Dynamic Ultrasound Assessment of Axial Extensor Mechanism Alignment in Adolescents With and Without Patellofemoral Instability
Background: Patellofemoral instability (PFI) is common among adolescents. Dynamic evaluation of extensor mechanism alignment during early knee flexion may improve the understanding of recurrent instability risk. Purpose: To evaluate the use of point of care ultrasound (POCUS) to dynamically measure axial extensor mecha...
