Comparison of Two Injection Techniques for Intra-articular Hip Injections.

40 patients with hip pain were randomized to receive an ultrasound-guided intra-articular corticosteroid injection with or without the use of an automated delivery system. The objective of this trial was to determine if the automated delivery was associated with significantly superior clinical efficiency when compared to a traditional injection technique. Outcome measures were evaluated over a 12-week post-treatment follow-up period and included pain, hip function, activities of daily living, sport performance throughout, and time to perform the injection. The results of the trial indicated that the majority of clinical outcomes of interest were comparable between study groups, with the exception of the Sport-Specific Subscale of the Hip Outcome score (HOS-SSS), which favoured the conventional group at 6 weeks. Additionally, injection time was observed to be significantly longer for patients in the automated group.
