The FDA has given the green light to a new treatment that will ease the pain of knee arthritis for people who can't have surgery.
Newly approved 'Coolief' is a non-invasive procedure that uses radio frequency to freeze nerve cells to stop them from transmitting pain signals to the brain.
Although it doesn't cure osteoarthritis, it offers an alternative treatment to patients who can't have a knee replacement surgery.
The new technique can alleviate the debilitating pain for up to a year, an improvement from steroid injections which normally last up to 12 weeks.
