The aim of this study is to evaluate whether computer-assisted navigated TKA reduces perioperative blood loss. Patients were randomly divided into 2 groups and underwent either a conventional TKA (n = 40) or a TKA with computer-assisted navigation (n = 40). Perioperative blood loss was evaluated by laboratory parameters, postoperative drain output and number of required transfusions. Change in hemoglobin concentration and in hematocrit levels was similar. Also, there was no statistically significant difference in drain output and in the number of transfused units. The results of this study showed that TKA with computer-assisted navigation is similar to the conventional TKA regarding perioperative hemorrhage.
本研究的目的是评估计算机辅助导航全膝关节置换术(TKA)是否能减少围手术期失血。患者被随机分为两组,分别接受传统全膝关节置换术(n = 40)或计算机辅助导航全膝关节置换术(n = 40)。通过实验室参数、术后引流量和所需输血次数评估围手术期失血情况。血红蛋白浓度和血细胞比容水平的变化相似。此外,引流量和输血量在统计学上无显著差异。本研究结果表明,计算机辅助导航全膝关节置换术在围手术期出血方面与传统全膝关节置换术相似。
