About

Arthroscopic hip surgeries are increasingly being performed as both diagnostic and therapeutic interventions. These procedures are considerably painful, thus requiring the proper pain management techniques in order to provide patient satisfaction and sufficient pain control. Articular branch blocks have not been evaluated for their use in hip arthroscopy, but have potential advantages of blocking the sensory innervation of the entire hip joint, with minimal impact on motor innervation compared to alternative blocks.

This current study aims to evaluate the efficacy of using preoperative fluoroscopic-guided blockade of articular branches of the femoral and obturator nerves for analgesic management of patients undergoing arthroscopy compared to a saline sham block.

The utility of pre-operative hip articular branch block (ABB) prior to hip arthroscopy will provide superior pain management postoperatively compared to a saline sham block. We hypothesize that the ABB (Articular Branch Block) will reduce the area under the NRS pain scores by time curve (AUC) and decreased oral opioid milligram equivalent use in the first 24 hours post-operatively.
