Genicular Nerve Block (G Block)

This is an injection of anesthetic to the genicular nerves.  These are the sensory nerves that transmit pain signals from the knee to the brain.  Anesthetizing these nerves can disrupt the pain signal cause by degeneration of the knee.  A genicular nerve block can provide temporary pain relief.  It may help to determine if a patient is a candidate for nerve ablation or burning, which can provide long-term pain relief.
