Figure 6. Y-axis: anterior translation of contact points (mm) , X-axis: knee flexion (°). Left graph: Flexion phase. Right graph: Extension phase. Thick line: ACLD knee. Thin line: Contralateral knee. There were significant differences at 5, 10, 15° of knee flexion in the extension phase. Asterisk denotes P value < 0.05 by repeated measures ANOVA. Tukey’s test was used for post-hoc pair wise comparisons. Error bars represent ± 1 standard deviation.
