If you’ve been struggling with persistent knee pain from osteoarthritis, you’re not alone. Adults aged 45 and older who experience knee osteoarthritis often find limited relief from traditional treatments like medications, physical therapy, or injections. While many eventually face the prospect of knee replacement surgery, a revolutionary alternative is changing the treatment landscape: Genicular Artery Embolization (GAE).
GAE offers a minimally invasive path to lasting knee pain relief without the risks, lengthy recovery, and surgical trauma associated with traditional knee surgery. This breakthrough procedure is helping patients reclaim their mobility and quality of life through an outpatient treatment that takes just a few hours.
What Is Genicular Artery Embolization?
Genicular Artery Embolization is a minimally invasive procedure that treats chronic knee pain caused by osteoarthritis by reducing abnormal blood flow and inflammation in the knee joint. Unlike surgery that replaces or removes damaged joint tissue, GAE addresses the issues that cause osteoarthritis pain: synovial inflammation and abnormal blood vessel growth.
How GAE Works
Genicular Artery Embolization (GAE) is a minimally invasive procedure that targets one of the key sources of osteoarthritis pain — inflammation in the knee joint lining. When osteoarthritis develops, the synovial membrane (the soft tissue that lines the joint) can become inflamed and grow abnormal new blood vessels and pain-sensing nerves. These changes feed ongoing inflammation and increase pain sensitivity.
During the GAE procedure, an interventional radiologist makes a tiny incision, usually in the groin or wrist, and inserts a thin catheter into the bloodstream. Using advanced X-ray imaging, the doctor carefully guides the catheter to the genicular arteries, which supply blood to the knee joint. Once in position, microscopic embolic particles are gently released into these arteries. These particles block the abnormal small vessels that sustain inflammation in the joint. By reducing excess blood flow and calming pain-sensitive nerves, GAE helps decrease swelling and relieve pain.
The result is lasting pain reduction and improved knee function — all without removing any bone, cartilage, or healthy tissue.
The Benefits of GAE for Knee Osteoarthritis
Proven Pain Relief
Genicular Artery Embolization (GAE) has been shown in clinical studies to deliver lasting relief from knee pain and significant improvements in quality of life. Approximately 70-80% of patients experience significant pain reduction and improved function. Many patients report being able to walk longer distances, stay active, and return to their daily routines with greater comfort. Sleep quality often improves as nighttime pain decreases, and overall joint stiffness and inflammation are noticeably reduced.
GAE offers an effective, minimally invasive option for those seeking relief from chronic knee pain without surgery.
Minimally Invasive with Rapid Recovery
Unlike knee replacement surgery that requires large incisions, extended hospital stays, and months of rehabilitation, GAE is performed as an outpatient procedure. Most patients return home the same day with only a small bandage covering the catheter insertion site. Recovery is remarkably quick—many patients resume normal activities within one to two weeks, compared to the three to six months typically required after knee replacement.
No General Anesthesia Required
GAE is performed under moderate sedation, eliminating the risks associated with general anesthesia. This makes the procedure accessible to patients who might be considered high-risk surgical candidates due to age or other medical conditions like heart disease or diabetes.
Long-Lasting Results
Research shows that GAE provides sustained pain relief extending from 1-3 years or longer for many patients. For patients seeking to delay or avoid knee replacement surgery, GAE offers a durable solution that can provide years of improved function and quality of life.
Who Is a Candidate for GAE?
Genicular Artery Embolization (GAE) may be an excellent option for individuals seeking relief from chronic knee pain caused by osteoarthritis — especially when other treatments haven’t provided lasting results.
You may be a good candidate if you:
Have mild to moderate knee osteoarthritis (Kellgren–Lawrence grade 2–3)Experience persistent knee pain despite conservative treatmentsHave not found adequate relief from physical therapy, anti-inflammatory medications, or cortisone injectionsWish to avoid or delay knee replacement surgeryAre not a surgical candidate due to other medical conditionsHave preserved joint structure but ongoing pain from inflammation
Patients with more advanced osteoarthritis can still experience benefits from GAE, though outcomes are often more durable in earlier stages of the disease.
During your consultation, an interventional radiologist will review your imaging studies and medical history to determine whether GAE is the most appropriate treatment for your condition.
The GAE Procedure: What to Expect
Before Your Procedure
Your interventional radiologist will review your medical history, current medications, and imaging studies. You’ll receive detailed instructions about preparing for the procedure, including when to stop eating and drinking. Blood tests may be ordered to ensure your body can safely process the contrast dye used during imaging.
During the Procedure
On the day of your treatment, you’ll receive moderate sedation to keep you comfortable but awake. The interventional radiologist will numb the access site (typically your groin or wrist) and make a tiny puncture to insert the catheter. Using real-time X-ray guidance, the catheter is advanced to the genicular arteries supplying your knee.
Contrast dye is injected to visualize the blood vessels and identify the abnormal vessels contributing to your pain. Once identified, embolization material is carefully delivered through the catheter to block these vessels. The entire procedure typically takes one to two hours.
After the Procedure
Following the GAE procedure, you’ll rest in a recovery area for several hours while medical staff monitor you. Most patients experience minimal discomfort and are discharged home the same day with specific care instructions. You’ll be advised to avoid strenuous activities for a few days, but most people can walk immediately after the procedure.
Recovery and Results Timeline
Pain relief from GAE typically begins within one to two weeks as inflammation in the knee joint subsides. Many patients notice gradual, continued improvement over the following two to three months. During this time, the abnormal blood vessels remain blocked while your body’s normal circulation adapts to maintain healthy knee tissue.
You can expect to return to work within a few days, depending on your job’s physical demands. Low-impact activities like walking can usually resume almost immediately, while higher-impact activities may need to wait a few weeks. Your interventional radiologist will provide personalized guidance based on your recovery progress.
