Controversy exists regarding the optimal tibial coronal alignment in total knee arthroplasty. Many believe navigation or robotics are required to set kinematic alignments or to ensure they remain within ‘safe’ limits e.g. maximum 5° varus on the tibia. Given most navigation or robotic systems require the surgeon to identify the ankle malleoli, this study aimed to radiographically analyse standardly used intra-operative landmarks around the ankle, assessing their value in achieving kinematic alignment / setting safety boundaries. Long leg alignment radiographs were analysed independently by two orthopaedic surgeons at two time points, eight weeks apart. Angles were measured between the long axis of the tibia (TB) and: 1. lateral malleolus (TB-LM), 2. lateral border of the talus (TB-LT) and 3. medial aspect of the medial malleolus (TB-MM). Intra- and inter-rater reliabilities were assessed.Abstract

In recent years, CTA has been an effective training adjunct for orthopaedic procedures. ACLR is a complex procedure with a steep learning curve. To design a multimedia CTA learning tool for ACLR using a modified Delphi methodology.Abstract
Introduction
Aim
The aim of this study was to compare the short-term and mid-term outcome of lateral UKRs using a single prosthesis, the AMC Uniglide knee implant. Between 2003 and 2010, seventy lateral unicompartmental knee replacements (mean patient age 63.6±12.7 years) were performed at our unit for isolated lateral compartmental disease. Range of knee motion and functional outcome measures including the American Knee Society (AKSS), Oxford (OKS) and WOMAC scores were recorded from 19 knees at five years' post-operatively and compared to 35 knees at two-years and 53 knees at one-year post-op.Purpose
Methods
Kneeling ability is better in unicompartmental than total knee arthroplasty. There is also an impression that mobile bearing knees achieve better functional outcome than their fixed bearing cousins in unicompartmental and to a lesser extent total joint arthroplasty. In the UK, the market leading unicompartmental replacement is mobile bearing. To analyse kneeling ability after total and unicompartmental knee replacement using mobile and fixed bearing inserts.Introduction
Aim
Assessing medium term outcome of medial Uni compartmental replacement and whether there is a difference in outcome between mobile and fixed bearing variants of the same prosthesis. Knee outcome was assessed in 150 patients (81 male, 69 females, mean age 67.0±10.4yrs) undergoing medial UKR knee (Uniglide, Corin Medical, UK) using either fixed or mobile bearing prosthesis between 2002-2007. All operations were performed by members of the Bristol knee group. All patients were scored using the American Knee Score (AKS), Oxford Knee Score (OKS), and WOMAC pre-operatively and at 2-year follow up. The mobile group (n=93) comprised 43 males and 50 females, aged 62.8±8.9yrs. The fixed bearing group (n=57) comprised 38 males and 19 females, aged 74±8.8yrs.Purpose of the study
