Genicular Artery Embolization
Make Appointments & Get Care
What is Genicular Artery Embolization (GAE)?
Genicular artery embolization (GAE) is a minimally invasive procedure that can help relieve chronic knee pain caused by osteoarthritis.
During the procedure, an interventional radiologist uses advanced imaging to block tiny blood vessels that contribute to inflammation inside the knee. Reducing this abnormal blood flow can decrease pain and improve function.
Who is Eligible for Genicular Arter Embolization?
You may be eligible for GAE if knee replacement surgery isn’t right for you, and you have knee pain from osteoarthritis that is not improving despite:
- Medications
- Physical therapy
- Injections
Our experts will complete a full evaluation to determine whether GAE is the best treatment option for you.
Our Approach
Our Interventional Radiology specialists work closely with experts in orthopaedics, sports medicine, physical medicine and rehabilitation, rheumatology, and primary care to offer an advanced, collaborative approach to your care.
What to Expect
Before treatment, you'll meet with an Interventional Radiology specialist to review your medical history, discuss your symptoms, and review your imaging.
Your provider will explain the procedure, discuss potential benefits and risks, and provide instructions about eating, drinking, and medications before your appointment.
During GAE, an interventional radiologist inserts a small catheter into an artery in the wrist or groin and guides it to the arteries that supply the inflamed areas of the knee. Tiny embolic particles are injected to reduce this abnormal blood flow while preserving normal circulation to healthy tissues.
The procedure typically takes one to two hours. Most patients return home the same day.
Recovery Timeline
After the procedure, you may experience
- Mild soreness at the catheter insertion site
- Temporary knee discomfort
- Bruising
- Fatigue
Most people resume normal daily activities within several days, although you may need to limit any strenuous activity for a week after the procedure.
You will likely start feeling pain relief within several weeks, and it usually continues to improve over the following months.

Frequently Asked Questions (FAQs)
No. GAE is not intended to replace knee replacement surgery for everyone. It may be an option for people who either want to delay surgery or are not good candidates for surgery.
Many patients experience pain relief that lasts months to years, although individual results vary.
Most procedures are done with moderate sedation, allowing you to remain comfortable without general anesthesia.
Depending on your symptoms and overall health, your provider will discuss whether one or both knees can be treated.
