Use of Dynamic Ultrasonography in the Evaluation of Meniscal Extrusion: A Technical Report

Meniscal root tears can lead to extrusion with biomechanical consequences similar to total meniscectomy. This report describes a protocol for bedside ultrasonography (real-time ultrasound imaging at the point of care) for dynamic assessment of meniscal displacement before and after surgery. Using a 5-12 MHz linear probe, the meniscus is evaluated under stress and motion to assess reducibility and repair integrity. Unlike MRI, this method offers real-time, load-responsive imaging. Dynamic ultrasound serves as a practical adjunct to MRI, aiding surgical planning and improving postoperative assessment in patients with meniscal root injuries.
