Percutaneous denervation for the treatment of knee pain
摘要
Knee osteoarthritis is common and projected to increase in prevalence. When conservative treatments fail to improve pain and disability, the primary surgical option is total knee arthroplasty. Percutaneous image-guided ablation of the sensory articular nerve branches to the knee, also referred to as the genicular nerves, is a potential non-operative treatment. Here, we review the relevant anatomy, modes of denervation/neuromodulation, procedural techniques, and current controversies.
