Micromotion was found to be dependent on load position. When loaded in the anterior position, the opposite anterior edge tended to lift off to a significantly lower extent than the posterior. Conversely, loading the posterior edge had the reverse effect. This torsional effect is likely due to the roughly centrally located axis of rotation of the implant/bone interface and the planar geometry of the natural tibial plateau. Analysis of variance confirms this statistically significant phenomenon.
