Knee Osteoarthritis
Conditions
Brief 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.
Interventions
PROCEDUREPerpendicular Group
Radiofrequency ablation was applied to the perpendicular group by placing the tip of electrode perpendicularly to contact the genicular nerves.
PROCEDUREParallel Group
Radiofrequency ablation was applied to the parallel group by placing the electrode lay parallel to contact the genicular nerves.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The proportion of patients with a pain reduction of at least 50% compared to baseline expressed by the numerical rating scale (NRS) | 6 months after intervention. | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) | 6 months after intervention. | 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. |
