Overview
Brief Summary
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.

Arms & Interventions
Group B
Intervention group in which genicular nerves radiofrequency ablation will be done with the help ultrasound guidance.
Intervention: Ultrasound Guided (Procedure)
Group A
Control group in which genicular nerves radiofrequency ablation will be done with the help of fluoroscopic guidance.
Intervention: Fluoroscope Guided (Procedure)
Outcomes
Primary Outcomes
Effectiveness of Block
Time Frame: Post procedure 2 weeks, then follow up after 2, 4 and 6 months.
Block will be considered effective if decrease in pain score from baseline is \>50% at six months. And this will measure by using the 11-point Numeric Rating Scale (NRS) where 0 = no pain and 10 = worst imaginable pain.
Secondary Outcomes
- Functional Improvement after block(6 months)
