Clinical Trial Summary

Although there are different ways of performing genicular nerve radiofrequency on knee pain, to our knowledge, there is no stuies comparing the clinical outcomes of a parallel technique vs. a perpendicular technique. We aimed to compare the effectiveness of these both techniques.

Intervention

Primary	The proportion of patients with a pain reduction of at least 50% compared to baseline expressed by the numerical rating scale (NRS)	The proportion of patients with a pain reduction of at least 50% compared to baseline expressed by the numerical rating scale (NRS) (0-10).The lower the score, the least pain the patient experiences.	6 months after intervention.
Secondary	The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)	WOMAC is a 24-item scale under the headings of pain, stiffness and functional activity. Patients rate the amount of strain, pain felt, and joint stiffness during daily activities between 0 and 4 (0 is the best, 4 is the worst), and the total score is between 0 and 96.	6 months after intervention.
