many patients enjoy significant relief for 1 to 2 years, with some studies showing even longer-lasting results.
