Abstract:

Objective: To study the efficacy of radiofrequency ablation for treating pain in patients with advanced knee osteoarthritis. Study Design: Quasi-experimental study. Place and Duration of Study: Pain Clinic of Armed Forces Institute of Rehabilitation Medicine Rawalpindi, from Sep 2019 to Feb 2020. Methodology: Patients of more than 50 years of age, with grade III and IV Kellgren-Lawrence grades of knee osteoarthritis and at least a score of 4 for three months on the numerical rating scale were included in the study. Measurements were taken on the numerical rating scale and Western Ontario and McMaster universities osteoarthritis index before and four weeks after fluoroscopy-guided radiofrequency ablation of three genicular nerves around the knee joint. Results: Fifty patients (mean age: 62 ± 6.5 years) were included in the study. The median numerical rating scale scores before and after intervention were 9 (Interquartile range: 7-10) and 5 (Interquartile range: 2-8), respectively (p0.05). Conclusion: Radiofrequency ablation of genicular nerves around the knee joint significantly improves pain, stiffness and body function in patients with advanced knee osteoarthritis and results are better in women.
