A Narrative Review of Ultrasound-Guided Injectate in Lower Extremity Musculoskeletal Disorders

Ultrasound-guided interventions have become a key strategy in managing musculoskeletal disorders by offering real-time anatomical visualization and demonstrating improved injection accuracy compared to landmark-based techniques.However, therapeutic success depends not only on procedural precision but also on the evidence-based selection of injection therapies.Integrating anatomical accuracy with a comprehensive understanding of therapeutic characteristics is essential for optimizing clinical outcomes and ensuring patient safety in clinical practice.This review examines the clinical properties and evidence from recent studies concerning four commonly used injectable modalities: local anesthetics, corticosteroids, prolotherapy, and viscosupplementation.
