Phenol Neurolysis vs Radiofrequency Thermocoagulation for Knee Arthroplasty Pain

This study focuses on comparing two methods for managing pain in individuals who have undergone knee replacement surgery due to chronic knee osteoarthritis. The two methods are Phenol Neurolysis and Radiofrequency Thermocoagulation, both applied to the geniculate nerve. The study involves 140 patients who will be evaluated at Adnan Menderes University Hospitals. It's important to note that all participants must be over 18 years old and have undergone knee arthroplasty for chronic knee osteoarthritis. The study aims to find a more effective method to manage post-surgery pain, potentially improving the quality of life for individuals with knee osteoarthritis. During the study, patients will be positioned comfortably and the procedures will be performed in a sterile environment. For the Radiofrequency Thermocoagulation group, a special cannula will be used to deliver the treatment to each geniculate nerve. In the Phenol Neurolysis group, a different type of needle will be used to inject a mixture of bupivacaine and phenol into each geniculate nerve. The effectiveness of both methods will be measured by the reduction in pain at 1, 3, and 6 months after the procedure. A decrease in pain of 50% or more will be considered significant. Any complications or side effects after the procedure will also be recorded.
