Is severe medial knee osteoarthritis a risk factor for dissatisfaction following medial open-wedge high tibial osteotomy in patients 55 years of age or younger?

Introduction: Although previous studies have shown that severe medial knee osteoarthritis (OA) (Kellgren-Lawrence grade IV) is a risk factor for patient dissatisfaction following medial open-wedge high tibial osteotomy (MOWHTO), it is uncommon to perform arthroplasty as a primary surgical option in patients 55 years of age or younger. Thus, the purpose of our study was to evaluate whether severe medial knee OA is a risk factor for dissatisfaction following MOWHTO depending on patient age based on a cutoff of 55 years.

Material And Methods: We retrospectively reviewed the data of 270 consecutive patients who underwent MOWHTO with a minimum of 2 years of follow up.
