Genicular Nerve Blocks

Genicular nerve blocks are used to treat chronic knee pain. There are three nerves that innervate the knee: the superior medial genicular nerve, superior lateral genicular nerve and inferior medial genicular nerve. These are all reached very easily with a needle placement under x-ray guidance. After we have blocked the nerve successfully and determined that the patient has more than 50 to 60% reduction in their pain, we are able to consider a radiofrequency ablation of the same nerves utilizing another technique known as Coolief, or cooled radiofrequency thermocoagulation.
