National Institute for Health and Clinical Excellence (NICE) guidelines recommend the use of total hip replacement (THR) for displaced intracapsular fractured neck of femur (NOF) in cognitively intact patients who were independently mobile prior to the injury. The National Joint Registry for England and Wales (NJR) has collected data on THRs performed since 2003. This retrospective cohort study explores risk factors independently associated with implant failure and perioperative mortality. NJR data recording a THR performed for acute fractured NOF between 2003 and 2010 were analysed. Cox proportional hazards models were used to analyse the extent to which risk of implant revision was related to specific covariates. Multivariable logistic regression was used to analyse factors affecting 90-day perioperative mortality. Significance was taken as p< 0.01.Introduction
Methods
Following in-depth analysis of the market leading brand combinations in which we identified implant influences on risk of revision, we compared revision in patients implanted with different categories of hip replacement in order to find implant with the lowest revision risk, once known flawed options were removed. All patients with osteoarthritis who underwent a hip replacement (2003–2010) using an Exeter-Contemporary (cemented), Corail-Pinnacle (cementless), Exeter-Trident (Hybrid) or a Birmingham Hip resurfacing (BHR) were initially included within the analysis. Operations involving factors that were significant predictors of revision were excluded. Cox proportional hazard models were then used to assess the relative risk of revision for a category of implant (compared with cemented), after adjustment for patient covariates.Introduction
Methods
Total knee replacements (TKR) are among the commonest operations performed in orthopaedic practice. Literature review showed that 10-30% of patients who underwent TKR needed 1-3 units of blood. Tranexamic acid (TXA) has been popularised as an effective way to reduce blood loss and subsequent blood transfusion. Our aim was to investigate the value of TXA in reducing blood loss and blood transfusion after TKR and other clinical outcomes such as deep venous thrombosis (DVT), pulmonary embolism (PE), ischaemic heart diseases and mortality. A systematic review and meta-analysis of published randomised and quasi-randomised trials which used TXA to reduce blood loss in knee arthroplasty were conducted.Introduction
