Medial Compartment Fractal Dimensions at Baseline and Follow-up. ACL-injured knee (red), ACL-injured contralateral knee (yellow), ipsilateral control knee (green), contralateral control knee (black). Asterisk denotes statistically significant (P<0.05). FD = Fractal Dimension.
Curves correspond to the poly fit of the whole group. *P-vakues are used to determine statiscally significant differences in polynomial fit of the models, and are presented in Table 3.
