For many people living with chronic knee pain, the idea of a minimally invasive procedure that reduces pain without surgery sounds almost too good to be true. That’s usually where the skepticism around Genicular Artery Embolization (GAE) begins.
This article will walk you through what GAE actually is, the science behind it, and why it has earned global recognition as a safe and effective treatment.
What Exactly Is GAE?
Genicular Artery Embolization is a minimally invasive procedure performed by interventional radiologists — physicians who use imaging technology to treat disease without traditional surgery.
GAE works by reducing abnormal blood flow to inflamed tissues around the knee, decreasing inflammation and pain caused by osteoarthritis.
Is GAE Safe? Here’s What the Research Says
GAE has been studied for more than a decade, with clinical research published in respected medical journals across the U.S., Japan, and Europe. Key findings include:
- 60–70% average pain reduction reported one year after treatment
- Low complication rates, typically lower than knee replacement or arthroscopic surgery
- No general anesthesia needed
- Most patients walk the same day
These outcomes are consistent across multiple peer-reviewed studies. GAE is not experimental — it’s established and widely practiced in major hospitals worldwide.
Why the Provider Matters
GAE is extremely safe when performed by the right specialty: board-certified interventional radiologists.
These physicians specialize in image-guided, minimally invasive procedures and receive advanced training that orthopedic surgeons or general physicians typically do not.
At KneeFlow, GAE is not one of many services — it’s our specialty. That focus is what increases safety, consistency, and results.
Common Concerns About GAE (And the Truth)
“Is the blood flow blocked forever?”
No. Only the abnormal, inflamed micro-vessels are embolized. Healthy blood flow remains intact.
“Does it damage the knee?”
No. GAE specifically targets soft tissues around the knee, not the cartilage itself.
“Is recovery painful?”
Most patients experience mild soreness for a day or two — often far less than surgical alternatives.
The Bottom Line
GAE is a safe, medically supported, and effective option for knee pain — especially when performed by experienced interventional radiologists. If you’ve been searching for a real alternative to constant injections or joint replacement, GAE offers a path backed by science, not hype
