Comparison of ultrasound guidance with landmark guidance for symptomatic benefits in knee, hip and hand osteoarthritis: Systematic review and meta‐analysis of randomised controlled trials.

Introduction: More than half of the patients with moderate and severe osteoarthritis (OA) report unsatisfactory pain relief, requiring consideration of intra‐articular (IA) injections as the second‐line management. Ultrasound‐guided IA injection has proven evidence of higher accuracy in administering IA injectates into the joints than landmark‐guided or blind IA injections. However, questions remain about translating higher accuracy rates of ultrasound‐guided injection into better clinical improvements. Therefore, we examined the symptomatic benefits (pain, function and patient satisfaction) of ultrasound‐guided injection in knee, hip and hand OA compared with blind injections by synthesising a systematic review and meta‐analysis of randomised controlled trials (RCT). Methods: PubMed, Medline and Embase databases were searched for eligible studies from their inception to August 28, 2023. Results: Out of 295 records, our meta‐analysis included four RCTs (338 patients with knee OA), demonstrating significant improvement in procedural pain [−0.89 (95% CI −1.25, −0.53)], pain at follow‐up [−0.51 (95% CI −0.98, −0.04)] and function [1.30 (95% CI 0.86, 1.73)], favouring ultrasound guidance. One single study showed higher patient satisfaction with ultrasound guidance. Conclusion: Ultrasound‐guided IA injection provided superior clinical outcomes compared with landmark‐guided IA injection. [ABSTRACT FROM AUTHOR]
