Geniculate Artery Embolization (GAE) for Chronic Knee Pain
Innovative Relief for Chronic Knee Pain
If you’re living with chronic knee pain from osteoarthritis, and conservative treatments like physical therapy, injections, or medications haven’t provided lasting relief, there’s a breakthrough option that doesn’t require knee replacement surgery. It’s called Geniculate Artery Embolization (GAE) – a minimally invasive procedure that targets the source of your pain.
Dr. Austin Bourgeois offers Geniculate Artery Embolization in Huntsville – an outpatient procedure that reduces knee inflammation and pain by blocking abnormal blood vessels around the knee joint, helping you regain mobility and delay or avoid the need for knee replacement surgery.
Dr. Bourgeois is the only interventional radiologist in Huntsville offering GAE. Patients no longer need to travel 100+ miles to Birmingham or Nashville
Is Knee Osteoarthritis Affecting Your Life?
- Chronic knee pain that worsens with activity
- Stiffness, especially in the morning or after sitting
- Swelling and inflammation around the knee joint
- Reduced range of motion
- Difficulty climbing stairs or walking
- Pain that interferes with sleep
- Grinding or popping sensations
- Knee giving way or feeling unstable
If knee pain is limiting your activities, affecting your independence, or impacting your quality of life, geniculate artery embolization offers hope for relief without the extended recovery of knee replacement surgery.
What Is Geniculate Artery Embolization?
Geniculate artery embolization (GAE) is a minimally invasive treatment for chronic knee pain due to osteoarthritis, especially when conservative therapies fail and surgery is not desired. It reduces inflammation by blocking abnormal blood vessels around the knee that contribute to pain and swelling.
A catheter is placed in the femoral artery and advanced to the geniculate arteries supplying the knee lining. Tiny particles are injected to embolize these vessels, decreasing pain-causing inflammation. It’s an outpatient procedure lasting 45-90 minutes under conscious sedation.
Many patients report substantial pain reduction lasting months to years, improved mobility, and delayed need for knee replacement. Recovery is quick, with mild soreness possible.
Who is a Candidate?
GAE is ideal for:
Moderate to severe knee pain
from osteoarthritis affecting daily activities
Failed conservative treatments
like physical therapy, injections, or medications
Want to delay or avoid
knee replacement surgery
Seeking improved mobility
and quality of life without major surgery
Active duty military and defense professionals at Redstone Arsenal who cannot afford 3–6 months of surgical recovery
Too young for knee replacement — prosthetics last only 15–20 years, meaning revision surgery later
Benefits of Geniculate Artery Embolization
- Minimally invasive – no surgical incisions
- Outpatient procedure with same-day discharge
- Quick recovery – return to activities in days
- Significant pain reduction in most patients
- Improved knee mobility and function
- Zero major complications in the largest clinical study
- Recognized by the American Academy of Orthopaedic Surgeons
- Delays or eliminates need for knee replacement
- Lower risk than surgery
- Can be repeated if needed
Recovery & Results
Most patients go home the same day — typically within two to four hours of the procedure. A small bandage covers the puncture site in the upper thigh. Mild knee soreness lasting about a week is common and easily managed with over-the-counter ibuprofen. No physical therapy is required.
Pain scores typically drop from an average of 8 out of 10 to 3 out of 10 within the first week, with continued improvement over the following months. Approximately 70 percent of patients achieve at least 50 percent pain reduction. Maximum benefit develops over about six months as the inflammatory environment around the joint resolves. At two years, 72 percent of initial responders maintained their improvement, and only 5.2 percent progressed to knee replacement — meaning the vast majority successfully delayed or avoided surgery.
The most common side effect is temporary skin discoloration near the knee (approximately 11 percent of patients), which resolves on its own. Zero major complications were reported in the largest meta-analysis of 270 patients.
Frequently Asked Questions
Quick answers about GAE — with links to our in-depth guides for more detail.
GAE is a same-day outpatient procedure with 1–2 day recovery, no general anesthesia, and no alteration to the knee. Knee replacement requires hospital admission and 3–6 months of recovery. GAE provides 1–4 years of relief as a bridge — it does not replace knee replacement but can significantly delay or avoid it.
Read our full side-by-side comparisonYes. GAE is covered by Blue Cross Blue Shield of Alabama, Medicare, TRICARE, and most commercial plans. With Medicare and a Medigap supplement, out-of-pocket is often zero after the $240 deductible. Our team handles prior authorization.
See detailed cost and insurance informationMost patients go home the same day and return to desk work the next day. Normal activities resume within one to two days. No physical therapy is required. Compare this to 3–6 months of recovery after knee replacement.

See full data in our Complete GAE GuideYes. GAE makes no structural changes to the knee joint. Studies confirm successful knee replacement after prior GAE. GAE is specifically designed as a bridge that preserves all future options.
Learn more in our Complete GAE GuideWithout insurance, GAE costs $8,000 to $15,000 compared to $30,000–$50,000+ for knee replacement. With commercial insurance, typical out-of-pocket is $1,500 to $2,500. Medicare Advantage plans cover GAE for approximately $75.
