353 SUMMARY Objective. Epidemiological studies on soccer injuries show that anterior cruciate ligament, groin, and hamstring injuries are heavily impacting availability, therefore medical research has focused on them. A certain number of studies have focused on the possible association between these three injuries. The aim of this study is to describe the possible association between these three injuries and to discuss their possible logical association. Methods. This study is based on the injury records of four international Qatar league players who suffered all these three injuries during their career. Our hypothesis is that these three injuries are related to each other through a cause-effect mechanism. Results. Based on the observational data of this study, the hypothesis that the anterior cruciate ligament, groin and hamstring injuries may be associated with each other can be advanced. This hypothesis is based on both anatomical and functional justifications. Conclusions. Being our knowledge of the pathophysiology and factors predisposing athletes to muscle, tendon and articular injury is still limited, the consequences of another type of injury on the athlete’s overall injury risk profile have probably been underestimated or not correctly understood. Further studies are necessary to clarify this cause-effect relation and this study also represents a call for action for future researches in this area.
