BACKGROUND: Osteoarthritic knee (OAk) pain is common, yet the standard of care often yields unsatisfactory pain relief. There remains a role for novel treatment options. Percutaneous motor peripheral nerve stimulation (mPNS) of the knee is a novel minimally invasive procedure that stimulates motor end points leading to muscle contraction associated with the painful joint. Pain relief is hypothesized to be achieved through central pain modulation.CASE REPORT: We report the case of a patient who experienced refractory osteoarthritic knee pain after 9 months of conservative care. Following 7 weeks of mPNS treatment, the patient achieved improvement in OAk pain relief and activities of daily living as measured by notable improvements in the Brief Pain Inventory-Short Form and Knee Injury and Osteoarthritis Outcome Score at 8- and 12-weeks postimplant. The Patient Global Impression of Change at the end of stimulation was much improved.CONCLUSION: Motor PNS may offer a safe and effective treatment alternative for chronic refractory pain related to OAk.KEY WORDS: Osteoarthritis, knee, pain, peripheral nerve stimulation
