Genicular Artery Embolization: A Minimally Invasive Option for Chronic Knee Pain

April 16, 2026 Richmond Vascular Center

Chronic knee pain caused by osteoarthritis affects millions of adults and can significantly limit mobility, independence, and overall quality of life. For many patients, first-line treatments such as medications, injections, physical therapy, or lifestyle modifications provide only temporary relief. When symptoms persist, knee replacement surgery is often discussed, but surgery may not be the right choice for everyone.

Genicular Artery Embolization (GAE) is a minimally invasive, image-guided procedure that offers an alternative for patients with chronic knee pain who are seeking relief without surgery. By targeting the inflammation associated with osteoarthritis, GAE can help reduce pain and improve daily function while allowing patients to avoid or delay more invasive surgical treatments.

What Is Genicular Artery Embolization?

Genicular Artery Embolization is a procedure performed by an interventional radiologist to treat knee pain associated with osteoarthritis. Rather than operating on the joint itself, GAE targets abnormal blood flow that contributes to inflammation within the knee.

Using advanced imaging guidance, a thin catheter is inserted through a small access point, typically in the upper thigh, and carefully guided to the small arteries supplying the knee joint. Tiny particles are then delivered to selectively reduce abnormal blood flow, helping decrease inflammation and relieve pain.
Because the procedure is minimally invasive, it does not require large incisions or general anesthesia. All patients return home the same day and experience far less disruption to their daily routine compared with traditional surgical procedures.

Who May Be a Candidate for Genicular Artery Embolization (GAE)?

GAE may be an option for patients who:

• Experience chronic knee pain caused by osteoarthritis
• Have not found lasting relief from medications, injections, or physical therapy
• Want to delay or avoid knee replacement surgery
• Are not ideal surgical candidates due to age, health conditions, or personal preference

A consultation with an interventional radiologist, along with imaging and a review of medical history, is necessary to determine whether GAE is an appropriate treatment option for each individual patient.

What to Expect During the Procedure

Genicular Artery Embolization typically takes about an hour and is performed using local anesthesia and light sedation. Because the procedure uses only a small access point, there are no large incisions and no stitches are required.

During the procedure, the physician uses real-time imaging to guide a catheter through the blood vessels and deliver tiny particles that reduce the abnormal blood flow contributing to knee inflammation.

After a brief recovery period, patients return home the same day. Many people are able to resume normal daily activities within a short period of time, with minimal post-procedure discomfort.

Recovery and Results

Patients often begin to notice improvement in knee pain within days to weeks after the procedure, with continued improvement over several months as inflammation decreases.
Clinical studies have shown that Genicular Artery Embolization can provide meaningful and long-lasting pain relief for many patients with knee osteoarthritis. While results can vary from person to person, many patients report improved mobility and a greater ability to participate in everyday activities without relying as heavily on pain medications.

Because GAE addresses inflammation within the knee rather than replacing the joint, it can offer meaningful symptom relief while preserving future treatment options if they are needed later.

Benefits of Genicular Artery Embolization

For many patients, GAE offers several potential advantages compared to more invasive treatments, including:

• A minimally invasive approach with no large incisions
• A same-day outpatient procedure
• Shorter recovery time compared with knee replacement surgery
• Reduced knee inflammation and pain
• The potential to delay or avoid joint replacement surgery

These benefits make GAE an appealing option for patients seeking a less invasive way to manage chronic knee pain caused by osteoarthritis.

Why Interventional Radiology Matters

Genicular Artery Embolization is part of a growing field of minimally invasive treatments performed by interventional radiologists—physicians specially trained to diagnose and treat medical conditions using image guidance and catheter-based techniques.

At Richmond Vascular Center, interventional radiology procedures like GAE are performed in a dedicated outpatient environment designed around patient comfort, safety, and personalized care. The goal is to treat pain while helping patients return to daily activities with less disruption and faster recovery.

The Bottom Line

For patients experiencing chronic knee pain caused by osteoarthritis, Genicular Artery Embolization may offer a safe, minimally invasive treatment option worth considering—particularly for those who wish to avoid or postpone knee replacement surgery.

A consultation with an experienced interventional radiologist can help determine whether GAE is the right option and provide patients with a clearer understanding of their treatment choices moving forward.
