✦ Synopsis

Out of this

number, 21 were lost to follow-up because of death (in 16), revision (2) due to infection, and failure to attend (3). The post-operative alignment of 101 prostheses were compared to the incidence of radiolucencies around the tibial component at 5 years follow-up.

The mechanical axis was used as a reference.

The mean alignment was 0.99 valgus with a standard deviation of 2.48". Some 72% of knees were within P and 94% within 5" of true alignment.

Using two methods of assessing radiolucencies there was a non-signaficant relationship between the alignment and radiolucencies.

The alignment tolerance with this prosthesis is, therefme, at least 5".

## Abstract This study measured the vertical displacement of three kinds of cementless tibial components [Porous Coated Anatomical (PCA), Tricon, and Whiteside], under eccentric loading up to 2,225 N. Displacement between the tibial tray and the proximal tibia was measured with linear variable diff
