CAN COMPUTER ASSISTED SURGERY REDUCE BLOOD LOSS AFTER TOTAL
KNEE REPLACEMENT?

Computer aided surgery is increasingly used to improve the accuracy of implant
placement and alignment after total knee replacement. In navigated knee
replacement, trackers are used instead of intramedullary jigs for alignment and hence
it is anticipated that the blood loss would be lower in comparison to conventional
knee replacement. A retrospective study was performed to analyse the difference in
blood loss after navigated and non-navigated total knee replacement. All consecutive
patients who underwent total knee replacement between September 2006 and
September 2009 by a single surgeon were considered to be included in the study.
Patients undergoing revision surgery and complex primary knee replacement
requiring bone grafts and osteotomy were excluded. A standard proforma was used
and details noted from the pre-operative care plan, anaesthetic record, case notes
and laboratory results. There were 147 patients with 74 males and 73 females. The
average age was 68.9 (40-90) years. The pre-operative and the post-operative
haemoglobin were compared between the navigated and the non-navigated groups
and the results presented.
