The role of peripheral nerve stimulation in refractory non-operative chronic knee osteoarthritis

Aim: This case series aimed to analyze the efficacy of a temporary peripheral nerve stimulation (PNS) device implanted for 60 days at 60 days post-explant for patients with non-surgical osteoarthritic knee pain. Patients & methods: 19 patients were selected for treatment with temporary PNS at an outpatient pain management clinic. Results: Patients demonstrated improvement in their knee pain from baseline post-temporary PNS explant (p = 0.973). Conclusion: Temporary PNS serves as a promising therapy for patients with limited options for therapy, necessitating further high-quality studies. Plain language summary Temporary peripheral nerve stimulation (PNS) is a treatment for patients with knee swelling and pain who can't get surgery. The authors studied temporary PNS to see if the patient's knee pain improved. 19 patients were treated with temporary PNS. The study found the patients' knee pain improved after completing the treatment. More research is needed in the future to temporary PNS in knee pain patients.
