What is Genicular Artery Embolization?
Genicular Artery Embolization (GAE) is a minimally invasive, image-guided procedure used to reduce chronic knee pain caused by osteoarthritis. The treatment works by decreasing abnormal inflammation within the knee joint through targeted reduction of blood flow to inflamed tissues.
GAE is performed by an interventional radiologist using advanced imaging technology, allowing treatment without open surgery or joint replacement.
How the Procedure Works
- A small catheter is inserted through a tiny incision, usually in the wrist or groin.
- Imaging guidance is used to navigate to the genicular arteries around the knee.
- Microscopic particles are delivered to reduce blood flow to inflamed areas.
- Inflammation decreases, helping relieve pain and improve mobility.
Who May Benefit from GAE?
GAE may be appropriate for patients who:
- Have knee osteoarthritis causing chronic pain
- Have not found relief from medications or injections
- Want to delay or avoid knee replacement surgery
- Are not ideal candidates for surgery
- Experience persistent inflammation and swelling
Benefits of Genicular Artery Embolization
- Minimally invasive outpatient procedure
- No general anesthesia required
- Small incision with minimal scarring
- Short recovery time
- Reduced knee pain and improved function
- Preserves future treatment options
Recovery and Results
Most patients return home the same day. Mild soreness or fatigue may occur for a few days, but normal activities can typically resume quickly. Pain relief often begins within weeks and may continue improving over several months as inflammation decreases.
Risks and Considerations
GAE is generally safe, but as with any medical procedure, risks may include bruising, temporary discomfort, or rare vascular complications. A consultation with a qualified specialist is necessary to determine if GAE is right for you.
