AbstractKnee osteoarthritis, a chronic degenerative condition, can be a debilitating and limiting process with affected patients presenting with symptoms such as pain, restrictive range of motion, and swelling. This condition commonly afflicts millions of people with a higher incidence among the elderly that results from chronic mechanical repetitive loading. The treatment of pain generating conditions such as arthritis in large joints is complex requiring interventions of varying focuses such as weight loss, anti-inflammatory medications, corticosteroid, hyaluronic and viscosupplementation injections, and prescription opioids. A gap in the treatment options of this ailment currently exists between short term pain solutions and surgical approaches such as total knee arthroplasty that may offer longer pain relief. Cooled radiofrequency ablation is an emerging technique that offers a minimally invasive alternative for treating knee pain with a clinical relevance in patients who are not surgical candidates due to coexistent medical comorbidities or those who are undesiring of surgery. This procedure uses radiofrequency ablation that blocks genicular nerves from transmitting knee pain signals to the brain. Further research will allow the application of this technique to treat other sensory nerves in large joints such as the hip and shoulder.Copyright © 2020 Elsevier Inc. All rights reserved.
