Genicular or Geniculate Artery Embolization: Is There a Difference?

If you have spent any time researching this procedure, you have probably noticed something odd. Some sources call it genicular artery embolization. Others call it geniculate artery embolization. Our own website address uses one spelling and much of the medical literature uses the other.

So here is the short answer, before anything else.

They are the same procedure

Genicular artery embolization and geniculate artery embolization refer to the identical procedure. Same arteries, same technique, same catheter, same particles, same outcomes. If you found us searching one spelling and you are reading sources that use the other, you have not wandered off into a different treatment. You are in the right place.

The abbreviation is the same either way: GAE.

Where the two spellings come from

Both words trace back to the same Latin root, genu, meaning knee. That is the whole origin of the confusion.

"Genicular" comes from geniculum, a diminutive form meaning "little knee." This is the term used in formal anatomy for the vessels themselves. The arteries surrounding your knee joint are the superior medial genicular artery, the superior lateral genicular artery, the middle genicular artery, the inferior medial and inferior lateral genicular arteries, and the descending genicular artery. Open any anatomy atlas and that is what you will find.

"Geniculate" comes from geniculatus, meaning "bent like a knee." It shows up elsewhere in the body for structures that have a bend in them, which is why you may also encounter the geniculate ganglion, part of the facial nerve, and the lateral geniculate nucleus, part of the visual pathway in the brain. Neither has anything to do with your knee joint.

Because both words share that root, both got used for this procedure as it developed, and both stuck.

Even the medical journals go back and forth

This is not just a patient-facing quirk. It runs through the professional literature.

A widely cited review article in RadioGraphics, one of the primary teaching journals in radiology, is titled "Geniculate Artery Embolization." Inside that same paper, the anatomical diagram labels every single vessel a genicular artery. The title uses one term and the figure uses the other.

You will find the same pattern across clinical trial registrations, journal articles, and practice websites. If it seems inconsistent to you, that is because it genuinely is.

So which one should you use?

Practically speaking, it does not matter. Any qualified specialist will know exactly what you mean either way.

If you want the version most likely to match what you find in current medical literature and billing documentation, "genicular" is the more common term for the arteries themselves and the more frequently used variant in recent publications. But "geniculate artery embolization" remains in wide use, including in peer-reviewed journals and active clinical trials.

You may also see it written as "genicular artery embolisation" with an s, which is simply the British and Australian spelling. Same procedure again.

The confusion that actually matters

Here is the distinction genuinely worth understanding, and it is one that trips patients up far more often than a spelling variation.

Genicular artery embolization is not the same as genicular nerve ablation.

The names are almost identical. The procedures are not.

Both are legitimate, evidence-supported options, and they are not mutually exclusive. There is published work on combining them in difficult cases. But they are different procedures with different mechanisms, different specialists, and different candidacy criteria.

If someone tells you they had "the genicular procedure" for their knee, that sentence is genuinely ambiguous. Ask which one.

Other names you may run into

• GAE. The standard abbreviation, used for either spelling.
• Knee embolization or knee artery embolization. Informal shorthand for the same procedure.
• Transcatheter arterial embolization of the knee. The more technical description you may see in study titles or billing documentation.
• Geniculate artery embolisation. The British and Australian spelling.

All of these describe the procedure Dr. Becker performs at the Vascular Center of Naples.

What the procedure actually is, briefly

Setting terminology aside: in a knee with osteoarthritis, your body grows abnormal new blood vessels into the joint lining. Those vessels bring nerve fibers with them and sustain a cycle of inflammation and heightened pain sensitivity.

GAE uses a catheter, guided by live imaging through a puncture no larger than a pen tip, to deliver microscopic particles that selectively reduce blood flow to those abnormal vessels. The inflammatory cycle is interrupted. No incision into the joint, no general anesthesia, no hospital stay. Most patients go home the same day.

Frequently Asked Questions

Is genicular artery embolization the same as geniculate artery embolization?

Yes. They are two spellings for the identical procedure, both abbreviated GAE. The difference is purely a matter of terminology, not technique or outcome. Both words derive from the Latin root for knee.

‍

Which spelling is correct?

Both are used in the peer-reviewed literature. "Genicular" is the standard term in anatomy for the arteries around the knee and is the more common variant in recent publications, but "geniculate artery embolization" appears in major journals and active clinical trials. Neither is wrong.

‍

Is genicular artery embolization the same as genicular nerve ablation?

No, and this is the more important distinction. Embolization treats the abnormal blood vessels feeding inflammation in the joint. Nerve ablation interrupts the nerves carrying pain signals. Different targets, different techniques, and usually different specialists. Both are legitimate options for the right patient.

‍

What does "genicular" mean?

It comes from the Latin geniculum, meaning "little knee." The genicular arteries are the network of vessels supplying blood to your knee joint. They are the target of GAE.

‍

Why does your website use "geniculate" if "genicular" is more common?

Both terms are correct, and both were in wide use when this practice began offering the procedure. We use them interchangeably so patients can find us regardless of which spelling they searched.

‍

Does the spelling affect my insurance claim?

No. Claims are submitted using standardized procedure codes, not the written name of the procedure. The spelling on a website or in an article has no bearing on how a claim is processed.
