What is Chronic Knee Pain? 

If you have been experiencing pain in your knee for two to three months without an adequate explanation, you have chronic knee pain. Chronic knee pain can be caused by injuries, mechanical problems, types of arthritis, and (much less likely) tumors. Chronic knee pain can affect a person of any age. 

Am I at risk?

A number of factors can increase your risk of having chronic knee pain, including: 

  • Being overweight or obese
  • Lack of muscle flexibility or strength
  • Certain sports or occupations that require repetitive stress on the knees
  • A past injury of the knee
  • Age
  • Osteoarthritis
  • Gout
  • Disease

What are the symptoms?

Depending on the cause of problem, the location and severity of pain may vary. However, common symptoms that accompany chronic knee pain include: 

  • Swelling and stiffness 
  • Popping or crunching noises 
  • Weakness or instability 
  • Inability to fully straighten the knee 
  • Redness and warmth to the touch 

What is COOLIEF™? 

COOLIEF™ or Cooled Radiofrequency is a minimally invasive treatment option targeting nerves that transmit pain signals and the first and only radiofrequency treatment FDA-cleared for the relief of osteoarthritis knee pain. 

Is genicular nerve ablation (COOLIEF) right for me? 

Genicular nerve ablation is an excellent option to bring non-surgical relief to those suffering from chronic pain, without the use of opioid medication. So, if you are not ready for surgery, or you don’t like the potential side effects of opioids, then ask your interventional radiologist about COOLIEF.   

In studies of patients who specifically had a COOLIEF treatment one year ago, two-thirds say that their pain level has been cut in half, compared to those who chose intra-articular steroid injections. Eighty-three percent of patients who had been suffering from severe arthritis also report a reduction in pain with COOLIEF.  

COOLIEF is often a good option for people with moderate to severe osteoarthritis pain who are not ready to have knee replacement surgery, or who have health conditions that don't make them a good candidate for surgery.
