The story of ShapeMatch® custom-fit cutting guides for primary total knee arthroplasty (TKA) is special compared to other available techniques. First, it was the first such patient-specific instrument (PSI) on the market. Second, the underlying philosophy of kinematic alignment is unique compared to other competitors. Finally, it is the only PSI technique that has been withdrawn from the market.
The objective of this paper is to summarize the history of the ShapeMatch® technology and to review the current literature regarding clinical evidence for kinematically aligned TKA.
In the recent literature, faster rehabilitation, better knee function and higher patient satisfaction are described for kinematically aligned TKA compared to conventional alignment. However, there is also evidence for inaccuracies by using the PSI technology as a possible cause of treatment failures. Due to those problems, this technology was recalled from the market. As an alternative method to achieve kinematic alignment in TKA, manual as well as computer-assisted techniques are currently under development and are discussed here.
与其他现有技术相比，用于初次全膝关节置换术（TKA）的ShapeMatch®定制切割导板的情况较为特殊。首先，它是市场上首款此类患者特异性器械（PSI）。其次，与其他竞争对手相比，其运动学对线的基本理念独特。最后，它是唯一已退出市场的PSI技术。
本文的目的是总结ShapeMatch®技术的历史，并回顾当前关于运动学对线TKA临床证据的文献。
在最近的文献中，与传统对线相比，运动学对线TKA具有更快的康复速度、更好的膝关节功能和更高的患者满意度。然而，也有证据表明使用PSI技术存在不准确之处，这可能是治疗失败的原因。由于这些问题，该技术已从市场上召回。作为在TKA中实现运动学对线的替代方法，目前正在开发手动以及计算机辅助技术，并在此进行讨论。
