BACKGROUND
The purpose of this study was to compare the accuracy of this new HURWA robotic-assisted total knee arthroplasty (TKA) technique to the accuracy of the conventional technique in a sawbone model.
METHODS
The HURWA robotic-assisted TKA system was applied in the robotic group. After bone resection, all of these sawbones were scanned by the use of a structured light scanning system. Measurements of bone resections, femoral coronal and sagittal measurements, and tibial coronal and sagittal measurements were recorded.
RESULTS
Compared to the conventional technique, the HURWA robotic-assisted system significantly improved the accuracy of the bone resection levels and angles. In the robotic group, the accuracy of all of the bone resection levels was below 0.6 mm (with standard deviation [SD] below 0.6 mm), and all of the bone resection angles were below 0.6° (with SD below 0.4°).
CONCLUSION
Our data suggest that this novel HURWA robotic-assisted system can significantly improve the accuracy of bone resection levels and angles.
背景
本研究旨在比较新的 HURWA 机器人辅助全膝关节置换术（TKA）技术与传统技术在仿骨模型中的准确性。
方法
HURWA 机器人辅助 TKA 系统应用于机器人组。骨切除后，所有这些仿骨均采用结构光扫描系统进行扫描。记录骨切除的测量值、股骨冠状和矢状测量值以及胫骨冠状和矢状测量值。
结果
与传统技术相比，HURWA 机器人辅助系统显著提高了骨切除水平和角度的准确性。在机器人组中，所有骨切除水平的准确性均低于 0.6 毫米（标准差低于 0.6 毫米），所有骨切除角度均低于 0.6°（标准差低于 0.4°）。
结论
我们的数据表明，这种新型 HURWA 机器人辅助系统可以显著提高骨切除水平和角度的准确性。
