Chronic knee pain affects millions of adults in the U.S., often making it difficult to walk, exercise, or enjoy everyday activities. For many, the underlying cause is inflammation from osteoarthritis — a condition that wears down the cartilage protecting the knee joint. While surgery and joint replacement were once the only options for long-term relief, a new minimally invasive procedure called Genicular Artery Embolization (GAE) is changing the way patients manage knee pain.
What Is Genicular Artery Embolization?
Genicular Artery Embolization is an advanced, image-guided procedure performed by an interventional radiologist. Instead of removing tissue or replacing joints, the specialist targets the genicular arteries—small blood vessels that supply the inflamed areas of the knee. During GAE, a tiny catheter is inserted through a pin-sized incision, usually in the upper thigh. Using X-ray guidance, the physician injects microscopic particles that block abnormal blood flow to the inflamed joint lining (synovium).
By reducing excessive blood flow, GAE helps calm inflammation, relieve pain, and restore normal movement—without the need for stitches, hospital stays, or long recovery times.
Benefits of GAE
One of the biggest advantages of Genicular Artery Embolization is that it offers lasting relief without surgery. Many patients begin noticing improvement within days or weeks, with continued reduction in pain over several months.
Other key benefits include:
- Minimally invasive: Only a small puncture is required, with no large incisions or stitches.
- Outpatient procedure: Most patients go home the same day.
- Quick recovery: Many return to normal activities within a few days.
- Preserves joint structure: GAE treats inflammation rather than replacing the joint.
- Covered by insurance: Most major insurance providers now recognize and cover GAE.
Who Is a Candidate for GAE?
GAE is ideal for patients with chronic knee pain caused by osteoarthritis who have not found relief from conservative treatments like pain medication, physical therapy, or steroid injections. It is also an excellent alternative for those who are not ready—or not eligible—for knee replacement surgery due to age, health, or personal preference.
During a consultation, an interventional radiologist will evaluate your medical history, imaging results, and pain levels to determine if GAE is the best option for you.
What to Expect After Treatment
Most patients experience minimal discomfort after the procedure. Mild soreness around the puncture site may occur but typically resolves within a few days. Over time, as inflammation decreases, patients report significant improvements in mobility and quality of life.
