Étude des risques de lésion du ligament croisé antérieur chez la joueuse de sports pivot

Abstract : ACL injuries are severe and highly prevalent in female handball and basketball players. The increasing participation of women in multidirectional sports conduces to a better understand the mechanism and causes of the injury. The aim of this thesis is to investigate anterior cruciate ligament injury risk among female players in multidirectional sports and its workload-induced changes. The first part is a narrative review about the dynamic process of sports injury. Epidemiologic and biomechanic approaches were used to explain the complexity of risk factors and injury mechanism interaction. These data showed the key role of neuromuscular risk factors in building the incitative event of anterior cruciate ligament injuries. The lack of knowledge about the impact of an acute workload on those risk factors in female multidirectional sports needs to be addressed.The second part is an experimental report, including two prospective studies and a systematic review using muscular assessment, systematic tools for literature review and biomechanical analysis (kinetics, kinematics and laximetry). The results showed the specificity of female handball players when performing an isokinetic fatigue protocol. The jump landing kinetic was the most impacted by a fatigue protocol. Cutting techniques were the less impacted. The analysis of 766 side-step-cutting showed that knee joint loading is anticipated (46 to 48 ms after initial contact) in female handball and basketball players. It was also shown that women performed side-step-cutting with similar knee amplitude than the injury mechanism, a less flexed trunk position and a highest angle-velocity than men.The third part of this work proposes a discussion of those results in relation to their perspectives for the prevention of anterior cruciate ligament injury risk in female handball and basketball players.
