Genicular Artery Embolization

What is Geniculate (Genicular) Artery Embolization?

Geniculate Artery Embolization is a non‑surgical procedure performed by an interventional radiology team. Through a pin‑sized opening—usually at the wrist or groin—a small catheter is guided to the arteries around the knee. Tiny beads are then used to reduce abnormal blood flow associated with inflammation. By calming this “overactive” circulation, many patients experience less pain and greater comfort with movement.

Who might be a candidate?

GAE may be appropriate if you:

• Have knee pain from osteoarthritis that limits daily activities

• Have not found adequate relief with activity changes, physical therapy, medications, or injections

• Are not ready for, prefer to delay, or are not a candidate for knee replacement

• Have been advised to explore minimally invasive options

GAE is not right for everyone. Certain types of advanced joint damage, active infections, or specific vascular conditions may make other treatments better suited. We’ll review your history and imaging to help you decide.

How the procedure works

1. Consultation & planning: We review your medical history, prior treatments, and knee imaging and discuss whether GAE fits your goals.

2. During GAE: After numbing the skin and providing relaxation medication as needed, a micro‑catheter is guided under X‑ray to the small arteries that supply the painful portions of your knee. Microscopic particles are delivered to reduce the abnormal inflammatory blood flow.

3. After GAE: A small bandage is placed at the access site. Most patients return home the same day with post‑procedure instructions.

Benefits patients often value

• Minimally invasive, no surgical incision into the knee joint

• Outpatient procedure with a small skin puncture

• Helps address the inflammatory driver of pain

• Can complement physical therapy and other conservative care

• May help reduce reliance on daily pain medications
  (Results vary from person to person.)

Recovery & results

It’s common to have mild soreness or bruising at the access site for a few days. Many people notice improvement within weeks, with full benefits continuing to build over time. We’ll outline activity guidelines and follow‑up so you know exactly what to expect as you heal.

Risks & considerations

All medical procedures carry risks. Possible risks with GAE include bleeding or bruising at the access site, temporary skin warmth or discoloration, numbness or tingling, allergic reaction to contrast dye, infection, vessel irritation, or non‑target embolization that could affect surrounding tissue. We’ll review your individual risks and answer all questions before moving forward.

How GAE compares to other options

GAE is different from genicular nerve ablation, which uses heat to interrupt pain signals. GAE instead targets the abnormal blood flow linked to inflammation. It also isn’t the same as knee replacement; some patients use GAE to delay or avoid surgery, while others may still choose surgery later. Your care plan is personalized to your needs.

Insurance & pricing

Coverage for GAE varies by plan. Our team will verify your benefits and discuss any out‑of‑pocket costs in advance, so there are no surprises. Medicare is accepted.
