New treatment instantly relieves knee pain

The iovera treatment uses a handheld device with nitrous oxide canisters to freeze short needle probes to negative 126 degrees. Once injected into the skin, the cold therapy kills away targeted sensory nerves around the knee-- which prevents the nerve from sending pain signals.

"Within 15 to 25 minutes we've frozen away the nerve and the patient will know immediately if they have good results," Chen said.

Chen says he typically sees people with arthritis or those who have had total knee replacements and still struggle with residual pain. The iovera treatment is cleared by the FDA, and is designed to provide temporary pain relief for up to six months after a single session.
