Today's most basic and important total knee replacement design concepts arose out of an earlier era in which 2 distinct approaches emerged, functional and anatomic. Functional approaches simplified knee kinetics, were easier to implant, and gained widespread popularity, in part, from their inventory control. Anatomic approaches were an attempt to recreate normal knee motion with low prosthetic contact stress. Historically, however, they became impractical to produce because of the cost of maintaining a wide variety of anatomic knee implants. New customized designs may return the anatomic design to favor due to several key features that borrow anatomic principles developed in the past, and improved with new ideas.
今天最基本和重要的全膝关节置换设计理念源于早期的两个截然不同的方法出现，功能和解剖。功能方法简化了膝关节动力学，更容易植入，并获得了广泛的普及，部分原因是它们的库存控制。解剖方法试图用低假体接触应力来重建正常的膝关节运动。然而，从历史上看，由于维持各种解剖膝关节植入物的成本，它们变得不切实际。新的定制设计可能会因为几个关键特征而使解剖设计重新受到青睐，这些特征借鉴了过去开发的解剖学原理，并通过新的理念得到了改进。
