Abstract

Introduction

Surgery in patients with high body mass index (BMI) is more technically challenging and associated with increased complications post-operatively. Inferior clinical and functional mid-term results for high BMI patients undergoing high tibial osteotomy (HTO) relative to normal weight patients have been reported. This study discusses the clinical, radiological and functional outcomes of HTO surgery in patients with a high BMI.

Method

This is a retrospective study on patients undergoing HTO surgery using the Tomofix anatomical MHT plate between 2017 and 2022, with follow-up period of up to 5 years. The cohort was divided: non-obese (BMI <30 kg/m2) and obese (BMI>30 kg/m2). Pre and post operative functional scores were collected: Oxford Knee Score (OKS), EuroQol-5D and Tegner. Complications, plate survivorship and Mikulicz point recorded.

Abstract

Introduction

In patients with bilateral unicompartmental knee osteoarthritis, simultaneous bilateral surgery is cost effective, with both patient-specific and wider socioeconomic benefits. There are concerns however regarding higher complication rates with bilateral knee surgery. This study compares simultaneous bilateral unicompartmental knee arthroplasty (UKA), to single side UKA in terms of complications and outcomes.

Methodology

This is a retrospective case-control study of single side medial UKA patients (controls) and simultaneous bilateral medial UKA patients (cases). All patients underwent surgery between 2018 and 2022 by a single surgeon. The two cohorts were compared for perioperative blood loss (PBL), length of stay (LOS), complications (infections, blood clots, wound problems), Oxford Knee Score improvement (OKS) and revision surgery, with a follow-up period of up to 5 years.

Abstract

Introduction

Compared to the standard Tomofix plate, the anatomical Tomofix medial high tibial (MHT) plate has been shown to improve anatomical fit and post correction tibial contour, following high tibial osteotomy (HTO). Clinical data on surgical complications, osteotomy union rates and survivorship with the anatomical Tomofix MHT plate however remain limited. This study reports mid-term results of HTO surgery, using the anatomical Tomofix MHT plate.

Methods

All patients undergoing HTO surgery using the anatomical Tomofix MHT plate between 2017 and 2022 were included in the study. Data on complications, osteotomy union rates and survivorship were collected prospectively and retrospectively analysed.
