Unicompartmental knee arthroplasty provides a good alternative to total knee arthroplasty in patients with isolated medial compartment osteoarthritis. Reported ten-year survival for the Oxford medial unicompartmental knee arthroplasty is variable, ranging from 80.2% to 97.7% in the originator series. The aim of this study was to determine the survival and reasons for revision of the Oxford medial unicompartmental knee arthroplasty when performed at a specialist orthopaedic centre. Details of consecutive patients undergoing Oxford unicompartmental knee arthroplasty at our centre between January 2000 and December 2009 were collected prospectively. Failure of the implant was defined as conversion to total knee arthroplasty. Survival was determined using the Kaplan-Meier method.Background

The purpose of this study was to evaluate the independent contributions of surgeon procedure volume, hospital procedure volume, and standardisation of care on short-term post-operative outcomes and resource utilisation in lower-extremity total joint arthroplasty. An analysis of 182,146 consecutive patients who underwent primary total joint arthroplasty was performed with use of data entered into the Perspective database by 3421 physicians from 312 hospitals over a two-year period. Adherence to evidence-based processes of care was defined by administration of appropriate perioperative antibiotic prophylaxis, beta blockade, and venous thromboembolism prophylaxis. Patient outcomes included mortality, length of hospital stay, discharge disposition, surgical complications, readmissions, and reoperations within the first 30 days after discharge. Hierarchical models were used to estimate effects of hospital and surgeon procedure volume and standardisation on individual and combined surgical outcomes and length of stay.Background
Methods
The UKITE was started nationally as a yearly, online, curriculum-based, self-assessment examination in 2007 for the orthopaedic trainees. It remains free if trainees contribute questions. The examination has matured, expanded its services and established over 3 years. The UKITE is funded by DePuy. The data for the last 3 years of UKITE examinations were collected and analysed using Microsoft Excel.Background
