Comparing PENG Block and Local Anesthetic Infiltration for Hip Surgery Pain Relief

Official title: Ultrasound-guided Pericapsular Nerve Group (PENG) Block vs. Intraoperative Local Anesthetic Infiltration (ILAI) for Total Hip Arthroplasty (THA): a Single Center, Non-inferiority Randomized Control Trial Pilot Study.

Run by London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's · NCT05898581 · Data updated 2026-11-12

This study is testing if a new pain relief method called the PENG block works as well as the usual local anesthetic for people having hip replacement surgery.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults over 18 years old who are scheduled for total hip arthroplasty using a direct lateral surgical approach.

Probably not a fit

Patients who may not benefit from this study include those with contraindications for spinal anesthesia or regional analgesia, as well as those undergoing hip revision surgeries.

What this trial studies

This study investigates the effectiveness of the ultrasound-guided pericapsular nerve group (PENG) block compared to traditional intraoperative local anesthetic infiltration for managing postoperative pain in patients undergoing total hip arthroplasty (THA). The PENG block aims to provide effective pain relief while minimizing motor weakness, which is a common side effect of other nerve blocks. The study will include adult patients who are undergoing THA with a direct lateral surgical approach and will assess the analgesic outcomes and cost benefits associated with each method. The goal is to determine if the PENG block can offer non-inferior pain management compared to the standard infiltration technique.

Why it matters

Potential benefit: If successful, this approach could lead to improved pain management and faster recovery for patients undergoing total hip arthroplasty.

How similar studies have gone: While traditional nerve blocks have been widely studied, the PENG block is a newer technique with limited data, making this study a novel exploration in this area.
