Abstract：Objective To compare difference of perioperative blood loss between minimally invasive surgery total knee arthroplasty (MIS-TKA) and conventional TKA (C-TKA). Methods A retrospective study was conducted on perioperative bleeding volume in 84 patients undergone unilateral TKA from January 2009 to January 2012. The patients were divided to minimally invasive group (42 patients) and conventional group (42 patients）, according to surgical approaches. Perioperative blood loss (evident + occult hemorrhage) was calculated. Blood loss and blood requirement in the two groups were analyzed and compared as well. Results Mean blood loss was (1 466±493) ml in the conventional group and (1 379±475) ml in the minimally invasive group (P>0.05). Moreover, mean blood requirement in the two groups was (223±208) ml and (257±239) ml respectively (P>0.05). Conclusion MIS-TKA can not reduce perioperative blood loss.
