Comparison of ultrasound- and fluoroscopy-guided intra-articular corticosteroid injections for hip osteoarthritis

Both US-guided and FL-guided steroid injections resulted in significant pain reduction and improved functionality in patients with osteoarthritis. No clear superiority was observed between the two techniques. Treatment was most effective in patients at earlier stages of the disease, with efficacy declining as the disease advanced. Additionally, US is a safer imaging modality compared to FL, as it does not involve exposure to ionizing radiation.
