Reduction of Postoperative Hip Arthroscopy Pain With an Ultrasound-Guided Fascia Iliaca Block: A Prospective Randomized Controlled Trial.

Background: Ultrasound-guided fascia iliaca blocks have been used for pain control after hip arthroscopy. There is little evidence regarding their effectiveness in comparison with other pain control modalities in patients who have undergone hip arthroscopy.

Purpose: To compare the efficacy of ultrasound-guided fascia iliac block with intra-articular ropivacaine in controlling pain after hip arthroscopy.
