Comparison of the Efficacy of Phenol Block and Corticosteroid-Local Anesthetic Block Applied to the Genicular Nerve

Comparison of the Efficacy of Ultrasound-Guided Phenol Block and Corticosteroid-Local Anesthetic Block Applied to the Genicular Nerve in Patients With Knee Osteoarthritis

There are different neurolysis methods. Aim of this study is to compare two different methods, phenol block and corticosteroid local anesthetic block.

Knee osteoarthritis is one of most frequent reason of knee pain. There are different treatment methods such as analgesic drug treatment, physical therapy techniques, intraarticular injections and neurolysis techniques. In this study, we will compare neurolysis techniques these are phenol block and corticosteroid local anesthetic block.

• Non responsive to life style change, weight control, exercises program, medical treatment and the other conservative treatments (physical therapy, intraarticular injections)
• Decreasing at NRS score more than %50 after diagnostic block
• Those who accept the consent form
