Patients will be asked to take part in this research study because they have mild-to-moderate knee osteoarthritis (OA) and were referred clinically for a procedure called Genicular Artery Embolization (GAE). Osteoarthritis is the most common form of arthritis. It occurs when the protective cartilage that cushions the ends of the bones wears down over time. The symptoms of OA include pain or aching, stiffness, decreased range of motion, and swelling. The purpose of this study is to evaluate the safety and effectiveness of GAE for the treatment of knee pain attributed to OA.
Research participants will be in this research study for about 3 years. The study includes a screening visit, GAE procedure, and six follow-up visits.
At the screening visit, a review of their medical history, demographics, and medications will be collected; physical examination will be completed; knee x-ray will be done; and two questionnaires on your knee pain will be administered. The GAE procedure will involve receiving sedation or medication to help them relax, lidocaine injected under the skin in the area of the body where catheters will be inserted into one of your arteries and then using x-ray, a catheter will be directed to the arteries supplying the lining of the knee. Then tiny microspheres will be injected into the artery to decrease the blood supply to this knee joint tissue.
The follow-up visits up to 12 months will include a focused physical examination of the treated knee, documentation of medications, and two questionnaires will be administered. The follow-up visits at year 2 and 3 will include documentation of medications and any new treatments for OA as well as completion of two questionnaires. Follow-up visits maybe conducted in clinic or remotely.

Experimental: GAE Procedure
All participants will undergo a procedure called Genicular Artery Embolization (GAE) that will be done to try to reduce the pain in their knees.
|
Genicular Artery Embolization is performed by either inserting a small catheter into the artery of the upper thigh or an artery at the wrist, and with the use of x-ray, the catheter is guided to the arteries supplying the lining of the knee.
Tiny particles are then injected through the catheter into these arteries, reducing the blood supply.
These small particles are considered a medical device called Embosphere Microspheres.
These microspheres are approved by the Food and Drug Administration (FDA) in the United States to treat hypervascular tumors; in the prostate arteries to relieve symptoms related to benign prostate hyperplasia; and to address arteriovenous malformations.
The use of Embosphere Microspheres in this study is considered experimental as it has not been approved by the FDA to reduce pain associated with knee OA.

Patient safety endpoints
Zeitfenster: Screening/baseline, 1, 3, and 6 months
|
Primary safety endpoints include: 1. Incidence and severity of adverse events (AEs). These include:
|
Screening/baseline, 1, 3, and 6 months
|
|
Objective clinical endpoints - Cone beam computed tomography
Zeitfenster: Immediately pre-and post-embolization
|
Change in enhancement on cone beam computed tomography (CT)
|

|
Objective clinical endpoints - VAS
Zeitfenster: Screening/baseline, 1, 3, 6, 12, 24 and 36 months
|
Change in Visual Analogue Scale (VAS), a measurement instrument where 0 represents the minimum value (e.g., no pain) and 100 (or 10) represents the maximum value (e.g., worst imaginable pain).
Consequently, higher scores indicate a worse outcome (more pain/severity), while lower scores indicate a better outcome

Screening/baseline, 1, 3, 6, 12, 24 and 36 months

|
Objective clinical endpoints - WOMAC
Zeitfenster: Screening/baseline, 1, 3, 6, 12, 24 and 36 months
|
Change in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), a measurement instrument designed to evaluate pain, stiffness, and physical function in patients with hip or knee osteoarthritis.
Higher scores on the WOMAC indicate a worse outcome (greater pain, stiffness, and functional limitations).
