Radio Frequency Ablation (RFA), also known as neurotomy, uses radio frequency to generate heat that can ablate/destroy a small targeted are of nerve tissue to prevent it from carrying pain signals back to the brain. This commonly used in the neck, low back, and knees for painful arthritic conditions. It can be a long-term option for pain relief to decrease dysfunction and the need for pharmaceuticals. Commonly, the duration of pain relief can be six to twelve months, but some people experience years of relief. The treated nerve can regrow. When it happens, it is usually after about six months. RFA can be safely repeated if the pain returns.
