Knee osteoarthritis is one of the leading causes of disability and pain in the world. Genicular nerve radiofrequency ablation (RFA) is an effective interventional procedure for chronic knee pain due to knee osteoarthritis, and recently, cooled RFA has been introduced into the genicular nerve RFA. This narrative review summarized the relevant neuroanatomy and randomized controlled trials regarding conventional and cooled genicular nerve RFA. The effectiveness of conventional and cooled genicular nerve RFA has been observed in several randomized controlled studies. Recent cadaveric studies have improved our understanding of knee joint innervation, including variability in the location of the genicular nerves, leading to a debate regarding the ideal target locations for genicular nerve RFA. Genicular nerve cooled RFA, which produces larger spherical-shaped lesions than conventional genicular nerve RFA, is expected to show a better outcome by effectively creating a lesion on genicular nerves even when an anatomical variation and additionally targeting other additional knee joint nerves.
