Ultrasound-Guided Genicular Nerve Radiofrequency Ablation Therapy: Effectiveness of 5 Nerve Protocols Versus 3 Nerve and 2 Nerve Protocols - A Prospective Randomized Controlled Study
The main symptom of knee osteoarthritis, which occurs after damage to the joint cartilage with age, is pain, but this symptom often becomes chronic. Current conservative treatments have moderate effects on chronic knee pain and their use is limited due to the risk of side effects. In addition to pain, patients also experience other symptoms. As a result of the osteoarthritis process, prorioception in the knee is impaired with a decrease in mechanoreceptors, resulting in loss of balance and an increase in the risk of falling.
• Age between 30-75
• Chronic knee pain that lasts at least 6 months
• Radiographic confirmation of osteoarthritis: Presence of Grade 3 or 4 radiographic changes characterized by significant narrowing in the medial space of the tibiofemoral joint according to the Kellgren-Lawrence classification system
• Knee pain \>40 mm when performing one of the two movements that cause the most severe pain (sitting to standing or going up and down stairs) according to 100 mm VAS
⁃ 50% reduction in VAS with diagnostic genicular nerve block
