Chronic knee pain caused by osteoarthritis (OA) can severely impact mobility and quality of life. Many patients with knee osteoarthritis experience persistent pain and swelling, even after trying physical therapy, medication, and injections. For those who want to avoid or delay knee replacement surgery, Genicular Artery Embolization (GAE) is an innovative, minimally invasive procedure that reduces inflammation and provides lasting knee pain relief.
At Vascular Surgery Associates, our specialized vascular surgeons in Los Angeles and Santa Monica offer GAE as a non-surgical option for patients suffering from osteoarthritis-related knee pain. This advanced procedure improves mobility, restores comfort, and enhances daily function without the need for invasive surgery.
What is Genicular Artery Embolization (GAE)?
GAE is a minimally invasive, image-guided procedure that targets the inflamed blood vessels responsible for pain and swelling in osteoarthritic knees. The goal of the procedure is to reduce excess blood flow to the knee joint, which in turn decreases inflammation and alleviates pain.
How the Procedure Works
- A small catheter is inserted into the artery through a tiny puncture in the groin or wrist.
- Using real-time imaging, the catheter is guided to the genicular arteries, which supply blood to the knee.
- Tiny particles are injected into the inflamed arteries to block excess blood flow and reduce inflammation.
- The catheter is removed, and the small puncture site is bandaged–no stitches required.
The entire procedure takes about 1 to 2 hours, and most patients go home the same day.
Who is a Candidate for GAE?
GAE is an excellent option for patients who:
- Have chronic knee pain from osteoarthritis (OA) that has not responded to other treatments
- Want to avoid or delay knee replacement surgery
- Experience swelling and inflammation in the knee joint
- Have difficulty walking or performing daily activities due to knee pain
- Have been told they are not candidates for knee surgery
Our vascular specialists at Vascular Surgery Associates evaluate each patient’s medical history, imaging results, and symptom severity to determine if GAE is the best treatment option.
