The tear of the tissue at the end of knee bone is a type of degenerative joint disease known as OA osteoarthritis. It is majorly found in the old age population. As per the survey and analysis, there are approximately 20 Million adults in the US itself suffering from OA majorly in the knee, and about 700,000 cases advance to the total knee joint replacement. There are also some of the patients who are suffering from chronic joint pain but cannot go through the invasive treatment owing to age, BMI, and other physical factors that depend on the response of the body. There are alternative therapies such as infusions or arthroscopic debridement but their clinical results aren’t that ideal.
Georgia-based company Halyard health received a grant for Its COOLIEF Cooled Radiofrequency technology that is intended to treat the chronic knee pain due to osteoarthritis. This technology will be more beneficial for the patients who can’t afford the knee replacements and for those who prefer to wait for whatever reason. The technology developed by Halyard Health is the only RF based technique that has managed to clear the FDA approval procedures specifically for pain relief in knees. The company claims that the technique would definitely assist the patients to evade the steroid injection, drugs that also have their own side effects and chances of addiction.
COOLEIF Cooled is a non-narcotic, minimally invasive, and non-surgical solution for genicular neurotomy. As it will be treated in an outpatient form, a patient can readily return to normal life as well as reduces the narcotics usage too.
How is it done?
The COOLIFE distributes RF energy on the focused nerves while using cold water to cool the adjacent area. This helps to deactivate the nerves without damaging the nearby tissues.
The clearance that was approved by the FDA came after the results from 151-pateints. The study involved two types of cases; one, the patients treated with Cooled RF and second, the patients injected with intra-articular steroid injections suffering from a knee pain due to osteoarthritis. In the group of 74% of cooled RF patient, it was seen that only 5.2% of the cooled RF group reported severity level against the 37.3% of patients that were treated with steroid injections after 6 months of treatment.
