Our objective was to compare the coronal mechanical axis after total knee replacement (TKR) obtained in three groups of patients subjected to conventional, navigated, and robotic surgery.
Retrospective analysis.
124 knees were included (36 conventional, 41 navigated, 47 robotic). No statistically significant differences were found between the postOp tibiofemoral angle of the conventional, navigated and robotic groups (p = 0.396). A repeated-measure analysis of preOp-to-postOp also found no significant differences (p = 0.387). There were no differences in the proportion of outliers (3-degree) found (p = 0.211). Nevertheless, a higher proportion of patients in the robotic group improved their mechanical alignment, as compared with conventional surgery (p = 0.023), although no differences were found when comparing with navigation (p = 0.121).
No statistically significant differences were found with respect to the postOp alignment achieved. However, statistically significant differences were detected between robotic and conventional surgery when considering the percentage of patients with improved limb alignment.
我们的目的是比较三组接受传统、导航和机器人手术的全膝关节置换（TKR）患者的冠状机械轴。
回顾性分析。
共纳入 124 膝（36 例传统、41 例导航、47 例机器人）。传统、导航和机器人组的术后胫股角无统计学差异（p=0.396）。术前到术后的重复测量分析也无显著差异（p=0.387）。未发现离群值（3 度）的比例存在差异（p=0.211）。然而，与传统手术相比，机器人组有更高比例的患者改善了机械对线（p=0.023），尽管与导航组相比无统计学差异（p=0.121）。
术后获得的对线无统计学差异。然而，当考虑改善肢体对线的患者比例时，机器人与传统手术之间存在统计学显著差异。
