Figure 4
Distal movement of the stem relative to the bone. Micromotion was calculated as the average amplitude of the cyclic motion during the last 200 cycles of each loading step (Fap = 0, Fap = 0.3 BW, and Fap = 0.6 BW). Migration was the cumulative stem displacement at the end of each step, with respect to its position at cycle 100.
