The aim of this study was to determine the effects of using the Bellovac autologous blood salvage system on blood transfusion requirements, adverse event rate, post-operative length of stay (POLOS) and mobilisation in patients who have undergone a total knee replacement. This is a retrospective cohort study of 471 patients who underwent a total knee replacement (TKR) at our institution between January 2008 and August 2009. All patients received an autologous blood salvage drain in theatre. Their medical records were reviewed and a database created to assess the efficacy of the blood salvage system.Aim
