COOLIEF® Knee Cooled Radiofrequency

According to the CDC, over 30 million adults in the US suffer from chronic knee osteoarthritis (OA). (1) The condition becomes more prevalent with age. Each year, approximately 700,000 total knee replacements are performed in the US. (2)

However, many patients who suffer from chronic joint pain are not good candidates for surgery due to age, heart problems, obesity, and known adverse reactions to anesthesia. In addition, alternative treatments, such as arthroscopic debridement or joint injections, are often ineffective.

If you’re looking for an effective non-surgical alternative to joint replacement surgery, ask us about COOLIEF® cooled radiofrequency. This minimally invasive treatment option uses cooled radiofrequency energy to safely treat chronic arthritis knee pain. COOLIEF targets the nerves that are causing pain. In clinical studies, cooled RF has been shown to provide over 24 months of pain relief and improved mobility in patients with other sources of pain. (3,4)


  • Non-surgical, minimally invasive outpatient procedure
  • Improved physical function and mobility
  • Decreased pain and disability
  • No narcotic pain medicine necessary

How Does COOLIEF Work?

COOLIEF is a minimally invasive outpatient procedure and requires no incision or general anesthesia. After the doctor numbs your knee, he will place several needles into your knee where the sensory (genicular) nerves are. He then uses a thin probe to deliver the radiofrequency energy through the needles. The radiofrequency heats the nerves and destroys them, decreasing your pain.

The length of the procedure will vary depending on how many nerves are treated, but it typically takes less than 3 minutes to treat each individual nerve. You may experience some temporary discomfort, but it can be managed with over-the-counter pain relievers – no narcotics necessary.

Most patients can return to work and routine daily activities within several days, and you should begin to experience pain relief within one to two weeks.
