Notes: sagittal, frontal, and horizontal planes represent the flexion/extension (knee) and dorsiflexion/plantar flexion (ankle), varus/valgus (knee) and inversion/eversion (ankle), and external/internal rotation (knee and ankle). 95% CI: 95% confidence interval; indicates the significance level ; power of >0.8 represents the probability of detecting if a statistically significant difference exists between the measured variables.
