Osteoarthritis of the knee is the most common cause of chronic, persistent pain that can significantly impact your quality of life. If you’ve tried medications, physical therapy, or other interventions without success, Genicular Artery Embolization may offer the relief you seek. GAE is a minimally invasive procedure that targets the blood vessels causing inflammation and pain, providing a promising alternative to major surgery.
What is GAE?
Genicular Artery Embolization (GAE) is an innovative treatment designed to alleviate knee pain caused by osteoarthritis. The procedure focuses on the blood vessels within the knee that contribute to inflammation. By blocking these vessels, GAE reduces inflammation and pain, offering relief to patients who haven’t found success with other treatments.
Dr. Aaron Kovaleski, a leading expert in the field, describes GAE as a procedure that “effectively targets the inflamed blood vessels, providing significant pain relief with minimal recovery time.”
How Does GAE Work?
The GAE procedure involves injecting tiny particles into the genicular arteries to block blood flow, thus reducing inflammation and pain. Dr. Kovaleski explains, “During the procedure, we use advanced imaging techniques to guide a small catheter into the knee’s blood vessels. Once in place, we release microscopic particles that obstruct the blood flow to the affected areas, which diminishes the inflammation and alleviates pain.”
Who is a Candidate for GAE?
Candidates for GAE typically include those with moderate to severe knee osteoarthritis who have not found relief from other treatments like medications, physical therapy, or injections. Ideal candidates are those seeking a minimally invasive solution to manage their pain without undergoing major surgery.
Preparing for GAE: What to Expect
Before undergoing GAE, patients will have pre-procedure consultations and imaging studies to map out the blood vessels in the knee. Dr. Kovaleski notes, “It’s important to have a detailed understanding of the knee’s vascular structure to ensure the procedure’s success.“
On the day of the procedure, patients may be asked to fast for a few hours. The procedure is performed under moderate sedation and local anesthesia, allowing patients to sleep during the procedure without the need for advanced airways as with general anesthesia.
The GAE Procedure: Step-by-Step
The GAE procedure is typically completed within one to two hours. Here’s a step-by-step overview:
- Moderate Sedation: The procedure begins with administering moderate sedation, sometimes referred to as “conscious” sedation, through an IV to allow the patient to sleep comfortably during the procedure.
- Local Anesthesia: Next, local anesthesia is administered to numb the area around the knee.
- Catheter Insertion: A tiny catheter is inserted through a small incision near the knee and guided to the problematic (inflamed) blood vessels.
- Particle Injection: Using imaging guidance, microscopic particles are injected into the genicular arteries to block blood flow, reducing inflammation and pain.

Post-Procedure Care
After the procedure, patients are monitored for a short period before going home. Some bruising and soreness at the catheter site are common, but these symptoms usually resolve within a few days. Patients are advised to avoid strenuous activities for the first few days post-procedure.
Potential Risks and Complications
Like any medical procedure, GAE carries some risks. Common side effects include bruising and mild pain at the catheter site. Rare complications may include infection or blood clots. However, GAE has a strong safety profile with low complication rates.
Benefits of GAE
GAE offers several benefits, making it an attractive option for managing knee osteoarthritis:
- Pain Relief: Many patients experience significant pain relief within weeks of the procedure.
- Improved Knee Function: Increased mobility and reduced stiffness are common outcomes.
- Minimally Invasive: GAE is a minimally invasive alternative to knee surgery, with quicker recovery times and fewer risks.
Success Rates and Patient Outcomes
Numerous clinical studies have demonstrated the effectiveness of GAE. For instance, a study published in the CardioVascular and Interventional Radiology Journal reported that patients experienced durable pain relief and functional improvement following GAE.
Another study by Stanford Medicine highlighted a high technical success rate and significant pain reduction in patients with knee osteoarthritis.
FAQs and Answers
“Is GAE a permanent solution?”
GAE can provide long-term relief, with most patients reporting a 50-70% reduction to their pain, but it may not be a permanent cure. Some patients may require repeat procedures over time or, in severe cases, surgical intervention.
“What is the recovery time?”
Most patients can return to normal activities within a week, with significant pain relief observed within 1-3 weeks post-procedure.
“How safe is the GAE procedure?”
GAE is considered very safe with a low complication rate. Common side effects include mild bruising and pain at the catheter site, while rare complications may include infection or blood clots (Stanford Medicine).
“How does GAE compare to traditional knee surgery?”
GAE is minimally invasive, requiring only a small incision and local anesthesia, whereas traditional knee surgery involves more extensive incisions, general anesthesia, and longer recovery times. Patients undergoing GAE typically experience fewer risks and quicker recovery.
“What kind of follow-up care is required after GAE? “
Follow-up care is minimal. Patients are usually monitored for a short period immediately after the procedure and can go home the same day. It is recommended to avoid strenuous activities for the first few days, but most can return to normal routines within a week. Regular follow-up appointments may be scheduled to monitor progress and ensure the procedure’s success.
