Complete Guide to Genicular Artery Embolization
Genicular artery embolization (GAE) is a minimally invasive, image-guided procedure that helps reduce chronic knee pain associated with mild to moderate osteoarthritis, offering an alternative for patients who have not found adequate relief through conservative measures. If you are researching genicular artery embolization and wondering whether it could be right for you, this guide is designed to walk you through how the procedure works, who may be a candidate, what to expect during recovery, and why specialized vascular expertise matters.

What Is Genicular Artery Embolization and How Does It Work?
Genicular artery embolization is an interventional radiology procedure designed to interrupt abnormal blood vessel growth in the synovial lining of the knee joint. In knees affected by osteoarthritis, research suggests that the synovium becomes inflamed and develops an abnormal network of small blood vessels. This process, known as neovascularization, is associated with the nerve fibers that transmit pain signals. By selectively reducing blood flow to these abnormal vessels, genicular artery embolization decreases inflammation and, with it, the chronic pain that limits daily activity.
During the procedure, board-certified vascular interventional physician, Dr. Julien, accesses the arterial system through a tiny needle puncture, at the groin Using real-time fluoroscopic imaging, a thin catheter is guided through the arterial system to the genicular arteries surrounding the knee. Tiny embolic microspheres are then delivered precisely to the abnormal vessels responsible for inflammation, while the surrounding healthy tissue and normal blood supply remain protected.
The procedure is performed on an outpatient basis, meaning patients go home the same day. Patients return to their normal activities the same day as the procedure. Because genicular artery embolization (GAE) is a minimally invasive procedure that does not require general anesthesia or surgical incisions, it offers a different treatment and recovery experience compared to traditional knee replacement surgery or arthroscopic procedures. Individual results may vary, and a consultation with a qualified vascular specialist is the appropriate first step in determining candidacy. You can explore the full range of minimally invasive vascular treatments available at South Florida Vascular Associates to understand the breadth of care offered.
Who May Be a Candidate for Genicular Artery Embolization?
Genicular artery embolization is generally considered for adults with mild to moderate knee osteoarthritis who continue to experience chronic knee pain despite conservative treatments. Conservative measures nclude physical therapy, anti-inflammatory medications, corticosteroid injections, and activity modification. Patients who have not achieved satisfactory relief from these approaches, yet whose imaging does not indicate the level of joint degeneration that would require surgical replacement, may represent appropriate candidates for this procedure.
Common Patient Profiles
Research suggests that candidates include adults over the age of 40 with documented osteoarthritis on imaging, persistent knee pain lasting three months or more, and no active joint infection or severe vascular disease affecting the lower extremities. Patients who are not surgical candidates due to age, overall health status, or personal preference may also find genicular artery embolization worth discussing with a specialist.
Who May Not Be a Good Fit
Patients with advanced-stage osteoarthritis, bone-on-bone joint degeneration, or certain vascular conditions may not be well-suited for genicular artery embolization. Those with significant kidney impairment, allergy to contrast dye, or active infection near the treatment site would require additional evaluation before being considered. A thorough imaging review and consultation with a vascular interventional physician are necessary to determine whether this procedure aligns with an individual patient’s anatomy and health history. Individual results may vary based on the degree of joint involvement and overall health status.

Genicular Artery Embolization: What to Expect Before, During, and After
Understanding the full experience of genicular artery embolization helps patients approach the procedure with realistic expectations and confidence. The process begins with a comprehensive consultation and imaging review. Your vascular physician will evaluate X-rays or MRI imaging of the affected knee, review your medical history, and discuss your symptom pattern to determine whether GAE is an appropriate option.
Before the Procedure
Fasting instructions will be provided based on the planned sedation approach. Arrangements for transportation to home should be made, as patients will not drive themselves following the procedure.
During the Procedure
Genicular artery embolization is performed in a specialized suite using fluoroscopic guidance. A tiny needle puncture provides arterial access, and the catheter is navigated to the target vessels with precision. The entire procedure typically takes less than one hour. Patients are monitored throughout and receive appropriate sedation or local anesthesia to support comfort during the process.
After the Procedure
Patients go home the same day following genicular artery embolization and return to their normal activities the next day. Some degree of knee soreness or mild swelling in the days following the procedure is not uncommon, and your care team will provide specific guidance on activity, medications, and follow-up imaging. Research suggests that meaningful improvements in knee pain may be experienced within weeks to a few months following the procedure.

Frequently Asked Questions About Genicular Artery Embolization
Is genicular artery embolization FDA-approved?
The embolic microspheres used in genicular artery embolization are FDA-cleared devices. The procedure itself is performed as an off-label application of these approved materials, a common and accepted practice in interventional radiology. Research and clinical studies support its use for osteoarthritis-related knee pain, and a board-certified vascular interventional physician can review the current evidence with you during a consultation.
How long does it take to see results after genicular artery embolization?
Research suggests that patients may begin noticing improvements in knee pain within two to six weeks following genicular artery embolization, with continued improvement possible over the following months. The timeline varies based on the degree of joint involvement, overall health, and individual biology. Your vascular physician will outline what to expect at your follow-up appointments and what signs of progress to monitor.
Will insurance cover genicular artery embolization?
Coverage for genicular artery embolization varies by insurance plan and is evolving as clinical evidence continues to grow. Some major insurance carriers and Medicare plans may provide coverage depending on documented medical necessity and prior authorization requirements. South Florida Vascular Associates works with patients to navigate insurance questions during the consultation and scheduling process. Contacting your insurance provider in advance to confirm your specific benefit is also recommended.
Can genicular artery embolization be performed on both knees?
In some cases, both knees may be addressed, either during the same procedure session or in staged sessions, depending on the patient’s anatomy, overall health, and the extent of involvement in each joint. Dr. Julien will review imaging of both knees and discuss the most appropriate approach for your individual situation. A thorough pre-procedure consultation is the appropriate starting point for bilateral knee pain concerns.
