What Is Genicular Nerve (KNEE PAIN) Block & Destruction?
The word “genicular” refers to the various arteries (femoral and popliteal) and nerves that feed into the knee. For people with knee osteoarthritis, the pain signals delivered by these nerves can become unbearable.
A genicular nerve block temporarily blocks the nerve signals in the knee. During the GNB procedure, your doctor will target the superior medial, the superior lateral and the interior medial nerves of your knee with anesthesia. The anesthesia numbs the nerves and prevents them from sending a pain signal to the brain.
If the nerve block works we may suggest injecting another destructive agent such as 10% saline, or ethyl alcohol to damage the nerve for a longer period of time.
It is important to note that peripheral nerves do eventually grow back and the procedures might need to be repeated.
Are There Risks Associated With Genicular Nerve Block?
GNB is a non-surgical procedure that carries few risks. However, some cases of adverse side effects have been reported. These side effects include pain, redness or swelling at the injection site, nausea and dizziness.
