Preoperative coronal plane alignment of the knee phenotype does not predict patient-reported outcomes after medial opening-wedge high tibial osteotomy

Introduction

Phenotype-based classification systems have been proposed to characterize coronal alignment and joint-line orientation and to support individualized correction strategies. Although developed primarily for arthroplasty, they are increasingly evaluated in osteotomy populations. This study assessed whether preoperative coronal plane alignment of the knee (CPAK) phenotype predicts patient-reported outcome measures (PROMs) after medial opening-wedge high tibial osteotomy (MOWHTO).
