Chronic Knee Osteoarthritis Clinical Trial
Official title:
Effect of Monopolar Radiofrequency Ablation for Genicular Nerves Compared to Bipolar Radiofrequency Ablation Using Ultrasound in Treating Chronic Knee Osteoarthritis
Radiofrequency ablation of the genicular nerves using ultrasound is safe and effective for
treating intractable knee osteoarthritis pain by using either monopolar or bipolar
radiofrequency ablation.
This technique is based on anatomical studies demonstrating that genicular nerves are
accompanied by genicular arteries. Ultrasound-guided RF genicular ablation yielded both
significant reductions in knee pain and improvements in functional capacity.
The aim of this study is to compare between ultrasound guided monopolar and bipolar
radiofrequency ablation in chronic knee osteoarthritis.
Osteoarthritis of knee joint is one of the most common disease conditions with advanced age
and leads to considerable morbidity in terms of pain, stiffness, limitation in functions,
disturbance in sleep and psychological disturbance
A diagnostic genicular nerve block (GNB) with local anesthetic is performed before RF
genicular ablation, and a successful response to GNB is considered to indicate the need for
RF genicular ablation
