Higher patient's expectations and dissatisfaction following total knee arthroplasty are well-documented phenomena. Despite the implications of different patients' related factors both modifiable and nonmodifiable, in the last decade a lot of emphasis has been focused on surgical technique, implant alignment and stability both as a cause and a potential solution of several problems.
Different alignment and balancing techniques have been recently described and the introduction of new technologies such as computer and robotic-assisted surgery have been the basis for their optimization. In this paper, the surgical technique of the ROSA Knee System will be described focusing on the potential alignment options and the ligament balancing technique. The current literature available about the system will also be analyzed.
The ROSA® robotic system have been recently introduced in the market and presents specific and peculiar features to optimize ligament balancing and an individualized alignment of the implant in a three dimensional prospective.
The system is showing a favourable gap balancing technique and the possibility to create an individualized alignment. Preliminary results have now been shown in the literature both on the accuracy of the system and on clinical outcomes.
Preliminary results are promising both in terms of accuracy of the system and of clinical outcomes.
全膝关节置换术后患者的期望和不满是有据可查的现象。尽管不同患者相关因素（可改变和不可改变）的影响很大，但在过去十年中，人们已经将大量的注意力集中在手术技术、植入物的对线和稳定性上，这些因素既是导致多种问题的原因，也是潜在的解决方案。
最近已经描述了不同的对线和平衡技术，而计算机和机器人辅助手术等新技术的引入则为其优化提供了基础。本文将介绍 ROSA 膝关节系统的手术技术，重点介绍潜在的对线选择和韧带平衡技术。同时也将分析该系统目前的文献。
ROSA®机器人系统最近已在市场上推出，具有独特的特点，可以优化韧带平衡和三维前瞻性的植入物个体化对线。
该系统显示出良好的间隙平衡技术和实现个体化对线的可能性。目前该系统的准确性和临床结果已经在文献中得到初步展示。
初步结果在系统准确性和临床结果方面都很有前景。
