Purpose

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.

Active Comparator
Group 1 (Treatment)
Participants in Group 1 will have Leads placed by the nerves of the mid to upper thigh. These participants will then use the SPRINT Peripheral Nerve Stimulation (PNS) System and will receive electrical stimulation for 8 weeks.
  • 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).

Sham Comparator
Group 2 (Control)
Participants in Group 2 will have Leads placed by the nerves of the mid to upper thigh. These participants will then use the SPRINT Peripheral Nerve Stimulation (PNS) System and receive 8 weeks of sham stimulation. Participants will then have the option to crossover and receive stimulation therapy.
