Abstract

Background: In total knee arthroplasty (TKA), there is a trend towards personalized concepts. This includes the implementation of new technologies and the increasing popularity of individualized alignment strategies.

Targets: The purpose of personalized TKA is to restore the patient's bony anatomy and constitutional alignment, as well as the physiological soft tissue balance and joint kinematics. Modern technologies facilitate a thorough, three-dimensional analysis of the bony structures and the patient's constitutional alignment. Virtual planning enables a simulation component placement, gap balancing and postoperative alignment. After approval of the surgical plan, the technology-aided execution shows a greater accuracy, precision and reproducibility of implant alignment compared to conventional manual instrumentation.

Overview: This article focuses on novel technologies in total knee arthroplasty, including patient-specific instrumentation (PSI), custom implants, navigation and robotics. The purpose of this article is to summarize current evidence, including radiological and functional outcomes, as well as economic aspects. Furthermore, the implementation of novel technologies in the context of personalized alignment strategies will be discussed.

全膝关节置换术的新技术:当前的概念和个性化的治疗策略。
背景:在全膝关节置换术(TKA)中,有一种个性化概念的趋势。这包括新技术的实现和个性化对齐策略的日益普及。目标:个性化TKA的目的是恢复患者的骨骼解剖和体质排列,以及生理软组织平衡和关节运动学。现代技术有助于对骨骼结构和患者体质进行彻底的三维分析。虚拟规划使模拟组件放置,间隙平衡和术后对齐。手术计划批准后,与传统的手动器械相比,技术辅助执行显示出更高的准确性、精密度和可重复性。概述:本文重点介绍全膝关节置换术中的新技术,包括患者专用器械(PSI)、定制植入物、导航和机器人技术。本文的目的是总结目前的证据,包括放射学和功能结果,以及经济方面。此外,还将讨论在个性化对齐策略背景下新技术的实施。
