Motor Sparing Techniques, Genicular Nerve Radiofrequency Ablation Has Emerged As a Viable Alternative to Conservative Therapy and Total Knee Arthroplasty

There has recently been considerable interest in the role of radiofrequency ablation (RFA) of the genicular nerves for KOA. In the majority of previous studies, ablation was done via a radiofrequency technique using either fluoroscopy or ultrasound for only three genicular nerves, whereas the knee joint is also supplied by a few other nerves (11, 12). Interestingly, neurolytic agents can also be used to ablate the nerves, and are readily available, less costly, and need less logistic support
