About

The study is designed to evaluate and compare the efficacy of three needles approach as a new technique in radiofrequency neurotomy of genicular nerve versus the traditional single needle approach as a treatment of advanced knee osteoarthritic pain. Primary outcome:

Pain intensity via the visual analogue score (VAS).
Function and pain via the Oxford Knee Score. Evaluated after 6 months of the procedure

Secondary outcome:

Failure rate.
Incidence of any complication.
Total analgesic requirement during the period of follow up.
