Abstract
Purpose: Our primary goal was to deepen the understanding of the mechanisms leading to anterior cruciate ligament (ACL) injuries by reconstructing the three-dimensional (3D) joint kinematics of ACL injuries that occurred in professional male football matches. In particular, we aimed to compare the time courses of trunk and injured limb joint angles between noncontact and indirect contact injury mechanisms.
Methods: In this cross-sectional observational study, we analysed a total of 27 cases (18 noncontact, 9 indirect contact). Whole-body 3D kinematics preceding and during ACL injuries was reconstructed using the Model-Based Image-Matching technique, implemented in Blender. For each injury, television footage from multiple perspectives (≥2, nine frames per view) were used, and Euler's joint angles across all the anatomical planes were extracted. The joint angle time courses of both the trunk and the injured limb, comprising 12 waveforms in total, were compared between injury mechanisms and Statistical Parametric Mapping was used to detect significant clusters.
Results: Compared to noncontact injuries, indirect contact cases showed a lower hip abduction (-16°, p = 0.003), knee internal rotation (~3°, p < 0.001) at the initial contact with the ground, and ankle dorsiflexion (~7°, p = 0.035) at instants before the initial ground contact. These differences resulted from the player's adaptation to the sudden (yet variable) mechanical perturbation due to the contact with the opponent.
Conclusion: Mechanical interactions with other players impact segmental kinematics before and during ACL injuries in professional male football. These findings reinforce the importance of considering the sport-specificity of mechanisms in injury prevention.
期刊介绍：
Few other areas of orthopedic surgery and traumatology have undergone such a dramatic evolution in the last 10 years as knee surgery, arthroscopy and sports traumatology. Ranked among the top 33% of journals in both Orthopedics and Sports Sciences, the goal of this European journal is to publish papers about innovative knee surgery, sports trauma surgery and arthroscopy. Each issue features a series of peer-reviewed articles that deal with diagnosis and management and with basic research. Each issue also contains at least one review article about an important clinical problem. Case presentations or short notes about technical innovations are also accepted for publication.
The articles cover all aspects of knee surgery and all types of sports trauma; in addition, epidemiology, diagnosis, treatment and prevention, and all types of arthroscopy (not only the knee but also the shoulder, elbow, wrist, hip, ankle, etc.) are addressed. Articles on new diagnostic techniques such as MRI and ultrasound and high-quality articles about the biomechanics of joints, muscles and tendons are included. Although this is largely a clinical journal, it is also open to basic research with clinical relevance.
Because the journal is supported by a distinguished European Editorial Board, assisted by an international Advisory Board, you can be assured that the journal maintains the highest standards.
Official Clinical Journal of the European Society of Sports Traumatology, Knee Surgery and Arthroscopy (ESSKA).
