Knee ablation, technically known as genicular nerve ablation, is a minimally invasive procedure aimed at treating chronic knee pain. The process involves using either heat (radiofrequency ablation) or cold (cryoablation) to disrupt the genicular nerves around the knee, which are responsible for transmitting pain signals to the brain. By ablating or 'turning off' these nerves, the procedure can effectively reduce or even eliminate knee pain. This treatment is especially beneficial for individuals who have not responded to conservative pain management methods or are not candidates for knee replacement surgery.
