  1. Values are expressed as number (percentage). Percentage of total remodeling that occurred at each time point in the anterior, superior, posterior, and lateral regions. The differences in frequency between medial and lateral parts of the anterior, superior, posterior, and lateral regions are indicated by the p value. AL anterolateral, AM anteromedial, SL superolateral, SM superomedial, PM posteromedial, PL posterolateral, M medial, L lateral, T0 initial timepoint, T1 middle timepoint; T2 final timepoint.
