GAE is a one-hour percutaneous procedure designed to relieve knee pain for 2-3 years. It is performed using a catheter and a tiny
1.3 mm needle.

After the procedure, you will leave with just a band-aid and can resume normal activities within a couple of hours.

Genicular Artery Embolization is:

  • Safe 
  • No Incision
  • Minimal Pain
  • No Scaring
  • No General Anesthesia
  • Outpatient Procedure
  • Two Hour Recovery Time
  • Go Home The Same Day 
  • Cost Less 

Knee pain can have many symptoms, including:

  • Swelling
  • Stiffness
  • Redness and warmth
  • Weakness or instability
  • Popping or crunching noises
  • Inability to fully straighten the knee
  • Locking or catching
Treatment Option:
Genicular artery embolization (GAE) is a minimally invasive procedure used primarily to treat chronic knee pain, often associated with osteoarthritis.

Several reasons why someone might choose GAE over other treatment options:
1. Minimally Invasive
  • Procedure: GAE is performed through a small puncture in the skin, typically in the groin area, using a catheter to navigate to the genicular arteries.
  • Recovery: It generally involves less recovery time compared to surgical options such as knee replacement.
2. Pain Relief
  • Effectiveness: Studies have shown that GAE can significantly reduce pain associated with osteoarthritis. The embolization blocks the blood supply to the inflamed synovium, reducing inflammation and pain.
3. Alternative to Surgery
  • Non-surgical Option: For patients who are not ideal candidates for surgery due to age, comorbidities, or personal preference, GAE offers a viable alternative.
  • Delay or Avoid Surgery: It can be an option for those looking to delay or avoid knee replacement surgery.
4. Shorter Recovery Time
  • Quick Return to Activities: Most patients can return to normal activities within a few days, compared to weeks or months of recovery after knee surgery.
  • Outpatient Procedure: Typically performed on an outpatient basis, meaning patients can go home the same day.
5. Lower Risk of Complications
  • Fewer Complications: Compared to surgery, GAE generally has a lower risk of complications such as infection, blood clots, and prolonged pain.
6. Symptomatic Relief
  • Targeted Treatment: The procedure targets specific arteries supplying the knee joint, which can result in localized and effective pain relief.
  • Reduced Inflammation: By reducing blood flow to the inflamed areas, GAE helps in decreasing overall knee inflammation and related symptoms.
7. Preserving Joint Function
  • No Joint Replacement: Since GAE doesn’t involve replacing the knee joint, it preserves the natural joint structure and function.
  • Mobility Maintenance: Patients often maintain better mobility and knee function compared to those undergoing more invasive procedures.
8. Repeatable Procedure
  • Repeatability: If necessary, GAE can be repeated to manage symptoms over time, offering continued relief without the need for major surgery.
9. Suitable for a Wide Range of Patients
  • Broad Applicability: GAE is suitable for a wide range of patients, including those with comorbid conditions that might make other procedures risky.
Procedure Overview:

Our medical team in San Jose performs Genicular Artery Embolization, led by our specialized Interventional Radiologists (IR). With advanced imaging, a thin catheter is guided to the knee arteries, where minuscule particles are used to reduce inflammation and provide long-lasting relief from discomfort. This procedure offers an alternative to surgery, with patients returning home the same day and experiencing pain relief within two weeks.

Pre-Procedure Preparation:

Patients should avoid NSAIDs like ibuprofen for five days before treatment, consulting their doctor first. Quitting smoking is recommended to enhance healing and treatment effectiveness.

Post-Procedure Care:

Patients may have mild discomfort or swelling afterward. Using Tylenol and ice packs can help manage this. Patients can resume daily activities at their discretion and contact us for further guidance.
