Golden Jubilee National Hospital, Clydebank, Scotland, UK. jamiemcc@gmail.com Abstract Perioperative blood loss was compared in 136 patients (2 groups of 68 patients) who underwent total knee arthroplasty (TKA). Blood loss was significantly lower when using a computer-navigated technique in comparison to a method employing intramedullary femoral rods. Total blood loss was calculated from body weight, height and haematocrit change, using a model that has been shown to reliably estimate true blood loss. Average total blood loss [...]
