Changes in patellar baja progress until 3 months after medial open-wedge high tibial osteotomy

Abstract

Purpose: The purpose of this study was to evaluate sequential patellar height changes as well as the factors leading to these changes after medial open-wedge high tibial osteotomy (MOWHTO). Methods: The study cohort constituted 37 knees from 36 patients who underwent MOWHTO for varus knee. The Caton–Deschamps index (CDI) for patellar height was measured preoperatively and at 2 weeks and 3, 6, and 12 months postoperatively. The factors related to sequential changes in patellar height were evaluated. Results: Significant differences were observed between preoperative CDI and postoperative CDI at all time points (p
