Study Summary

Ninety patients with intra-articular hip disorders, mainly osteoarthritis, were randomized to receive fluoroscopy-guided intra-articular steroid injection via the anterior approach (n=30), the anterolateral approach (n=30), or the proximal anterolateral approach (n=30). The primary outcome was successful injection in a single attempt. Secondary outcomes included pain during injection (VAS), radiation exposure, complications, and short-term functional improvement measured by the modified Harris hip score (mHHS). Outcomes were assessed at baseline and 2 weeks post-injection. Overall, the results revealed no significant differences between approaches in single-attempt success, VAS pain, radiation exposure, or mHHS improvement. The study concludes that all three techniques are equally effective and safe, allowing physicians to choose based on preference or patient suitability.
