Brief summary
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| NRS Pain Scores (NRS) | 24 hours post-operatively | Numerical Rating Scale is a self-reported pain assessment, in which a patient indicates their current pain level experienced. Patients can rate their pain on a scale of 0 (no pain) to 10 (worse pain imaginable). Higher scores indicated on this scale may indicate that a patient is experiencing higher pain intensities at that particular point in time. Whereas lower reported scores indicate that the patient is experiencing less intense or minimal pain. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The QOR-15 (Quality of Recovery) | 24 hours post-operatively | Quality of Recovery scores will be obtained 24 hours post-operatively. Scores are reported on an 11 point scale (0 to 10), where 0 = none of the time and 10 = all of the time. Higher scores indicated on the Quality of Recovery scale represent a better recovery outcome. |
