Peripheral Nerve Stimulation of Genicular Nerves Versus Conventional Therapy With Intra-articular Steroid Injection for Chronic Knee Pain: A Prospective, Randomized Pilot Study

Primary Objectives: * To compare the mean change in knee range of motion using goniometry from at 30 days (visit 2) from baseline among the three treatment arms. Secondary Objectives: * To compare the mean change in knee range of motion using goniometry at 60 days (visit 3) and 90 days (visit 4) from baseline among the three treatment arms. * To compare changes in knee pain scores (NRS), WOMAC index, use of opioids (measured in morphine milliequivalent), and incidence of complications and adverse effects at 30 days, 60 days, and 90 days from baseline among the three treatment arms
