Genicular Artery Embolization (GAE)
1. What is Genicular Artery Embolization (GAE)?
Genicular Artery Embolization (GAE) is a medical procedure used to treat knee pain, especially in patients with osteoarthritis (a type of joint disease). It involves blocking certain blood vessels (genicular arteries) that supply blood to the painful area of the knee. By reducing the blood flow to the painful tissues, the procedure helps to decrease inflammation and pain in the knee.
2. Why would someone need this procedure?
People who suffer from chronic knee pain due to osteoarthritis or other knee problems, and who haven’t found relief from other treatments like medication or physical therapy, might need GAE. It’s especially useful when the pain is caused by inflammation in the knee.
3. How does GAE work?
During the procedure, doctors use a small tube called a catheter, which is inserted into a blood vessel in the leg (often near the groin). They guide the catheter to the genicular arteries that supply blood to the knee. Then, tiny particles are injected into these arteries to block the blood flow to the painful areas, reducing inflammation and pain.
4. Is GAE safe?
GAE is generally considered safe, but like any medical procedure, it carries some risks. Potential risks include infection, bleeding, or allergic reactions to the contrast dye used in imaging. However, serious complications are rare. Your doctor will assess your overall health to determine if you’re a good candidate for the procedure
5. How effective is GAE?
Many patients experience significant pain relief after GAE, especially those with knee pain caused by osteoarthritis. The effects can last from several months to over a year, depending on the individual. Some people may need more than one procedure over time, while others find long-term relief after just one session.
6. What are the benefits of GAE?
GAE has several advantages over traditional knee surgery:
- Minimally invasive: There’s no need for large incisions or lengthy hospital stays.
- Shorter recovery time: Many patients can go back to normal activities within a few days.
- Less risk: Because it’s a non-surgical procedure, there’s a lower risk of complications like infection or blood clots.
7. Who is a good candidate for GAE?
People who have chronic knee pain due to osteoarthritis or other inflammatory conditions are often candidates for GAE. However, the procedure is usually recommended for patients who haven’t responded well to conservative treatments (like medications, physical therapy, or corticosteroid injections) and are looking for an alternative to surgery
