This study aims to address the rising incidence of ACL injuries, particularly among adolescents, by developing and implementing a comprehensive prevention program based on the evidence-based "ACL Prevention for ALL" framework recommended by ESSKA-ESMA. The project focuses on muscle strengthening, flexibility, coordination, proper movement techniques, and a multidisciplinary approach involving coaches, physiotherapists, and physicians. Through targeted exercise modules, education, and dynamic evaluation-including 2D motion analysis-the study seeks to reduce ACL injuries, enhance movement safety, and enable individualized training plans by identifying and correcting muscle and biomechanical imbalances.

ESSKA/ESMA 'ACL Prevention for All' methodology
Procedure/SurgeryA workshop led by a trained physiotherapist/strength and conditioning coach and conducted under medical supervision. Based on the ESSKA/ESMA 'ACL Prevention for All' methodology, a total of 12 exercise units lasting 5 minutes each will be included.
Peak knee abduction moment
The strongest predictor of ACL injury risk according to the 'ligament dominance theory' and also the most frequently reported as changed after an IPP (Injury Prevention Program). Advantage: Quantifiable, measurable using 3D analysis and force platforms, and sensitive to changes.
Peak knee flexion angle
According to the 'quadriceps dominance theory,' a low angle increases the risk of ACL injury. Meta-analyses show an increase in the angle after IPP. Advantage: Easily measurable and consistently monitored in the literature.
Dynamic knee valgus (DKV)
Dynamic valgus is often described as a key injury mechanism, although its measurement is more complex and less standardized. It can be supplemented with specific angles such as knee abduction angle at initial contact (IC) and medial knee displacement.
Peak hip flexion angle & hip flexion at initial contact
Lower flexion means higher vertical ground reaction force (vGRF) and lower force absorption, resulting in higher ACL load.
Vertical Ground Reaction Force (vGRF)
Higher vGRF at landing correlates with increased knee loading. The effect of IPP here is debatable, but it is relevant as a secondary parameter.
