To identify the incidence and reasons for revision of the Oxford prosthesis (OXF) in New Zealand. Review and compare UKA and TKA data including patient-generated Oxford scores after operation.Purpose
Methods
The New Zealand Joint Registry was started in 1999. An audit in 2009 showed 98% compliance. Ten year results were published in 2009. For Total Hip Replacement it showed that dislocation was the most common cause for revision (35%). We reviewed the rate of revision for dislocation in the two most common diagnostic groups, Osteoarthritis (86%) and Acute Fracture NOF (3.6%) relative to the two most common surgical approaches, posterior and lateral. We also sought to analyse whether larger femoral head sizes decreased the dislocation rate.Background
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
