Table 2.
ACLINT and ACLREC male and female kinematic AUC, rate, and peak vertical GRF results. A two-way analysis of variance was performed on each set of data. Statistically significant differences (p≤0.05) are highlighted using a dark gray background fill. Near statistical significance (p≤0.10) is highlighted using a light gray background fill. Pair-wise comparisons were made using the Holm-Sidak method when a significant (or near significant) gender and ACL reconstruction status interaction was determined. These results, denoted by the * or **, are shown in the bottom row of the table. The data presented in the parentheses (ME/LA and AN/PO AUC, AN/PO rates) are the raw translational values in millimeters. Finally, it should be noted that the kinematic data presented in Table 2 were obtained from the biplanar videoradiography system. Supplemental Digital Content 1 *.pdf
