Brief summary (from the registry)

Genicular nerve neurolysis (GN) constitutes a relatively novel technique, whereby different chemical compounds (i.e. alcohol, phenol) are injected in close proximity to the genicular nerves of the knee joint, with the intention to exert a neurolytic effect by denaturing proteins resulting in Wallerian degeneration distal to the lesion. Based on the preliminary evidence and considering the potential benefits of the technique, we hypothesized that ultrasound-guided genicular chemical neurolysis with phenol is superior in terms of pain relief at 3 months, when compared to intra-articular steroid (IAS) injection.
