Figure 3.
Top, the difference between OMC and biplanar videoradiography for the three rotational axes (Rx, Ry, and Rz) and origin (T) of the independently driven femoral and tibial ACSs. Middle, the rotation difference (FL\EX, AB\AD, IN\EX) between OMC and biplanar videoradiography. Bottom, the translational difference (ME\LA, AN\PO, CO\DI) between OMC and biplanar videoradiography. For all knee joint rotational and translational differences, the data is displayed for the period before contact (A) and the period after contact (B). For each graph, the data is summarized using means plus standard deviations and the brackets represent significant differences (p ≤ 0.05) between groups.
