This article describes tibiofemoral contact area measurement results from tests on 1 commercial total knee arthroplasty (TKA) using 2 experimental methods-fuji film and diagnostic ultrasound. The study presents a novel diagnostic ultrasound technique developed specifically for measuring TKA contact areas. Because most experimental investigations have been concerned with interimplant comparison, this article is one of few parametric TKA studies in the literature. Fuji film and ultrasound provide lower and upper bound contact area measurements based on their physical operating principles; this implies that no single measurement method can be relied on exclusively to glean contact area data. Designers should be cautious in using contact area and contact stress as the exclusive predictors of TKA failure.
本文介绍了使用富士胶片和诊断超声这两种实验方法，对1种商用全膝关节置换术（TKA）进行测试所得的胫股接触面积测量结果。该研究提出了一种专门为测量TKA接触面积而开发的新型诊断超声技术。由于大多数实验研究都关注植入物之间的比较，因此本文是文献中为数不多的参数化TKA研究之一。富士胶片和超声根据其物理工作原理提供了接触面积测量的下限和上限；这意味着不能仅依靠单一测量方法来收集接触面积数据。设计者在将接触面积和接触应力作为TKA失败的唯一预测指标时应谨慎。
