GENICULATE ARTERY EMBOLIZATION

Minimally Invasive Relief for Knee Pain Caused by Osteoarthritis

Geniculate Artery Embolization (GAE) is a cutting-edge, minimally invasive treatment offered at DFW Surgical Partners for patients suffering from knee pain due to osteoarthritis. This innovative procedure targets the small arteries surrounding the knee that become inflamed in arthritis, blocking abnormal blood flow that contributes to pain and inflammation.

How It Works

Using advanced imaging guidance, our vascular specialists insert a tiny catheter through a small incision in the groin or wrist. Microscopic particles are then injected to selectively block the inflamed arteries around the knee joint. This reduces inflammation and pain — often without the need for surgery or joint replacement.

Benefits of Geniculate Artery Embolization

  • Minimally invasive and outpatient-based
  • Reduces knee pain and inflammation
  • Quick recovery with minimal downtime
  • Preserves joint structure and function
  • Ideal for patients who are not candidates for knee replacement surgery

Our expert vascular team combines interventional precision with compassionate care, helping patients regain mobility and quality of life. GAE is performed in our state-of-the-art outpatient surgical suite, providing safe, comfortable, and efficient care with proven results.

How GAE works

A catheter is guided into small knee arteries; tiny particles reduce abnormal inflammatory blood flow.

Common indications

Adults with knee osteoarthritis pain linked to inflammation who have not achieved relief with medications, physical therapy, or injections.

Who may not qualify

Active infection, severe peripheral arterial disease of the leg, or conditions that make angiography unsafe. Your evaluation determines candidacy.

Team approach

We coordinate with orthopedic and pain specialists to ensure GAE fits your overall knee care plan.

What to expect

During the procedure

  • Usually performed with local anesthesia and light sedation.
  • Tiny catheter inserted through a wrist or groin artery and guided to knee vessels.
  • Microspheres are released to reduce abnormal inflammatory flow.

After the procedure

  • Most patients go home the same day; mild soreness or skin warmth may occur.
  • Walking is encouraged; avoid heavy activity for a few days per instructions.
  • Pain relief can begin within weeks as inflammation calms; results vary.

Potential benefits

  • Minimally invasive outpatient option
  • Targets inflammation to help reduce pain
  • Can complement other knee therapies

Risks/considerations

  • Bruising, temporary skin blush/warmth, or mild pain flare
  • Allergic reaction to contrast dye (uncommon)
  • Very rare risk of non‑target embolization or skin injury—careful imaging reduces this risk

Aftercare

  • Hydration to flush contrast; keep puncture site clean and dry.
  • Resume light activity as tolerated; avoid strenuous exercise for several days.
  • Follow‑up visit to monitor symptom change and plan next steps.

Frequently asked questions

Is GAE a replacement for knee replacement surgery?
Not necessarily. GAE is one option in a spectrum of knee treatments. Some patients may still need surgery; others may find relief that postpones or avoids it. Decisions are individualized.
Some patients report early relief within weeks; others improve gradually over a few months as inflammation subsides.
Most procedures use local anesthesia with light sedation so you’re relaxed and comfortable.
