Summary

This trial uses the SPRINT PNS System, a device that sends electrical signals to nerves, to help patients with knee pain after knee replacement surgery. The device aims to reduce pain by targeting specific nerves with electrical pulses. If needed, additional signals can be added for better pain relief. The SPRINT PNS System has been used to manage chronic postoperative knee pain by targeting specific nerves with electrical pulses.

Experimental Treatment

Group I: SPRINT® Peripheral Nerve Stimulation (PNS) SystemExperimental Treatment1 Intervention

SPRINT PNS System will be offered to patients with postoperative knee pain following primary unilateral total knee arthroplasty (TKA) who meet eligibility criteria and consistent with established coverage policy. SPRINT PNS System will be implanted for 60 days. At the discretion of the physician, the first lead may be placed to stimulate the nerve innervating the region of greatest pain. If pain is not adequately addressed by the first lead when assessed at 10 days, a second lead may be placed approximately 2 weeks following the initial lead placement.
