COOLIEF Cooled Radiofrequency Thermal Treatment


According to new article by, the FDA has cleared for marketing the COOLIEF Cooled Radiofrequency Thermal Treatment:

"The FDA has cleared for marketing the COOLIEF Cooled Radiofrequency (Cooled RF; Halyard Health) thermal treatment for the relief of chronic moderate to severe knee pain caused by osteoarthritis (OA). The first RF treatment to be cleared specifically to relieve OA knee pain, COOLIEF Cooled RF is a minimally invasive, thermal radiofrequency pain management system using water-cooled technology to deactivate pain-causing sensory nerves.

The clearance is based on results from a 151-patient, prospective, randomized multicenter study comparing COOLIEF Cooled RF with intra-articular steroid injections in patients suffering from knee pain due to OA. In 74.1% of the cooled RF patient group, pain was reduced by at least 50% at six months and maintained in over 65.4% of those patients for 12 months post-procedure. At baseline, 67.1% of the cooled RF group and 62.7% of the steroid injection group reported symptoms of severe OA. At six months post-procedure, only 5.2% of the cooled RF group reported the same severity level versus 37.3% of patients treated with steroid injections, as measured by the Oxford Knee Score, a validated outcomes instrument designed to assess function and pain associated with the knee. The cooled RF patient group’s Oxford Knee Score remained low for 12 months, with only 11.5% reporting severe symptoms at that point."
