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.
Both gender patients of age more than 50 years.
Radiographic diagnosis of knee OA with KL level 3 and 4.
Chronic knee pain for more than 6 months
Patients with more than 50% reduction in pain intensity after diagnostic genicular nerve block
Lack of consent
surgery of knee
Patient with BMI more than 40kg/m2
Intra-articular steroid injection or hyaluronic acid in last 3 months
