Genicular artery embolization is a minimally invasive procedure being used for selected patients with pain related to knee osteoarthritis. It does not rebuild cartilage or correct every mechanical problem. Its goal is to reduce abnormal blood flow associated with inflammation around an arthritic knee.
Start with the cause of pain
Knee pain can come from osteoarthritis, meniscal injury, tendon problems, instability, referred pain, inflammatory disease, infection, or other causes. A procedure aimed at osteoarthritis-related inflammation makes sense only after the pain source has been evaluated.
What GAE does
An interventional radiologist uses angiography to identify small genicular arteries supplying areas of abnormal inflammatory blood flow. Tiny particles are delivered selectively to reduce that flow while preserving the normal circulation needed by the knee.
Where it may fit
GAE may be discussed when imaging and symptoms support knee osteoarthritis and conservative treatments have not produced acceptable relief.
- Symptoms and imaging point to osteoarthritis
- Pain limits walking, activity, or sleep
- Medication, therapy, or injections have been reviewed
- The patient wants to understand options before or instead of surgery
- The clinical team believes the vascular anatomy and overall health are appropriate
What it does not do
GAE does not replace cartilage, repair a torn ligament, correct severe deformity, or guarantee that joint replacement will never be needed. Ask your specialist what GAE can and cannot improve in your case.
Recovery and follow-up
Most patients go home the day of treatment. Temporary soreness, bruising, or skin discoloration may occur. At follow-up visits over the next several weeks, your team asks about pain, walking, and everyday activities.
Frequently asked questions
Can GAE help bone-on-bone arthritis?
Severity on an X-ray is only one factor. Symptoms, alignment, stability, prior treatment, and other knee problems all matter. Some advanced cases are better addressed surgically.
Will insurance cover GAE?
Coverage varies. Some plans consider GAE investigational or require specific documentation. Benefits should be reviewed before scheduling.
Can I walk after GAE?
Many patients can walk soon after the access-site observation period, but the treating team provides individualized activity instructions.
