What are the genicular nerves?

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.
