Abstract

PURPOSE:

The objective of this study was to evaluate multiple morphological features on MR images in patients with and without ACL rupture to evaluate whether there are certain variables that confer a higher risk for an ACL rupture.

METHODS:

MRI measurements were taken from 45 subjects with ACL injury and 43 subjects without ACL injury, by two independent observers. The morphometrics were compared between ACL-injured and non-injured subjects, between men and women and for male and female subjects separately. A factor analysis was performed to determine whether any variables were related in the injured, non-injured, male or female groups.

RESULTS:

There were no significant differences in the overall population between the ACL-injured and non-injured group. Significant differences were found in bicondylar (P ≤ 0.001), medial condyle (P ≤ 0.001) and lateral condyle widths (P = 0.001) between men and women. In the male group, there were no significant differences between ACL-injured and non-injured subjects. In the female group, there was a significant difference in bicondylar (P = 0.002) and lateral condyle width (P = 0.002) between ACL-injured and non-injured subjects.

CONCLUSIONS:

There were gender-related differences in bony morphology between ACL-injured and non-injured subjects. The morphological features that were different between ACL-injured and non-injured subjects varied between male and female subjects.

LEVEL OF EVIDENCE:

Case-Control study, Level III.
