Understanding Knee Osteoarthritis

At CardioVascular Health Clinic, your overall health matters to us. 

When you’re dealing with a debilitating condition such as osteoarthritis, our expert team of interventional radiologists can help.

Chronic knee osteoarthritis (OA) is one of the most common diseases of advanced age. With up to 20 million adults in the US suffering from OA of the knee, close to 700,000 cases progress to total knee joint replacement if left untreated.

However, there exists a large demographic of chronic joint pain patients who are not candidates for invasive procedures due to BMI, age, and other outside factors.

While many opt for alternative therapies such as arthroscopic debridement or injections, they are often associated with less-than-optimal clinical outcomes.​ Therefore, instead of these therapies, or even in conjunction with them, we recommend a noninvasive geniculate nerve ablation.

If you or a loved one has been diagnosed with knee osteoarthritis or are at risk of developing the condition, it is important to get evaluated and understand the best treatment options available for your unique situation and health goals.

Let’s discuss knee osteoarthritis in more detail, including what it is, common symptoms, and innovative knee osteoarthritis treatment options offered here. 

What Is Knee Osteoarthritis?

Knee osteoarthritis is the most common form of arthritis, a condition affecting the knee joints.

When knee osteoarthritis occurs, the cartilage protecting the ends of your knee bones wears away. This typically happens over several years, and symptoms progress if left untreated.

While knee osteoarthritis is the most common type, you can also experience osteoarthritis in the hips, hands, or spine. 

Once you develop severe knee osteoarthritis, you can suffer tremendous pain and loss of function, ultimately limiting your mobility and negatively impacting your overall health and physical activity level.

Knee Osteoarthritis Symptoms 

Knee osteoarthritis causes a wide range of symptoms that worsen over time.

Common symptoms include

  • Knee tenderness, especially when touched
  • Decreased range of motion and flexibility
  • Knee and leg stiffness, primarily upon waking or after periods of inactivity
  • Pain during or after movement
  • Swelling
  • Bone spurs on or around the affected knee joint
  • A grinding or grating sensation near the knee 

Risk Factors 

It is essential to understand that anyone can develop knee osteoarthritis.

Certain factors may increase your risk, including

  • Older age — your risk increases as you age
  • Gender — women are more likely to develop knee osteoarthritis
  • Obesity
  • Genetics
  • Bone deformities
  • Past knee trauma or injuries
  • Repetitive joint stress from knee overuse
  • Metabolic diseases, including diabetes and hemochromatosis

Noninvasive Knee Osteoarthritis Treatment 

Home remedies and medication regimes are not always effective for patients with chronic knee osteoarthritis or degenerative joint disease of the knee. 

In many cases, surgery may be the most effective. However, in cases where the patient is not a good surgical candidate (for example, due to age or the existence of two or more chronic conditions), there is another option to treat knee pain. 

The genicular nerve block and radiofrequency ablation (neurotomy) provide very effective therapeutic alternatives to surgery. The geniculate nerves are the nerves that sense pain in the knee.

The genicular nerve block and genicular radiofrequency ablation (RFA) can be done before or after knee surgery and may help patients avoid invasive surgery altogether.

The nerve block injects local anesthetic on the genicular nerve itself. This procedure tests the patient's response to determine if sufficient pain relief is experienced.

When the nerve block successfully provides substantial relief, this justifies a genicular nerve ablation or radiofrequency ablation, a longer-lasting pain relief option. 

The ablation procedure works on the theory that cutting the nerve supply to the knee may alleviate pain and restore function.

I’m about one month out and things are so much better. At my two week evaluation my symptom score had gone from a 27 to a 7, and I’m sure it’s even better now. That speaks volumes. Now that I’m post recovery, there is no incontinence, I go to the bathroom much less and there are no ED side effects like there are with other procedures. In regard to my quality of life, well, I don’t maintain my life based on my proximity to a bathroom anymore.

Professional staff working in a beautiful facility with great doctors who sincerely care about their patients. Without Dr. Schmidt's skill, I would have needed heart bypass surgery instead of a stent. Follow-up has been thorough. I can't recommend them highly enough.
LeAnn H.

Dr. Jim Melton and all the staff are fantastic. He is an excellent surgeon and his team is GREAT!!!! I just had surgery at the surgery center, I have only great things to say about my experience. Without him I really don't think I would be here to write this. If you’re looking for a good cardiovascular team, they are a 5 star for sure.

Susie H.

Dr. Parsons and staff are amazing. He truly listened to me from the consult. Staff showed genuine care for my progress post procedure. I had my follow up appointment today so satisfied with results. Blake made me comfortable from the start. He is an activist for uterine fibroids treatment beyond the standard.

Tamara M.

Professional and caring staff. Dr. Smith is very knowledgeable and shows genuine concern for your personal health. I enjoyed the background music in the procedure room, it really adds to the relaxing atmosphere.

David L.

Dr. John Schrader is the most personable doctor we know. He stays on top of my dads health care and is genuinely concerned about his health. We never leave his office with questions. He answers them all. Even questions we don’t think of. Always professional but never cold or bad bedside manner. In our opinion he is THE BEST around.
Thank you Dr Schrader.

I came to Dr. Warren by a self referral for mals when it took me 8yrs 50+ doctors and thousands of dollars spent on no answers. My first visit I was scared I was just going to be gaslighted just like the past however I was pleasantly shocked when Dr. Warren immediately believed me. She took the time to review many disk I had brought from past tests. She never once dismissed me and listened to ever word I had to say. She scheduled one last test to confirm the diagnosis then I was scheduled for surgery right away. Surgery was a success and I can’t thank her and her staff enough. Dr. Warren truly saved my life.

Angie W.

Dr. Garner literally saved my life 18 months ago and I've followed him to his new practice with Cardiovascular Health. He explains things so clearly, listens and is just a very nice person. His staff is great, too! I highly recommend!

Christy G.

The staff, the nurses, and Dr. Parsons were all amazing. Everything was simple and went well – very Bravo Zulu (military phrase meaning "well done"). In addition to the great staff at CardioVascular Health Clinic, the facilities were clean and well maintained. I have no complaints about anything. The whole experience was A1. I would recommend Dr. Parsons to anyone. He made a huge impact on my life.
