Figure 1. Example of results regarding the range of tibial rotation in both ACL injured knees (red lines) and ACL reconstructed knees (blue lines). The averages are depicted using the bold red and blue line respectively, The solid black lines represent the upper and lower limit of the range of rotation, in this example from the ACL injured knees.The Spearman’s correlation coefficients are displayed in Tables 3 and 4 respectively. Little (if any) to weak correlations were found between medial PTS, lateral PTS and Δ PTS and ATT for ACL-deficient or for ACL-reconstructed knees in all three dynamic tests. Little (if any) to weak correlations were found for ACL-deficient knees between medial PTS, lateral PTS, and ΔPTS and rTR in all three dynamic tests. In ACLreconstructed knees, these correlations were all moderate-to-strong, except for the correlations between lateral PTS and rTR during level walking and side jump (little (if any) correlation) and medial PTS and rTR during level walking (weak correlation).Mark Zee.indd 102 03-01-2024 08:56
