A thin catheter is placed
A small tube enters an artery through a tiny access point, usually in the wrist or groin.

Knee osteoarthritis care
Another option to discuss for persistent knee pain.
Genicular artery embolization, also called GAE or knee embolization, is an image-guided procedure that targets abnormal blood flow associated with inflammation in the lining of the knee.
It may help manage pain from knee osteoarthritis when treatments such as medication, physical therapy, or injections have not provided enough relief.
GAE does not replace the joint or rebuild worn cartilage. An evaluation helps determine whether it fits your symptoms, imaging, and treatment goals.
How GAE works
A targeted procedure through a small access point.
Using real-time imaging, the physician guides treatment to selected blood vessels around the knee. The joint itself is not opened.
Selected arteries are located
X-ray imaging and contrast dye help identify vessels supplying the inflamed knee lining.
Abnormal blood flow is reduced
Tiny particles are delivered to selected vessels, aiming to reduce inflammation and related pain.
Understanding your choices
GAE and knee replacement serve different needs.
An orthopedic assessment may still be important. GAE aims to manage symptoms; knee replacement addresses damaged joint surfaces.
| What to compare | GAE | Knee replacement |
|---|---|---|
| Approach | Catheter treatment of selected blood vessels; no joint implant | Surgery to replace damaged joint surfaces with implants |
| Access | Small arterial puncture, usually at the wrist or groin | Incision over the knee |
| Anesthesia | Often local anesthesia with sedation; plan varies | General anesthesia or a spinal/epidural technique |
| Stay | Typically an outpatient procedure with same-day discharge | Same-day discharge or a hospital stay, depending on the patient |
| Recovery | Initial recovery is generally shorter, with access-site care and activity restrictions | Rehabilitation and recovery typically extend over weeks to months |
This is a general comparison, not a recommendation for one treatment over another. Your clinicians should explain the options appropriate for you.
What to expect
Start with an evaluation and a clear plan.
Review symptoms and imaging
Your clinician reviews your knee pain, prior treatments, and health history. X-rays or other imaging may be needed to confirm the cause and assess suitability.
Receive image-guided treatment
GAE often takes one to two hours, with additional preparation and recovery time. Your team explains sedation, access-site care, and discharge criteria.
Recover and follow up
Most patients go home the same day after observation. Arrange a driver and follow your individual instructions for activity, medications, and follow-up.
Risks & recovery
Understand the risks and recovery.
Possible side effects and risks
Bruising or soreness at the access site, temporary knee discomfort, and skin discoloration can occur. Risks also include bleeding, infection, and unintended embolization that may injure nearby tissue.
Your clinician will review your personal risks, including issues related to contrast dye, circulation, and other health conditions.
Results vary
Improvement, when it occurs, may develop gradually. Some patients have limited or no relief, and further treatment may be needed.
Follow your care team’s guidance on returning to daily activities and exercise. GAE does not cure osteoarthritis or guarantee that you will avoid knee replacement.
Insurance & consultation
Verify your coverage before scheduling.
Coverage for genicular artery embolization varies by insurance plan. Contact Peak Health Surgicare and your insurer to verify coverage, network participation, prior authorization, and estimated out-of-pocket costs.
Ask whether physician, facility, imaging, and anesthesia services are billed separately.
Common questions
Learn more about GAE.
Is GAE a type of knee surgery?
GAE is a minimally invasive, image-guided vascular procedure. A catheter is placed through an artery; the knee joint is not opened and no joint implant is inserted.
How long does pain relief last?
The degree and duration of relief vary. Evidence continues to evolve, and some patients do not improve. Discuss realistic expectations and the possibility of additional treatment with your clinician.
How soon can I resume normal activities?
Recovery depends on your health, the access site, and the procedure. Your team will explain restrictions on lifting, strenuous activity, and driving, and when you can return to your usual routine.
Can both knees be treated?
Your clinician can assess each knee and discuss whether treating one or both knees is appropriate, including the timing of treatment.
Does GAE replace knee replacement for everyone?
No. Some people need joint replacement or another treatment. GAE may be considered for selected patients who want to explore alternatives or are not suitable candidates for replacement.
