If you’re living with chronic knee pain, the number one mistake that makes knees worse is relying on temporary pain relief, such as repeated cortisone shots, while ignoring the chronic inflammation that continues damaging the joint underneath. Pain may disappear for a while, but the disease process often continues silently.

Many people believe that if their knee feels better, it must be getting better. Unfortunately, that’s not always true. In knee osteoarthritis, pain relief doesn’t necessarily mean the joint is healing. In many cases, inflammation continues breaking down cartilage even when symptoms temporarily improve.

At Precision Vascular Kentucky, we help patients understand the difference between simply masking pain and treating one of its underlying biological drivers. For many people with mild to moderate knee osteoarthritis, Genicular Artery Embolization (GAE) offers a minimally invasive alternative focused on reducing chronic inflammation rather than simply covering it up.

The Cycle of Temporary Knee Relief

It usually starts the same way.

Your knee begins aching after walking, climbing stairs, or exercising. The discomfort gradually becomes harder to ignore, so you receive a cortisone injection. Within days, the pain fades, and life feels normal again. You become more active, return to your favorite routines, and stop thinking about your knee.

Several months later, however, the pain returns. This time it often feels worse. Another injection brings temporary relief, but eventually each treatment seems to last for a shorter period.

Many people unknowingly spend years repeating this cycle.

The problem isn’t that cortisone injections are ineffective. They can provide meaningful short-term relief for many patients, especially during painful flare-ups. The real issue arises when temporary symptom control becomes the only treatment strategy while chronic inflammation continues damaging the joint.

Think of knee pain like the warning light on your car’s dashboard. Covering the warning light doesn’t fix the engine problem. Likewise, eliminating pain without addressing ongoing inflammation doesn’t stop osteoarthritis from progressing.

How Cortisone Can Mask the Real Problem

Corticosteroids are powerful anti-inflammatory medications. By reducing inflammation quickly, they often provide significant pain relief and improve mobility for weeks or months.

The challenge is that once pain disappears, many patients naturally return to activities that place stress on an already vulnerable joint. Since the underlying cartilage has not been restored, mechanical wear continues while the protective warning signal, pain is temporarily muted.

Research has also raised concerns about repeated corticosteroid injections over long periods. Some clinical studies suggest that frequent injections may be associated with increased cartilage volume loss in certain patients, particularly when used repeatedly over several years. This doesn’t mean cortisone should never be used, but it does highlight why many specialists recommend using it thoughtfully rather than as an indefinite long-term solution.

For patients with chronic knee osteoarthritis, simply repeating injections every few months may not address the disease process that continues beneath the surface.

The Hidden Enemy: Chronic Synovitis

One of the biggest drivers of osteoarthritis progression is synovitis, or chronic inflammation of the knee’s synovial lining.

The synovium normally produces lubricating fluid that allows the knee to move smoothly. During osteoarthritis, however, this tissue can become chronically inflamed.

When synovitis persists, inflammatory chemicals, including cytokines and destructive enzymes, are released into the joint. These substances gradually break down cartilage, irritate surrounding tissues, and contribute to ongoing pain.

Unlike soreness after exercise, chronic synovitis doesn’t simply resolve with rest. It creates a persistent inflammatory environment that accelerates joint degeneration over time.

This is why many patients experience increasing stiffness, swelling, and discomfort even when X-rays show only moderate arthritis.

What Happens Inside an Arthritic Knee?

As inflammation continues, the body attempts to repair the damaged joint. Ironically, this healing response can contribute to even more pain.

One important biological process is called neovascularization, which refers to the growth of abnormal new blood vessels within the inflamed tissues surrounding the knee.

While new blood vessels often help heal injuries elsewhere in the body, these vessels behave differently in chronic osteoarthritis. Instead of resolving inflammation, they help sustain it.

Even more importantly, these abnormal vessels often grow alongside new sensory nerve fibers. These hypersensitive nerves make the joint far more responsive to movement, pressure, and inflammation.

The result is a cycle that feeds itself:

• Chronic inflammation stimulates abnormal blood vessel growth.
• Those blood vessels support new pain-sensitive nerves.
• Pain and inflammation continue reinforcing one another.
• Cartilage gradually wears away.
• The knee moves closer to advanced “bone-on-bone” arthritis.

This biological process helps explain why knee pain often worsens even when patients are trying their best to stay active.

Why Treating the Root Cause Matters

Rather than simply asking, “How can we reduce today’s pain?” many physicians now ask a different question:

“How can we reduce the chronic inflammation driving the pain?”

This shift in thinking has led to newer treatment options designed to intervene earlier in the disease process before patients require total knee replacement.

For patients who aren’t ready for surgery, or who want to delay it whenever possible, addressing chronic inflammation may help preserve mobility and improve quality of life.

Genicular Artery Embolization (GAE): A Different Approach

At Precision Vascular Kentucky, one of the most promising minimally invasive treatments for knee osteoarthritis is Genicular Artery Embolization (GAE).

GAE is an outpatient procedure performed by an experienced interventional radiologist using advanced image guidance. Instead of making large surgical incisions, the physician accesses the blood vessels through a tiny catheter inserted into an artery.

Using real-time imaging, the physician identifies the abnormal arteries supplying the chronically inflamed tissues inside the knee.

Tiny microscopic particles are then carefully delivered into these overactive blood vessels. By reducing excessive blood flow to the inflamed synovium, GAE helps decrease the inflammatory process and quiet the hypersensitive nerve endings associated with chronic osteoarthritis pain.

Rather than simply masking discomfort, GAE targets one of the biological mechanisms responsible for ongoing inflammation.

Benefits of GAE for Mild to Moderate Knee Osteoarthritis

For carefully selected patients, Genicular Artery Embolization offers several important advantages.

Unlike traditional surgery, GAE requires no large incision, no joint replacement, and is typically performed as an outpatient procedure. Most patients return home the same day without the prolonged recovery associated with major orthopedic surgery.

Because the procedure focuses on reducing chronic inflammation, many patients experience meaningful improvements in pain and function while preserving their natural knee joint.

GAE may be particularly beneficial for patients with Stage 1 through Stage 3 knee osteoarthritis who continue experiencing pain despite medications, physical therapy, activity modification, or injections.
