Brief summary (from the registry)
This project is one of four components of a thematic project that aims to evaluate the use of ultrasound in regional and infiltration blocks, called "Use of ultrasound in regional blocks and infiltration for the treatment of acute and chronic pain". It aims to evaluate quantitatively and qualitatively the knee pain control in patients with osteoarthritis after neurotomy by saphenous nerve radiofrequency guided by ultrasound , compared to neurotomy by radiofrequency of genicular nerves guided by fluoroscopy . Differences between total consumption of analgesics, side effects of medications , impact on quality of life and functional capacity in patients undergoing saphenous nerve neurotomy by radiofrequency guided by ultrasound compared to neurotomy by radiofrequency of genicular nerves guided by fluoroscopy, will also be evaluated.
