Ultrasound-Guided Interventions for the Knee

Ultrasound imaging of the knee is a highly valuable modality that enhances diagnostic accuracy and optimizes the precision of injection therapy. This article reviews the application of ultrasound in various knee interventions, including intra-articular injections, treatments for prepatellar bursitis and patellar ligament tendinopathy, pes anserinus, iliotibial band procedures, and guidance for popliteal fossa pathologies. Detailed guidance is provided on probe selection, patient positioning, and procedural techniques for specific anatomical targets. Key considerations include optimizing needle placement using in-plane and out-of-plane techniques, ensuring accurate interventions, minimizing risks such as cartilage injury or vascular complications, and achieving effective therapeutic delivery. Text is supplemented with anatomical notes.
