Understanding Knee Osteoarthritis and How To Reduce Knee Pain

For years, knee osteoarthritis (OA) has been described as a “wear and tear” disease, suggesting that it’s an inevitable result of aging or overuse of our joints. However, modern research has revealed that this simplistic view is inaccurate and potentially harmful. The idea that our joints wear out like old car parts makes sense: use something enough, and it will eventually break down. This view has led many to believe that knee osteoarthritis is a natural part of aging or an unavoidable consequence of an active lifestyle.

Believing that OA is merely about worn-out joints can have several negative consequences:

  1. It may discourage people from staying active, fearing that exercise will accelerate joint damage.
  2. It can lead to a fatalistic attitude, making people less likely to seek early treatment or make lifestyle changes.
  3. It oversimplifies a complex condition, potentially leading to misunderstandings about prevention and treatment.

The Importance of Maintaining Joint Health

Understanding that OA is not just about wear and tear highlights the importance of proactive joint health management:

  1. Appropriate physical activity is beneficial, not harmful, for joint health.
  2. Maintaining a healthy weight reduces both mechanical stress and inflammatory factors.
  3. Early intervention and lifestyle modifications can significantly impact the course of the disease.

The Current Scientific Understanding of Knee Osteoarthritis

Modern research shows osteoarthritis is a complex, multifactorial disease involving various biological processes.

Inflammation

Contrary to popular belief, inflammation is a significant component of OA. While it’s not the same type of inflammation seen in rheumatoid arthritis, low-grade inflammation in the joint tissues contributes to its progression.

Joint Tissues

OA affects the entire joint, including:

  • Cartilage
  • Subchondral bone
  • Synovial membrane
  • Ligaments
  • Muscles surrounding the joint

Genetic Factors

Research has identified several genes associated with an increased risk of developing OA. This genetic component explains why some people develop OA despite leading healthy lifestyles, while others don’t, even with high-impact activities.

Metabolism

Metabolic health plays a role in OA. Conditions like obesity and diabetes can increase the risk of OA, not just through increased mechanical stress on joints but also through systemic metabolic effects.

Rather than simple “wearing out,” OA involves a complex interplay of repair and destructive processes in the joint. In OA, balance is disrupted, leading to progressive joint damage. The inflammation causes pain, stiffness, and reduced mobility. Your body releases excess inflammatory substances that irritate nerve endings, contributing to pain. These substances, known as inflammatory mediators, include cytokines, which signal inflammation, and prostaglandins, which amplify it.

GAE specifically targets these inflammatory processes, offering new hope to those suffering from knee OA.

How Genicular Artery Embolization Works

Targeting Abnormal Blood Vessels: In knee OA, abnormal blood vessels form in the lining of the joint. These vessels feed inflammation.

Precise Embolization: During Genicular Artery Embolization (GAE), our interventional radiologists guide a catheter to these abnormal vessels using advanced imaging, then inject tiny particles to block them.

Reducing Inflammation: By blocking these vessels, we reduce blood flow to inflamed areas, leading to decreased production of inflammatory mediators and, ultimately, less pain.

Think of GAE as turning down the volume on inflammation. It doesn’t eliminate it, but it significantly reduces the intensity of the pain.

GAE offers several key advantages for knee OA patients:

  • Minimally Invasive: No large incisions, meaning reduced scarring and faster recovery.
  • Quick Recovery: Most patients return to normal activities within days.
  • Long-Lasting Relief: Many patients experience significant pain reduction for months or even years.

As with any medical procedure, GAE carries some risks. However, the risks are minimal when performed by a skilled and experienced interventional radiologist. Commonly reported risks include mild bruising or soreness at the catheter insertion site. More serious risks, such as infection or damage to surrounding tissues, are rare and carefully managed by our team of experts.

Addressing Common Concerns

Is GAE right for me? 

GAE is recommended for patients with mild to moderate knee OA who haven’t found relief with treatments such as physical therapy or steroid injections.

Can I still have knee replacement surgery later? 

Yes, GAE doesn’t interfere with your ability to pursue knee replacement surgery if needed in the future.

How long does the procedure take? 

The entire GAE procedure typically takes about one hour.

Genicular Artery Embolization offers a revolutionary option for knee osteoarthritis patients, particularly those seeking a minimally invasive alternative to surgery. By targeting inflammation at its source, GAE provides long-lasting pain relief and improved joint function, helping you regain control of your life. Are you ready to take control of your knee pain?
