What is intra-articular pulsed radiofrequency neuromodulation?
Pulsed Radiofrequency Neuromodulation is a needle-based, non-narcotic treatment that can be used for many purposes, one of which is chronic shoulder, knee, and other joint pain. Over time, inflammation in joints and ligaments is believed to cause small nerve endings to grow into the joint structures. These are not found in normal joints. These nerves can be treated using this advanced, minimally invasive, outpatient procedure, in which the physician directs the needle into the area of inflammation (the joint or other structure). Once the area is identified, pulsed electricity is used to create an electromagnetic field at the tip of the needle. This electromagnetic field is thought to change the balance between inflammatory (pain-causing) and inhibitory (pain-relieving) factors in the immediate area to reduce pain.
Studies have shown that Pulsed Radiofrequency Neuromodulation reduced joint pain by 50-70% for up to 1 year, which was associated with increased function and better quality of life.
