Image Guided Genicular Nerve Radiofrequency Ablation for Chronic Knee Osteoarthritis

The goal of this prospective randomized control trial is to provide continued pain relief, classically long-lasting 3 to12 months, and enhanced function in patients following: both gender; male and female, age group; \>50yr, healthy volunteers along with Radiographic diagnosis of knee OA with KL grade 3 and 4 in addition of Chronic knee pain ≥ 6 months and patients with ≥50% decrease in pain strength after diagnostic genicular nerve block. The main question it aims to answer is: Is ultrasound-guided genicular nerve RFA more efficient in lowering pain intensity at six months contrasted with fluoroscopic guided method in patients with chronic knee osteoarthritis? Researchers will compare Group A (Fluoroscopic) to Group B (Ultrasound) to see comparison in efficiency of ultrasound guided against fluoroscopic guided genicular nerves block for decrease in pain intensity and functional improvement.
