The Analgesic Efficacy of the Ultrasound-Guided Femoral Articular Branch Block for Ambulatory Hip Arthroscopy: A Randomized-Controlled Trial

Women's College Hospital·interventional·Posted Feb 28, 2018·Updated Apr 1, 2025

In Brief

A clinical study evaluating Femoral Articular Branch Block and Placebo Block for Anesthesia, Regional. Completed, enrolled 94 participants across 1 site.

Detailed Summary

Hip arthroscopy surgery can be associated with significant pain. A regional anesthesia technique, the femoral articular branch block (FAB), has recently been proposed to collectively block terminal femoral and accessory obturator nerve branches to the hip joint with a single injection, theoretically blocking most of the innervation relevant to hip arthroscopy while sparing the main femoral nerve branches to the quadriceps muscles. The investigators aim to demonstrate the analgesic benefits of FAB. The investigators hypothesize that FAB will reduce opioid consumption and improve postoperative quality of recovery in patients having hip arthroscopy. This is a randomized, controlled, double-blind study and half the patients will be randomized to receive the femoral articular branch block and the other half of patients will be randomized to receive a placebo block. A comparison of pain will be made between both groups.

Interventions

Femoral Articular Branch Blockprocedure

Slow injection (3mL aliquots) of local anesthetic solution (20ml of Ropivacaine 0.5%) into the fascia above the iliopsoas muscle (located in the groove between the two bony landmarks - (1)anterior inferior iliac crest and (2)iliopubic eminence).This is done by ultrasound guidance.

Placebo Blockprocedure

Subcutaneous injection of 1ml normal sterile saline
