Where are the genicular nerve branches?
knee joint
The knee joint is innervated by the articular branches of various nerves, including the femoral, common peroneal, saphenous, tibial, and obturator nerves. These branches around the knee joint are known as genicular nerves.
What does the genicular nerve innervate?
Anatomy. saphenous, common peroneal, tibial and obterator nerves. Small, articular branches of these nerves, known as the genicular nerves, surround the knee and provide innervation to the joint.
How long does genicular nerve block last?

What is a genicular block?
What Is Genicular Nerve Block? 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.
What happens if a nerve block doesn’t wear off?

Where is the superior lateral genicular nerve located?
Superior lateral genicular nerve – accompanies artery of the same name and lies above the lateral femoral condyle. Inferior lateral genicular nerve – accompanies artery of the same name and lies just above the head of the fibula.
