Introduction: Total knee arthroplasty (TKA) volume may reach 3.5 million annually in the United States by 2030(1), yet 16–33% of patients develop chronic postoperative pain (CPOP), a figure higher after revisions(2). This pain undermines mobility, sleep, and prolongs opioid use. Conventional treatments—analgesics, physiotherapy, injections, genicular radio-frequency ablation-often fail. Percutaneous saphenous-nerve peripheral nerve stimulation (PNS) delivers reversible, opioid-sparing analgesia. We report an 80-year-old with refractory post-revision CPOP who achieved durable, medication-free relief after a 60-day PNS trial.
