Comparison of a patient-specific instrument and conventional high tibial Osteotomy: Accuracy of correction target and prevention of posterior tibial slope change.

ABSTRACT:

Background

High tibial osteotomy (HTO) is crucial for managing medial compartmental knee osteoarthritis. Precision in achieving the medial proximal tibial angle (MPTA) correction and maintenance of posterior tibial slope (PTS) is essential for clinical success. This study aims to compare the use of 3D-printed patient-specific instruments (PSI) to conventional HTO to achieve precise MPTA correction and maintenance of PTS, aiming to enhance surgical outcomes in HTO patients.

Methods

Among 104 patients who underwent HTO between September 2018 and July 2021, 60 met the inclusion criteria and were categorized into a PSI group (30 cases) and conventional method group (30 cases). Radiological outcomes included estimated and postoperative MPTA values, along with preoperative and pos
