Medial Meniscus Posterior Root Transtibial Pullout Repair With Progressively Tensioning Subcortical Fixation Button

Abstract

We describe a surgical technique to repair medial meniscus posterior root tears through a transtibial pullout repair with a subcortical button for tibial fixation. This technique allows progressive tensioning of the repaired root without losing tension both during suturing of the knots above the button and after the procedure, owing to the specific button configuration.

A 3.2-mm unicortical hole is drilled 2 cm below the transtibial tunnel. The sutures coming from the medial meniscus posterior root have been passed in a specific configuration that allows constant tensioning of the sutures without loosening. Patient in supine position, right knee, arhtroscopic view from standar AL portal.

The the implant handle of the button is removed; the button is deployed in a subcortical manner, and pulling the free tails of the sutures allows the correct flip of the button. Patient in supine position, right knee, arhtroscopic view from standar AL portal.
