Objective: The purpose of this article is to understand the principles of cooled radiofrequency ablation (C-RFA) and the description of the procedure of hip CRFA. Cooled radiofrequency ablation uses a constant flow of ambient water circulated through the electrode via a peristaltic pump to maintain a lower tissue temperature by creating a heat sink, but still allowing neurolysis to occur. Cooled radiofrequency ablation lesions are spherical and project several millimeters beyond the electrode tip as compared to thermal-radiofrequency ablation (T-RFA), thereby increasing the probability of successful denervation of the target nerve. Cooled radiofrequency ablation is a preferred technique for ablation of articular branches of the hip joint. Chronic pain in the hip occurs mainly due to osteoarthritis along with other causes like rheumatoid arthritis, osteonecrosis, chronic infectious coxarthrosis, posttraumatic pain, and persistent postoperative pain following total hip arthroplasty (THA).
