Genicular Artery Embolization (GAE) is a minimally invasive, outpatient procedure that may help relieve chronic knee pain caused by osteoarthritis by reducing abnormal inflammation in the knee. Instead of replacing the joint, GAE targets tiny blood vessels that contribute to ongoing pain and swelling. For the right patients, it can offer meaningful relief with a faster recovery than traditional knee surgery.
Chronic knee pain can make everyday activities difficult. Walking, climbing stairs, exercising, and even standing for long periods can become frustrating when osteoarthritis progresses.
Many patients are told their only options are medications, injections, or eventual knee replacement. However, there is a middle-ground solution. Genicular Artery Embolization offers a non-surgical approach to reducing knee pain and improving mobility.
At Colorado Advanced Endovascular (CAE), this procedure is part of a growing focus on minimally invasive treatments designed to help patients avoid or delay surgery whenever possible.
What Is Genicular Artery Embolization (GAE)?
Genicular Artery Embolization is a procedure performed by an interventional radiologist to treat knee pain caused by osteoarthritis. It targets inflammation in the knee joint by reducing blood flow to abnormal vessels that contribute to pain.
In osteoarthritis, the lining of the joint can become inflamed and develop excess blood vessels. These vessels sustain inflammation, swelling, and discomfort. GAE works by blocking these abnormal vessels while preserving healthy circulation to the rest of the knee.
How the GAE Procedure Works
GAE is performed using advanced imaging and does not require open surgery. The procedure is typically completed in an outpatient setting.
What happens during GAE:
- A small catheter is inserted through a tiny access point in the wrist or groin
- Imaging is used to guide the catheter to the arteries supplying the inflamed areas of the knee
- Tiny particles are injected to reduce blood flow to the abnormal vessels
As inflammation decreases, patients often experience gradual improvement in pain and function over the following weeks. Colorado Advanced Endovascular (CAE) specializes in these image-guided techniques, allowing patients to receive effective treatment without the need for major surgery.
How GAE Differs From Knee Replacement
GAE focuses on reducing pain without replacing the joint, making it very different from traditional surgery.
Here are a list of its benefits:
- No joint replacement or major surgery
- No large incisions
- Outpatient procedure
- Faster recovery time
- Lower overall risk
- Preserves the natural knee
Knee replacement considerations:
- Major surgical procedure
- Longer recovery and rehabilitation
- Increased downtime from work and activities
- Higher risks associated with surgery
For patients who want to avoid or delay knee replacement, GAE can provide a less invasive option for relief.
Who May Benefit From GAE?
GAE is typically recommended for patients with knee osteoarthritis who continue to experience pain despite conservative treatment.
You may be a candidate if you:
- Have chronic knee pain from osteoarthritis
- Have tried medications, injections, or physical therapy without relief
- Want to avoid or postpone knee replacement
- Prefer a minimally invasive treatment option
- Experience pain that limits daily activities
A consultation is needed to determine if GAE is appropriate for your condition and overall health.
What to Expect During Recovery
Recovery from GAE is generally quick compared to surgical options. Most patients go home the same day and resume normal activities soon after.
Typical recovery timeline:
- Day 1-2: Mild soreness or discomfort
- First week: Return to light activities
- Weeks 2-6: Gradual improvement in pain and mobility
- Ongoing: Continued relief as inflammation decreases
Because the procedure is minimally invasive, there is no long surgical recovery or extensive rehabilitation required.

Frequently Asked Questions
What is Genicular Artery Embolization?
Genicular Artery Embolization, or GAE, is a minimally invasive procedure used to treat chronic knee pain caused by osteoarthritis. It works by reducing blood flow to abnormal vessels that contribute to inflammation and pain in the knee.
Is GAE the same as knee replacement?
No. GAE does not replace the knee joint. It is a non-surgical procedure designed to reduce inflammation and pain while preserving the natural knee.
Who may be a good candidate for GAE?
Patients with chronic knee pain from osteoarthritis who have not found enough relief from medications, injections, or physical therapy may be candidates. A consultation is needed to determine if the procedure is appropriate.
How long does recovery take after GAE?
Most patients go home the same day and return to light activities soon after. Pain and mobility often improve gradually over several weeks as inflammation decreases.
Does GAE require general anesthesia?
GAE is typically performed as an outpatient procedure and does not require open surgery. Your care team will explain what type of sedation or anesthesia is appropriate for your case.
How soon will I feel relief after GAE?
Some patients notice improvement within a few weeks, while others experience gradual relief over several weeks as inflammation continues to decrease.
Can GAE help me avoid knee replacement?
GAE may help some patients avoid or delay knee replacement, depending on the severity of their osteoarthritis and overall condition.
Is GAE right for everyone with knee pain?
No. GAE is generally used for knee pain related to osteoarthritis. A medical evaluation is needed to confirm the cause of your pain and determine whether GAE is a good option.
