What is Genicular Artery Embolization (GAE)?
Genicular Artery Embolization (GAE) is a minimally invasive, image-guided procedure designed to reduce chronic knee pain caused by osteoarthritis. By blocking specific small arteries that supply blood to the inflamed synovial tissue in the knee, GAE reduces inflammation and pain offering relief for patients who have not responded to conservative treatments and wish to avoid or delay knee replacement surgery.
What are the Benefits of Genicular Artery Embolization (GAE)?
GAE offers several advantages over traditional surgical interventions for knee pain, including:
- Minimally invasive procedure with no large incisions
- Significant reduction in chronic knee pain and inflammation
- Performed as an outpatient procedure with no hospital stay required
- Faster recovery compared to knee replacement surgery
- Preserves the natural knee joint
- Safe option for patients who are not surgical candidates
- Avoid or reduce routine and regular repeated knee injections with this one time procedure
When is Genicular Artery Embolization (GAE) Recommended?
Dr. Malhotra may recommend GAE for patients who meet certain criteria, including:
- Chronic knee pain due to osteoarthritis
- Inadequate relief from physical therapy, medications, or steroid injections
- Desire to postpone or avoid total knee replacement surgery
- Patients who are poor surgical candidates due to age or other health conditions
What Does Preparation for Genicular Artery Embolization (GAE) Involve?
Prior to the procedure, patients will undergo a thorough evaluation including imaging studies such as X-rays or MRI to assess the knee joint. Blood tests may be ordered, and patients will be advised to avoid certain medications such as blood thinners. Arrangements for transportation home following the procedure should also be made in advance.
How is Genicular Artery Embolization (GAE) Performed?
GAE is performed under fluoroscopic or angiographic guidance. A small catheter is inserted through a tiny incision, typically in the wrist or groin, and guided to the genicular arteries surrounding the knee. Tiny embolic particles are then injected to block abnormal blood flow to the inflamed tissue, reducing pain and swelling. The procedure typically takes 30-45 minutes.
What to Expect During Recovery After Genicular Artery Embolization (GAE)?
Patients return home the same day. Mild soreness around the knee is common in the first few days. Significant pain relief is typically experienced within two to four weeks as inflammation subsides. Patients can gradually resume normal activities with guidance from Dr. Malhotra.
