Knee Arthritis Treatment

Seeking treatment for chronic knee pain is essential not only for immediate pain relief but also for preventing long-term complications. By addressing the underlying causes of knee pain, individuals can regain their independence, improve their functionality, and return to the activities they enjoy.

Genicular artery embolization for knee pain

Minimally invasive treatment for chronic knee pain

Ongoing knee pain can interfere with everyday activities like walking, climbing stairs, or standing from a seated position. When pain persists, it often reduces mobility and activity levels, which can negatively affect overall health and quality of life. Left untreated, chronic knee pain may lead to decreased strength, joint instability, and a greater likelihood of injury. Seeking treatment early can help reduce symptoms, improve function, and support a more active lifestyle.

Understanding knee osteoarthritis

Knee osteoarthritis occurs when the protective cartilage that cushions the ends of bones gradually deteriorates. Cartilage normally allows the joint to move smoothly and absorb impact during movement. As it breaks down, the bones in the knee may begin to rub together, which can lead to pain, stiffness, inflammation, and limited movement.

While osteoarthritis is often associated with aging, other factors such as prior injuries, excess body weight, or genetics can also contribute to its development. Knees are among the joints most commonly affected by this condition.

What Is Genicular Artery Embolization (GAE)?

Genicular Artery Embolization (GAE) is a minimally invasive procedure used to help relieve chronic knee pain, particularly when osteoarthritis is the cause. It is performed by an interventional radiologist who uses advanced imaging to guide specialized instruments through the blood vessels. Because the technique does not require large incisions, patients typically return home the same day. GAE is designed to reduce inflammation in the knee joint and provide relief for patients who have not found success with medications, injections, or other conservative treatments.

Interventional radiology can be used to treat a variety of urologic and urogynecologic conditions. Learn more about other procedures.

How the procedure works

GAE is typically performed in an outpatient setting using local numbing medication and light sedation. During the procedure, a physician inserts a small catheter into an artery and navigates it toward the arteries that supply blood to the inflamed lining of the knee.

Once these vessels are identified, microscopic particles are delivered through the catheter to partially block the abnormal blood flow contributing to inflammation. By decreasing circulation to these inflamed tissues, the procedure helps reduce swelling and pain within the joint

Benefits of GAE

Many patients choose genicular artery embolization because it offers several advantages compared to traditional surgery:

Minimally invasive outpatient procedure

  • No hospital stay required
  • Uses local anesthesia instead of general anesthesia
  • Short recovery time with a quick return to daily activities
  • Helps decrease inflammation and knee pain
  • May delay or help patients avoid knee replacement surgery

What results can patients expect?

Relief from knee pain varies from patient to patient, but many individuals experience noticeable improvement for several months to multiple years after treatment.

GAE does not cure osteoarthritis, but it can significantly reduce inflammation and discomfort while helping patients maintain mobility and independence. In some cases, the procedure can be repeated if symptoms return.

Non-surgical knee pain relief

For patients living with knee osteoarthritis, genicular artery embolization offers a non-surgical approach to reducing pain and restoring function. By targeting the blood vessels associated with inflammation, this treatment focuses on addressing the underlying cause of discomfort rather than simply masking symptoms. Many patients find that GAE helps them return to the activities they enjoy while avoiding more invasive procedures.
