The use of a mobile-bearing knee system is routine in modern total knee arthroplasty (TKA). There are indications for use of a mobile-bearing TKA for a growing number of patients. The design, however, was not always well appreciated. Fears of perioperative difficulties and lack of understanding of the design principles limited the acceptance of mobile-bearing technology. Recent evidence has shown that use of mobile-bearing prostheses in TKA has increased, and today, nearly three decades after its introduction, the mobile-bearing design remains relavent and important. The theories behind the design of mobile-bearing prostheses have shown in clinical practice what many already believed to be true: mobile-bearing TKA, when performed correctly, is reliable, and capable of providing substantial benefit for patients.
在现代全膝关节置换术（TKA）中，使用活动平台膝关节系统已成为常规操作。越来越多的患者有使用活动平台TKA的指征。然而，其设计并非一直都能得到充分理解。对围手术期困难的担忧以及对设计原理缺乏了解限制了活动平台技术的接受度。最近的证据表明，TKA中活动平台假体的使用有所增加，如今，在其引入近三十年后，活动平台设计仍然具有相关性和重要性。活动平台假体设计背后的理论在临床实践中证实了许多人已经相信的事实：正确实施的活动平台TKA是可靠的，并且能够为患者带来显著益处。
