GENICULAR NERVE BLOCK PROCEDURE

WHAT IS A GENICULAR NERVE BLOCK?

A genicular nerve block is a minimally invasive outpatient procedure. It involves the injection of an anesthetic to the genicular nerves. Anesthetizing these nerves disrupts the transmission of pain signals from knee degeneration, providing temporary relief. Moreover, healthcare professionals use this procedure as a diagnostic tool to determine if the patient is a suitable candidate for genicular nerve ablation, which can offer long-term pain management.

WHAT ARE GENICULAR NERVES?

Genicular nerves are the sensory nerves responsible for transmitting pain signals from the knee to the brain. These nerves form a complex network around the knee joint and play a pivotal role in our perception of knee pain. Understanding the anatomy and function of the genicular nerves enables healthcare professionals to better assess and address knee-related conditions, allowing for more targeted treatment approaches.

HOW IS THE PROCEDURE PERFORMED?

To prepare for the procedure, the healthcare professional thoroughly cleanses and sanitizes the skin of the knee. Additionally, a local anesthetic is administered to numb the injection sites, ensuring patient comfort. With the aid of a fluoroscope, a specialized x-ray device that provides real-time images, the physician precisely guides a needle to one of the targeted genicular nerves. Subsequently, an anesthetic mixture is then injected through the needle, effectively numbing the nerve and providing immediate pain relief.

The physician repeats the injection process at two additional locations to anesthetize a total of three genicular nerves. Once the procedure is complete, the injection sites are carefully bandaged, and the patient is permitted to return home. After the nerve block, the patient should be able to walk normally and experience a significant reduction in pain symptoms.
