Distal tubercle osteotomy in medial opening-wedge high tibial osteotomy is superior in rotational alignment changes compared to proximal tubercle osteotomy: a propensity score-matched analysis.

ABSTRACT:

Background

Rotational alignment changes following high tibial osteotomy (HTO) can alter patellofemoral joint biomechanics, potentially leading to adverse clinical outcomes. This study aimed to compare rotational alignment changes and clinical outcomes between two different types of biplanar medial opening-wedge HTO: proximal tubercle osteotomy (PT-HTO) and distal tubercle osteotomy (DT-HTO).

Methods

A total of 178 patients who underwent medial opening-wedge HTO for medial compartment osteoarthritis between January 2020 and March 2023, with a minimum follow-up of two years, were retrospectively identified. Patients were stratified into two groups based on the direction of the second-plane osteotomy: PT-HTO (n = 136) and DT-HTO (n = 42). Propensity score matching was performed
