Is knee joint feeling nerve radiofrequency heat coagulation how one and the same?

Radiofrequency thermocoagulation is a very common method for chronic pain. By heating the nerve to make the nerve degeneration, achieve long-term block to relieve pain. This method is minimally invasive and does not require an operation. Guided by ultrasound or X-ray after local anesthesia, a very fine radiofrequency needle is punctured into the sensory nerve of the knee joint. The radiofrequency machine sends out an electric current to raise the temperature of the needle tip (5-10 mm) to 70℃-85℃ for several minutes. This method is accurate in positioning, and the heating range only reaches 5 mm around the tip of the needle at most. It is accurate in the nerve and has little effect on other parts. Reheating after local anesthesia does not cause severe pain.
