What is genicular nerve block?

The nerve block is a term used for a procedure where the pain doctor injects anesthetics close to the nerve to block pain signals. A nerve block can both help to diagnose the specific origin of the pain and provide therapeutic relief. The knee joint receives nerves from articular branches of various nerves. Those nerve branches around the knee joint, also known as genicular nerves, can be easily approached through the skin under fluoroscopic guidance. Genicular nerve block is a non-surgical approach that prevents the nerves of the knee from sending pain signals to the brain. It is indicated in cases with chronic knee pain secondary to osteoarthritis, degenerative joint disease, failed knee replacement, and unfit for knee replacement. This safe and minimally invasive therapeutic procedure for chronic knee pain is usually conducted in two phases:

  • Diagnostic genicular nerve blocks
  • Radiofrequency neurotomy


The technique of genicular nerve block

Firstly, the pain doctor injects a small amount of local anesthetics around your genicular nerves. If the injection reduces the pain by 50% within 24 hours, then the pain doctor has hit the bull’s-eye. It’s now time for the next phase when your doctor applies cooled or conventional radiofrequency (a sophisticated type of radio wave) neurotomy to the nerves of your knee. In this procedure, a heat lesion is created around the nerves. Therefore, they are not able to carry the pain signals to the brain and you won’t feel pain for months. There may be a need for repeated injections. During the pain relief period, you can participate in physical therapy and improve your whole activity level.
