What is Geniculate Artery Embolization?

Geniculate Artery Embolization (GAE) is a minimally invasive procedure designed to reduce knee pain by decreasing blood flow to the inflamed synovium (the lining of the knee joint). By blocking small branches of the geniculate artery, inflammation and pain can be significantly reduced without the need for major surgery.

Benefits of Geniculate Artery Embolization

✔ Minimally Invasive – Performed via a tiny incision, leading to quicker recovery.

✔ Reduced Inflammation – Targets abnormal blood flow to the inflamed knee joint, reducing pain and swelling.

✔ Quick Recovery Time – Most patients resume normal activities within a few days.

✔ Alternative to Surgery – A great option for those looking to avoid or delay knee replacement.

Downsides of Geniculate Artery Embolization

✔ Mid-term Pain Relief – Many patients experience pain reduction for up to two years. However, neovascularization will occur and the pain will eventually return.

Who is a Candidate for GAE?

GAE is ideal for individuals who:

• Suffer from chronic knee pain due to osteoarthritis.

• Have not responded well to conservative treatments like medications or injections.

• Want to delay or avoid knee replacement surgery.

• Are looking for a non-surgical alternative with minimal downtime.

Knee Treatment Research Group Opinion

Geniculate artery embolization offers a good minimally-invasive option. This option is more invasive (as it requires anesthesia and access to the femoral artery) than radiofrequency ablation, but offers more consistent results than radiofrequency ablation. GAE blocks a large number of blood vessels (and their associated nerves) as compared to ablation. However, the blockage of these blood vessels is only temporary. While there are not many long-term research studies it seems that GAE lasts for up to two years. A surgical knee denervation, in contrast, provides permanent pain relief.
