Brief summary

In this single-center randomized controlled trial, subjects undergoing a first-time ultrasound-guided unilateral intraarticular hip injection will be randomized into one of two groups: hip injection with prior local anesthesia (With LA) or hip injection without prior local anesthesia (Without LA). Visual analog scale (VAS) pain scores (0-100) will be collected after the local anesthesia injection (With LA group) and intraarticular hip injection (both groups). The primary outcome measure for comparison between the two groups will be VAS score for the intraarticular hip injection.

Interventions

PROCEDUREUltrasound guided injection

All intraarticular hip injections will be performed under real-time ultrasound guidance using a GE LOGIQ P9 ultrasound machine with a C1-5-RS 1-5 MHz curvilinear transducer (GE Healthcare, Chicago, IL, USA). For the procedure, patients will be placed in a supine position. The curvilinear transducer and ultrasound machine will be used to visualize the anterior aspect of the hip joint in a sagittal oblique plane. Sterile technique will be used to perform the procedure.
