What Is Genicular Artery Embolization (GAE)?
Genicular Artery Embolization is a non-surgical treatment that targets the tiny arteries (genicular arteries) supplying the inflamed areas of the knee joint. By blocking excess blood flow with microscopic particles, inflammation is reduced—relieving pain and improving function.
GAE is particularly beneficial for patients with:
-
Knee osteoarthritis pain not relieved by medications, physical therapy, or injections
-
Persistent knee inflammation
-
Early to moderate osteoarthritis
-
Surgical risks or preference to avoid joint replacement
Benefits of GAE at IVIRA
Patients from Pittsburgh and surrounding communities turn to IVIRA for state-of-the-art, patient-centered care. With extensive expertise in image-guided procedures, our interventional radiologists offer:
-
A nonsurgical solution to chronic knee pain
-
Outpatient treatment—no hospital stay or general anesthesia
-
Lower risk of infection and faster recovery than surgery
-
Pain relief often seen within 2 to 4 weeks
-
Improved quality of life without disrupting daily routines
What to Expect During the Procedure
GAE is performed under light sedation and local anesthesia in our outpatient vascular suite. Using real-time fluoroscopy (X-ray guidance), a small catheter is inserted into the femoral artery, then advanced into the genicular arteries of the knee.
Tiny embolic particles are released to selectively block abnormal blood flow contributing to inflammation and pain. The procedure typically takes 1–2 hours, and patients go home the same day.
Recovery & Results
procedure soreness, which resolves quickly. Many patients notice a reduction in pain and stiffness within 2–4 weeks, with continued improvement over several months.
Clinical studies show that GAE can reduce knee pain for 6–12 months or longer, making it an excellent bridge or alternative to surgery.
