Objectives:
This study aimed to investigate the effects of genicular nerves radiofrequency ablation (GNRFA) treatment on postural stability in patients with knee osteoarthritis.
Patients And Methods:
Twenty-two patients were included in the study. Postural stability was assessed using the walk across test, sit-to-stand test, step-up and over test and modified clinical test of balance in sensory interaction tests with the NeuroCom Balance Master device. A numeric rating scale and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) criterion was used to determine changes pain levels and the functionality. Three evaluations were performed before treatment, 3 weeks and 3 months after treatment.
Results:
After GNRFA, changes in patients' postural stability parameters showed that the lift-up index and the movement time improved significantly in both lower extremities 3 weeks and 3 months. There was a significant reduction in pain levels [8.09±1.01 to 2.41±1.73 in the 3rd week and to 4.18±1.79 in the 3rd month (p<0.0001 for both)]. A significant improvement in WOMAC functionality scores was seen; they started with a mean of 58.69±11.25 at baseline and changed to 23.05±12.08 at the 3rd week and 36.15±16.45 at the 3rd month (p<0.001 for both).
Conclusion:
After GNRFA treatment, the lift-up index and the movement time, which are the dynamic postural stability parameters has improved significantly. These results show that GNRFA treatment contributes positively to postural stability.
