Clinical Trial Summary

The purpose of this study is to gather information about how knee pain changes when small amounts of electricity are delivered to the nerves in the leg. This study will involve the use of a Peripheral Nerve Stimulation (PNS) System that is made by SPR Therapeutics (the sponsor of the study). The SPRINT PNS System was cleared by the FDA for up to 60 days of use in the back and/or extremities for the management of acute and chronic pain.

Intervention

Device:
• SPRINT Peripheral Nerve Stimulation (PNS) System
The SPRINT System delivers mild electrical stimulation to nerves in the affected limb. The SPRINT System includes two small wires (called "Leads") that are placed through the skin in the upper leg. It also includes a device worn on the body that delivers stimulation (called the SPRINT Stimulator).
