The objective of this study was to determine rates of serious adverse events in patients undergoing revision knee arthroplasty with consideration of the indication for revision and compare these with primary knee arthroplasty. Primary and revision arthroplasty procedures were identified in the national Hospital Episode Statistics and were linked by patient and side. A logistic regression model was used to investigate factors associated with 90-day mortality (primary outcome) and secondary serious adverse outcomes. Urgent indications for revision arthroplasty were defined as infection or fracture; other indications (e.g. loosening, instability, wear) were included in the elective cohort.Abstract
Introduction
Methodology
A revision knee replacement (rKR) network model has been introduced in the UK to improve clinical outcomes for patients and reduce healthcare costs. However, the current practice of different types of surgical unit is not well understood. The aim of this study was to answer: “How complex are rKR cases at a Major Revision Centre (MRC)?” Retrospective cohort study at the Nuffield Orthopaedic Centre, Oxford from 2015 - 2018. Case complexity was classified using the Revision Knee Complexity Classification (RKCC). Referral source, technical details of surgery and hospital admission impact were recorded.Abstract
Introduction
Methodology
Anxiety and depression are risk factors for poor outcome following knee replacement surgery. The aim of this study was to investigate the prevalence of anxiety and depression before and after primary (pKR) and revision knee replacement (rKR). Retrospective cohort study. 315,720 pKR and 12,727 rKR recruited from the NHS Patient Reported Outcome Measures (PROMs) programme from 2013–2021. Anxiety and depression were defined using: (i) Survey question: “Have you been told by a doctor that you have depression? Yes/No”; (ii) EQ-5D anxiety/depression domain. Rates of EQ-5D anxiety/depression were investigated at baseline and at 6-months following surgery. The prevalence of depression was investigated by patient age and gender.Abstract
Introduction
Methodology
Re-revision knee replacement (RR-KR) is complex surgery, with a significant impact on individual patients and health resource use. The aim of this study was to investigate early patient-relevant outcomes following RR-KR. 206 patients (250 knees) undergoing RR-KR were recruited from a major revision centre between 2015–2018. Patient-relevant outcomes assessed were: implant survivorship, complications (90-days), joint function and quality of life (final follow-up). Risk factors for further revision surgery at 1 year were investigated using multiple logistic regression.Abstract
Introduction
Methodology:
Our aim was to investigate trends in the incidence rate and main indication for revision knee replacement (rKR) over the past 15 years in the UK. Cross-sectional study from 2006 - 2020 using data from the National Joint Registry (NJR). Crude incidence rates were calculated using population statistics from the Office for National Statistics.Abstract
