Overview

Peripheral nerve stimulation (PNS) is a drug-free pain management procedure that uses electrical impulses to target specific nerves and block pain signals. PNS helps decrease perception of pain, providing real answers to patients dealing with chronic knee pain. The case study discussed in this presentation is of the use of PNS targeting the superior lateral genicular nerve and the saphenous nerve for a patient with moderate to severe knee pain from osteoarthritis
