Regarding “Editorial Commentary: Ultrasound Barely Beats Magnetic Resonance Imaging in Knee Anterolateral Ligament Evaluation … But Does This Change the Treatment of the Anterior Cruciate Ligament‐Deficient Knee?”

摘要

We read with great interest the editorial commentary by Rossi titled “Ultrasound Barely Beats Magnetic Resonance Imaging in Knee Anterolateral Ligament Evaluation … But Does This Change the Treatment of the Anterior Cruciate Ligament-Deficient Knee?” We would like to provide additional information on the role of ultrasound in our treatment algorithm and on the methods used in our article1Cavaignac E.

More generally, the root of the problem is defining the indications for lateral extra-articular tenodesis. The indications in various published studies are extreme pivot shift instabilities, revision cases with disruption of secondary restraints, and athletes returning to high-risk sports.7Noyes F.R.
