Genicular Artery Embolization (GAE) in Manhattan
For many New Yorkers living with chronic knee pain—especially due to osteoarthritis—the traditional options have been limited: medications, injections, physical therapy, or eventually invasive knee replacement surgery. Genicular Artery Embolization (GAE) is an advanced, minimally invasive alternative designed to reduce inflammation, improve mobility, and significantly relieve pain without the risks of major surgery.
At Fox Vein and Vascular, GAE is performed by David Fox, MD, FACS, RPVI a board-certified vascular surgeon with over 28+ years of experience performing image-guided, minimally invasive vascular procedures.

What Is Genicular Artery Embolization (GAE)?
Genicular Artery Embolization (GAE) is a minimally invasive procedure used to reduce chronic knee pain caused by osteoarthritis. Instead of replacing the knee joint, GAE targets the abnormal blood vessels that develop around inflamed knee tissue and contribute to ongoing pain and swelling.
During the procedure, a small catheter is guided through the arterial system using advanced imaging technology. Tiny embolic particles are then delivered into specific genicular arteries surrounding the knee. These particles reduce excess blood flow feeding the inflamed synovial lining, which may decrease inflammation, stiffness, and pain over time.
GAE is performed without large incisions, joint replacement hardware, or removal of cartilage or bone. Most patients return home the same day and resume light activity within a few days.
- are not ready for knee replacement surgery
- have not responded well to physical therapy, injections, or medications
- want a non-surgical treatment option
- are trying to stay active while managing osteoarthritis symptoms
At Fox Vein & Vascular, Dr. David Fox performs GAE using real-time vascular imaging and minimally invasive catheter techniques developed through decades of vascular intervention experience.
How Does GAE Work?
Osteoarthritis does not only affect cartilage inside the knee joint. In many patients, the body also develops abnormal inflammatory blood vessels around the knee capsule and synovial tissue. These vessels contribute to chronic inflammation, swelling, and pain signaling.
GAE works by targeting these abnormal vessels directly.
Using live fluoroscopic imaging, Dr. Fox guides a microcatheter through the arterial system to the genicular arteries surrounding the knee. Once the inflamed vessels are identified, microscopic embolization particles are carefully injected to reduce excess blood flow to the affected tissue.
The goal is not to block normal circulation to the knee. Instead, the procedure selectively decreases the abnormal inflammatory blood supply associated with osteoarthritis pain.
Step-by-Step Overview
1. Access
A small entry point is created, usually near the groin or ankle, to access the arterial system. No surgical incision or stitches are typically required.
2. Catheter Navigation
A thin catheter is advanced through the blood vessels using real-time X-ray imaging guidance.
3. Embolization
Tiny embolic particles are delivered into targeted genicular arteries associated with inflammation.
4. Completion
The catheter is removed and a small bandage is applied. Most procedures take approximately 45–90 minutes.
Most patients go home the same day.
Who Is a Good Candidate for GAE?
GAE is ideal for patients with knee osteoarthritis, especially if they:
- Experience persistent knee pain despite conservative treatments
- Are not ready or not suitable for knee replacement
- Want to avoid steroid injections or cannot receive them
- Prefer a minimally invasive treatment option
- Have failed physical therapy, NSAIDs, viscosupplementation (hyaluronic acid, gel injections, Synvisc, Orthovisc, etc), or PRP
- Have chronic pain that limits daily activities or physical therapy
GAE may NOT be ideal for patients with:
- Active joint infection
- Severe peripheral arterial disease
- End-stage bone-on-bone degeneration; a patient may benefit from imaging review (less likely to work, but we can try it)
A consultation with Dr. Fox—including diagnostic ultrasound and a review of imaging studies—is the best way to determine candidacy.
Why Patients Are Considering GAE Instead of Knee Replacement
Many patients researching Genicular Artery Embolization are trying to delay, avoid, or better prepare for knee replacement surgery. While knee replacement remains an important option for advanced osteoarthritis, not every patient is ready for a major orthopedic procedure.
GAE offers a non-surgical alternative that may help reduce pain and improve mobility without joint replacement, implanted hardware, or extended surgical recovery.
Patients commonly explore GAE when they:
- still want to stay active
- have persistent pain despite injections or therapy
- are not ideal surgical candidates
- want to postpone knee replacement
- are concerned about recovery time after orthopedic surgery
Unlike arthroscopic surgery or total knee replacement, GAE is performed through a tiny catheter using image-guided vascular techniques. Most patients return home the same day.
For some patients, GAE may provide meaningful symptom relief while helping preserve mobility and quality of life.
Clinical Research and Outcomes
Genicular Artery Embolization has been studied as a minimally invasive treatment option for knee osteoarthritis in patients with chronic pain that has not responded to conservative therapy.
- reductions in knee pain scores
- improved mobility and daily function
- lower inflammation within the treated knee
- sustained symptom improvement in many patients over 12–24 months
GAE continues to gain attention among interventional radiologists and vascular specialists as interest grows in non-surgical osteoarthritis treatment options.
While outcomes vary by patient and severity of arthritis, many individuals experience meaningful improvement without undergoing knee replacement surgery.
Benefits of Genicular Artery Embolization
Patients choose GAE because it offers:
Minimally invasive treatment—no incisions
Outpatient procedure with same-day discharge
Rapid recovery (often within days)
Significant reduction in pain and inflammation
Non-surgical alternative to joint replacement surgery
No metal implants or removal of tissue
Lower risk than orthopedic surgery
Sustained pain relief lasting 12–24+ months
GAE vs. Other Knee Pain Treatments
| Treatment | Invasiveness | Duration of Relief | Ideal For |
|---|---|---|---|
| GAE | Minimally invasive, catheter-based | Often long-term | OA patients who wish delay or avoid knee replacement surgery |
| Steroid injections | Minimally invasive | Weeks–months | Short-term relief |
| Hyaluronic acid injections | Minimally invasive | Variable | Mild–moderate OA |
| PRP/Stem cell therapy | Minimally invasive | Under study | Some early-stage cases |
| Arthroscopic surgery | Moderately invasive | Limited for OA | Mechanical tears, not OA |
| Total knee replacement | Major surgery | Long-term but major recovery | Severe OA only |
What to Expect During Your GAE Procedure
Before the Procedure
