Chronic knee pain can make even simple activities like walking, climbing stairs, or exercising feel difficult. For many patients, the cause is osteoarthritis, a condition that leads to inflammation, stiffness, and limited mobility. Osteoarthritis is the most common form of arthritis, affecting tens of millions of adults in the United States. When the cartilage that cushions the bones wears down over time, it causes friction, swelling, and inflammation. Common symptoms include pain or stiffness, especially after activity or rest, swelling or tenderness in the knee joint, difficulty walking, bending, or climbing stairs, and a grinding or catching sensation in the joint.
While medications, physical therapy, or injections can help manage symptoms, many patients continue to experience pain. Historically, when these conservative treatments failed, the next step was often a major surgical intervention. However, there is a growing demand for non surgical osteoarthritis treatments. Patients are actively seeking alternatives to major surgery that offer lasting relief without the extensive downtime. At Peak IR, our interventional radiologists offer genicular artery embolization in Spokane as a safe and effective, minimally invasive procedure to relieve pain and improve function for patients with knee osteoarthritis.
Genicular artery embolization, commonly referred to as GAE, is an innovative, image guided treatment for chronic knee pain. Using advanced imaging, GAE targets the tiny arteries that cause inflammation in the knee, providing lasting relief without surgery or long recovery times.
The procedure begins with a small puncture in the artery in the wrist or groin. Using advanced imaging, the interventional radiologist guides a thin catheter into the arteries that supply the inflamed areas of the knee. Tiny, medical grade particles are released into these arteries to block the abnormal blood flow causing inflammation. This reduces pain signals and helps decrease inflammation in the knee joint over time.
Clinical studies have demonstrated the effectiveness of this approach. A systematic review and meta analysis found that GAE is a safe procedure that confers significant improvement in knee osteoarthritis symptoms, with 78% of patients meeting the threshold for meaningful pain improvement at twelve months. The targeted embolization process blocks the abnormal blood flow that fuels the inflammatory cycle in the knee joint. The technical success rate across the studies was 99.7%, and adverse events were limited to minor occurrences such as temporary skin discoloration.

Significant surgical scar over the knee |
The recovery experience is one of the most significant differences between these two treatment pathways. Because GAE does not involve cutting bone or tissue, the healing process is remarkably swift.
Following a Genicular artery embolization, patients return home the same day. Most patients are back to normal activities within days. You can expect a noticeable decrease in knee pain within the first month after GAE, with results continuing to improve over time. The procedure does not require the extensive rehabilitation associated with joint replacement. You will be encouraged to walk and move normally shortly after the procedure, allowing you to quickly return to the activities you enjoy.
In contrast, recovering from a total knee replacement is a long and demanding process. According to the National Institutes of Health, most of the expected improvement in pain and function following a total knee replacement is achieved at six months, but some further improvement can be expected up to two years. The initial weeks involve significant pain management, limited mobility, and mandatory physical therapy to regain joint function. The surgical trauma requires the body to undergo a massive healing effort, which is why the rehabilitation phase is so critical and time consuming. While genicular artery embolization does not help repair the cartilage in your knee, its recovery is minimal and it can help significantly with knee pain. While a knee replacement is the only way to fix what is wrong in the knee, it comes at the price of an extensive surgery and long recovery.
Not every patient with knee pain is a candidate for the same treatment. GAE is typically best suited for patients who have moderate to severe knee osteoarthritis and have not found adequate relief from conservative treatments like physical therapy, anti inflammatory medications, or corticosteroid injections. It is also an option for patients who wish to delay or avoid a total knee replacement.
Patients with end stage osteoarthritis, where the cartilage is almost entirely gone and there is significant bone on bone contact, may still benefit more from a total knee replacement. The best way to determine the right treatment is through a thorough evaluation with a specialist. At Peak IR, our team will review your imaging, discuss your symptoms, and help you understand all of your treatment options so you can make an informed decision about your care.
Choosing the right path for managing knee osteoarthritis is a highly personal decision that depends on the severity of your condition, your overall health, and your lifestyle goals. While total knee replacement remains a highly effective option for end stage arthritis, it is not the only solution for chronic knee pain. Many patients find that they can significantly delay or entirely avoid surgery by exploring advanced interventional radiology techniques.
At Peak IR, our physicians combine advanced imaging technology with years of interventional experience. Every treatment is personalized to deliver safe, lasting results that improve comfort and mobility. We believe patients deserve lasting relief without invasive surgery or prolonged recovery. Our specialists use image guided procedures like genicular artery embolization to help restore comfort, mobility, and confidence so you can get back to the life you love.
If you are experiencing chronic knee pain and want to explore non surgical alternatives, we encourage you to schedule a consultation. Our team will thoroughly evaluate your condition, review your medical history, and discuss your symptoms to determine if you are a candidate for GAE or if another approach is better suited to your needs. We are committed to providing you with the information and care necessary to make the best decision for your joint health.
