Genicular Artery Embolization (GAE)

Chronic knee pain from osteoarthritis can make everyday activities, like walking, climbing stairs, or even standing, feel exhausting. Genicular artery embolization (GAE) is a minimally invasive procedure that relieves knee pain by reducing joint inflammation. For many patients, GAE provides significant results without surgery or a long recovery period.

If knee pain is limiting your mobility or independence, understanding osteoarthritis and how knee embolization works allows you the chance to learn more about effective, non-surgical treatment like GAE.

Understanding Knee Osteoarthritis

Osteoarthritis is a degenerative joint disease that occurs when the cartilage that cushions the ends of your bones wears away over time. This protective layer begins to wear away, causing the bones to rub against each other and eventually leading to pain, stiffness, swelling, and a limited range of motion in the affected joint.

Cartilage breakdown is only part of the problem, as osteoarthritis also inflames the joint’s lining as well. This inflammation increases blood flow to the joint, worsening swelling and pain. Over time, symptoms may progress to the point where daily activities become difficult.

Osteoarthritis is most common in the knees, hips, and hands. It is often associated with aging, as the cartilage in our joints naturally deteriorates over time. However, other factors, such as obesity, injuries, and genetics, can also increase risk if osteoarthritis is left untreated.

Treatment for chronic knee pain can help provide effective relief and prevent long-term complications. Untreated osteoarthritis can lead to symptom progression, increasing discomfort, and limiting mobility.

What Is Genicular Artery Embolization?

Genicular artery embolization is a minimally invasive procedure for treating chronic knee pain caused by osteoarthritis. The GAE procedure reduces abnormal blood flow to inflamed areas of the knee joint, decreasing inflammation and pain. An interventional radiologist performs the treatment using advanced imaging technology, such as X-ray fluoroscopy, as a guide. Unlike knee replacement surgery, genicular artery embolization for knee pain does not require general anesthesia, large incisions, or a hospital stay.

GAE is typically used to treat chronic knee pain related to osteoarthritis, particularly in patients who have not found adequate relief from medications, physical therapy, or injections. By targeting inflammation directly, genicular arterial embolization addresses one of the key drivers of knee osteoarthritis symptoms, preserving joint function and improving overall quality of life.

How the Genicular Artery Embolization Procedure Works

Genicular Artery Embolization (GAE) is a minimally invasive, outpatient procedure used to treat chronic knee pain caused by osteoarthritis by targeting inflammation inside the joint. During the procedure, a specialist guides a thin catheter through a small artery—usually in the wrist or upper thigh—to reach the tiny blood vessels around the knee that contribute to inflammation. Tiny particles are then released to reduce abnormal blood flow in those vessels, helping decrease inflammation and relieve pain over time. Because GAE does not involve surgery or large incisions, most patients can return to normal activities within a few days, making it an option for those seeking relief without joint replacement.

Benefits of Genicular Artery Embolization

Patients often consider GAE because it offers:

Minimally invasive procedure
GAE is performed through a small catheter inserted into an artery, which means no large incisions, stitches, or significant tissue disruption.
No general anesthesia required
The procedure is typically done using local anesthesia and light sedation, helping patients avoid the risks and longer recovery associated with being fully asleep.
Outpatient treatment
Patients can go home the same day, without the need for an overnight hospital stay.
Shorter recovery time
Most people return to light daily activities within 24–48 hours, with fewer limitations compared to surgical recovery.
Reduced knee pain and inflammation
GAE targets the blood flow contributing to inflammation in the knee, which may help decrease pain over time.
No implants or hardware
Unlike knee replacement, GAE does not involve artificial joints or implanted materials.
Option for patients not ready for surgery
GAE may be a suitable alternative for individuals who want to delay or avoid knee replacement or who are not candidates for surgery.
Preserves the natural joint
Because it does not alter the structure of the knee, GAE maintains your existing joint while addressing symptoms.

Together, these benefits position GAE as a promising option for patients looking for effective, lower-risk relief from chronic knee pain.

What to Expect During GAE Recovery

Recovery after Genicular Artery Embolization (GAE) is typically straightforward, especially compared to surgical options for knee osteoarthritis. Because the procedure is minimally invasive and performed without general anesthesia, most patients are able to go home the same day and begin light movement shortly after.

In the first 24 to 48 hours, you may notice mild soreness, swelling, or a warm sensation around the treated knee. These effects are usually temporary and can often be managed with over-the-counter pain relief and rest. Walking is encouraged soon after the procedure, and many patients are able to resume light daily activities within a day or two.

Over the next several days, it’s important to avoid strenuous activity, including heavy lifting, high-impact exercise, or deep knee bending. However, you won’t be confined to bed, and gentle movement can help support circulation and recovery.

Most patients gradually return to their normal routines within a few days, with continued improvement in knee pain developing over the following weeks as inflammation decreases. Your care team will provide personalized guidance to help ensure a smooth and effective recovery.

Are There Risks or Side Effects?

GAE is generally considered safe, but like any medical procedure, it carries some risks. These may include:

Temporary soreness or bruising at the access site
Mild skin discoloration near the knee (rare and usually temporary)
Limited risk of non-target embolization (minimized with imaging guidance)
Very low risk of blood clots – Rare but possible, reported risks include blood clots and vascular injury in approximately 0.6% of cases. GAE is safer than traditional knee surgery, which has a higher risk of DVT/PE requiring blood thinners

A specialist will review risks and benefits based on your individual health profile.

How Does GAE Work?

In osteoarthritis, tiny blood vessels around the knee (called genicular arteries) can become overactive and contribute to ongoing inflammation.

GAE works by:

Accessing a small artery (typically through the wrist or upper thigh)
Guiding a thin catheter to the arteries supplying the knee using imaging
Releasing tiny particles to reduce abnormal blood flow in those vessels
Decreasing inflammation, which can lead to pain relief over time

By targeting the source of inflammation, GAE addresses why the knee hurts, not just the symptoms.
