Chronic knee pain is one of the most common reasons adults seek medical care—and for many people, the cause is knee osteoarthritis. As cartilage wears down over time, inflammation increases, movement becomes painful, and daily activities like walking, climbing stairs, or sleeping comfortably can feel impossible.
For years, treatment options for knee osteoarthritis have existed at two extremes: conservative therapies like medications, physical therapy, and injections—or total knee replacement surgery. But what if you are stuck in the middle? What if injections no longer help, but surgery feels too invasive, too risky, or simply not the right time?
That’s where Genicular Artery Embolization (GAE) may offer a solution.
Understanding Knee Osteoarthritis and Inflammation
Knee osteoarthritis isn’t just a “wear and tear” problem. As arthritis progresses, the body forms abnormal blood vessels around the knee joint. These vessels fuel chronic inflammation by delivering inflammatory cells and chemical signals that worsen pain, swelling, and stiffness.
This inflammation becomes self-perpetuating—more blood flow leads to more inflammation, which leads to more pain.
GAE is designed to interrupt this cycle.
What Is Genicular Artery Embolization?
Genicular Artery Embolization is a minimally invasive, image-guided procedure that targets the abnormal blood flow contributing to knee inflammation.
Using advanced imaging, a vascular specialist identifies small branches of the genicular arteries—the vessels that supply blood to the knee joint—that are responsible for inflammatory signaling. Tiny particles are then delivered through a catheter to reduce abnormal blood flow while preserving healthy circulation.
The result: less inflammation, less pain, and improved function—without surgery.
How the GAE Procedure Works
GAE is performed as an outpatient procedure and typically takes about one to two hours.
Here’s what patients can expect:
- A small catheter is inserted through the wrist or groin
- Advanced imaging maps blood flow to the knee
- Abnormal inflammatory vessels are selectively embolized
- No incisions, stitches, or implants are required
- Patients go home the same day
Most patients resume light activities within days and experience gradual improvement over weeks to months as inflammation subsides.
Who Is a Good Candidate for GAE?
GAE may be an option if you:
- Have chronic knee pain caused by osteoarthritis
- Have tried physical therapy, medications, or injections with limited relief
- Are not ready for knee replacement
- Want to delay or avoid surgery
- Are a poor surgical candidate due to medical conditions
- Want a minimally invasive option with faster recovery
GAE does not replace knee replacement surgery—but it can be an important bridge or alternative for the right patient.
Benefits of GAE Compared to Surgery
Many patients are drawn to GAE because it offers several advantages over traditional surgery:
- No incisions or joint replacement
- Outpatient, same-day procedure
- Local anesthesia (no general anesthesia required)
- Minimal downtime
- Preserves future surgical options
- Lower procedural risk for appropriate candidates
Because GAE does not alter the joint structure, patients who later require knee replacement can still undergo surgery without limitation.
How Effective Is GAE?
Clinical studies and real-world outcomes show that many patients experience:
- Significant reduction in pain
- Improved mobility and walking tolerance
- Decreased reliance on pain medications
- Improved quality of life
Results vary based on the severity of arthritis, activity level, and individual anatomy, which is why a personalized evaluation is critical.
Why Vascular Expertise Matters
GAE requires advanced imaging, precise vascular navigation, and deep understanding of blood flow patterns. That’s why it should be performed by specialists with dedicated expertise in embolization procedures.
At Vascular Institute of Chattanooga, patients benefit from:
- Specialized embolization experience
- Advanced imaging technology
- Collaborative care with referring providers
- Rapid access to evaluation and treatment
Is GAE Right for You?
If knee pain is limiting your ability to live fully—and conservative treatments are no longer working—GAE may offer a minimally invasive path forward.
An evaluation can help determine whether Genicular Artery Embolization fits your symptoms, goals, and overall health.
