The treatment of displaced femoral neck fractures in elderly patients is under debate. Hemiarthroplasty is a recognised treatment for elderly patients with reduced capacity for mobilisation. Controversy exists around cemented or uncemented implants for hemiarthroplasty in this population. The aim of this study is to investigate outcomes of cemented vs uncemented hemiarthroplasty implants to two years post operation. All elderly patients presenting to one institution with a displaced subcapital neck of femur fracture were offered inclusion. One hundred and sixty patients (mean age, 85 years) with acute displaced femoral neck fractures were randomly allocated to be treated with cemented Exeter, or uncemented Zweymüller Alloclassic Hemiarthroplasty. Clinical and radiologic follow-up to two years with the main outcome measurements being pain, mortality, mobility, complications, reoperations, and quality of life using validated scores recorded by a blinded outcome assessor.Introduction
Methods
There has been recent interest in gender-specific arthroplasty implant design but little evidence to support their use. We hypothesised that outcomes among arthroplasty patients are affected by gender. Patients were retrospectively identified from a prospective database of TJRs performed at one centre among six surgeons over a ten-year period (1998-2008). Demographics, pre-operative and 1-year clinical Knee Society (KSS), Harris Hip (HHS), and Oxford scores were collected. Gender differences were analysed using independent samples t-test and chi-square.Purpose
Methods
Reducing infection in total joint replacement by using ultra clean air and protective enclosed suits (space suits) has become the standard in many operating theatres without good supporting evidence. This study examined the impact of laminar flow and space suits on the rate of revision for early infection following total hip (THR) and knee (TKR) replacement. We used the 10-year results of the New Zealand Joint Registry to compare the rates of revision for early infection between laminar flow and conventional theatres both with and without the use of space suits. We separated hospitals and surgeons who had worked with and without space suits in both environments to exclude other confounding variables.Introduction
