About

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.

Enrollment: 42 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• patients undergoing a first-time ultrasound-guided unilateral intraarticular hip injection
