Effect of asymmetric anterior and posterior wedge openings on medial and lateral posterior tibial slope in medial open wedge high tibial osteotomy: An in vitro study on sheep tibias

In MOWHTO, applying a larger posterior opening than anterior results in greater lateral PTS reduction compared to the medial side, particularly when the hinge is located in the anterolateral cortex. These findings highlight the importance of wedge configura tion and hinge integrity in controlling sagittal plane alignment. Cite this article as: Yahyaoğlu A, Ergün S, Eceviz E.
