Anthropometric measurements have been associated with anterior cruciate ligament (ACL) injury in women. PURPOSE Assess the association between anthropometric measures of the lower extremities and dynamic knee valgus in women with and without ACL reconstruction. METHODS Twenty‐nine women (non‐injured=15, ACL=14) participated in this investigation. Anthropometric measures included: height, weight, inter‐ASIS distance, ASIS‐to‐trochanter distance, leg length, knee width, and ankle width. Dynamic knee valgus was measured with a three‐dimensional motion capture system (120Hz) as the distance between markers placed at the lateral femoral epicondyles during the landing phase of a double‐legged 60‐cm height drop jump. T‐tests were used to compare anthropometric measures between groups. Multiple linear regressions were used to examine the association between anthropometric variables and valgus. RESULTS All measurements except knee width were statistically significant different (p>.05) between groups with the ACL group exhibiting greater values. Regression analyses showed no statistically significant association for the control group (r 2 =.51; p>.05), whilst the association for the ACL group was statistically significant (r 2 =.89; p=.007). CONCLUSIONS It appears that anthropometric measures are predisposing factors to dynamic knee valgus that in turn are directly related to ACL injury.
