PENG Block for Arthroscopic Hip Surgery

Pericapsular Nerve Group (PENG) Block for Arthroscopic Hip Surgery: A Randomized, Placebo-controlled Trial

This randomized, double-blinded, placebo-controlled trial seeks to evaluate the analgesic efficacy of the pericapsular nerve group block in the setting of outpatient hip arthroscopy.

The pericapsular nerve group, or PENG block, has been recently described and shows promise in providing analgesia to the hip joint. The analgesic value of this block in the setting of hip arthroscopy is unknown. This study aims to compare a preoperative PENG block to placebo block prior to outpatient hip arthroscopy under general anesthesia. The primary outcome measure is immediate postoperative pain as measured by numerical rating score in the post-anesthesia care unit (PACU). Secondary outcomes include opioid consumption, opioid-related adverse events, patient satisfaction, chronic opioid usage, and pain scores at other time points.

Inclusion Criteria:

• Patients > 18 years old undergoing unilateral hip arthroscopy at the outpatient surgery center.

Exclusion Criteria:

• refusal to participate
• < 18 yo
• Chronic opioid use
• localized infection
