This study investigated if knee joint moments are related to the foot strike angle in preplanned and unplanned handball-specific sidestep cuts performed by n = 51 female handball players. Canonical correlation analysis (CCA) with the foot strike angle as predictor variable was performed on the knee joint moment vector field (Mxyz). Subsequently, post-hoc tests using CCA for moment couples and linear regression for individual moment components were performed. In both conditions, the foot strike angle was related to Mxyz. However, the relationship remains partially unexplained when the three-dimensionality of the moment vector remains unaccounted for, especially in the unplanned cut. Given the time periods in which correlations exist, the foot strike angle shows potential to reduce multi-plane knee loading associated with ACL injury.
