Two-dimensional and three-dimensional biomechanical factors during 90° change of direction are associated to non-contact ACL injury in female soccer players
Key Points
- 2D video-analysis offers predictive insights in analyzing non-contact anterior cruciate ligament (ACL) injury risk compared to 3D.

BACKGROUND & OBJECTIVE
The efficacy of 2D vs. 3D video-analysis to determine the risk of ACL injury has never been assessed. Previous research has shown that female footballers are at a higher risk of ACL injury than males and they are less responsive to targeted preventative interventions e.g. the FIFA 11+ program (1).
The purpose this study was to prospectively investigate the biomechanical predictors of ACL injury during a change of direction (COD) task in female football players using both gold standard 3D motion capture and a qualitative scoring system based on 2D video-analysis. The hypothesis was that both the 3D motion capture and the 2D scoring system would detect clinically relevant biomechanical differences between non-injured and ACL-injured players.
The efficacy of 2D vs. 3D video-analysis to determine the risk of ACL injury has never been assessed.
The analysis of pelvis and trunk frontal plane kinematics in 2D could effectively detect core imbalance during the COD task.
METHODS
- 16 female soccer players (age 21.4 ± 4.3) were enrolled.
