Twelve different tibial components were compared for fixation. The components included compartmental, anteriorly joined, posterior-cruciate retaining, and one-place with one, two, or three fixation posts; all-plastic or with a metal tray. The apparatus applied compressive load with anterior-posterior force, rotational torque, or varus-valgus moment. The relative deflections, both compressive and distractive, were measured between the component and the bone. The least deflections occurred with one-piece metal-tray components with one or two posts and with one-piece plastic components with a post on each side. Compartmental components deflected the most.
对12种不同的胫骨部件进行了固定比较。这些部件包括间室型、前部连接型、后交叉韧带保留型，以及带有一个、两个或三个固定柱的一体式部件；全塑料或带有金属托盘。该装置施加前后向力、旋转扭矩或内外翻力矩的压缩载荷。测量部件与骨之间的压缩和拉伸相对位移。位移最小的是带有一个或两个固定柱的一体式金属托盘部件以及两侧各有一个固定柱的一体式塑料部件。间室型部件位移最大。
