Introduction:

While total knee arthroplasty (TKA) is an effective surgical procedure, persistent postoperative pain can still impact up to 20% of patients. Percutaneous 60-Day Peripheral Nerve Stimulation (PNS) has been proven to reduce pain and improve function in patients with both persistent (chronic) and acute postoperative pain^1-4. The present analysis evaluated the efficacy of Percutaneous 60-Day PNS in relieving persistent postoperative pain and improving function following TKA up to 12 months after PNS treatment.
