Auch wenn gewiss meist nicht ein einzelner Einflussfaktor zu einem vorderem Kreuzbandriss im Fußballspiel führt, sondern es vielmehr ein Zusammenspiel mehrerer Faktoren ist, die die Verletzung bedingen, zeigten sich in unserer Untersuchung erwähnenswerte Auffälligkeiten. So konnten wir zusammenfassend feststellen, dass insbesondere jegliche Belastungs- und Intensitätssteigerung, wie beispielsweise eine erhöhte Spiel- und Trainingsfrequenz in der Vorbereitungsphase oder der Übergang vom Jugend- zum Erwachsenenfußball, zu einer erhöhten VKB-Rupturrate im Fußball führt.

Introduction:
The rupture of the anterior cruciate ligament is a serious, common, and costly health care injury. The incidence of ruptures of the anterior cruciate ligament in football in men is given between 0.063 and 0.150 per 1000 hours. In women it is about three times higher. The primary aim of our study was to use a questionnaire to investigate the influencing and risk factors for suffering an anterior cruciate ligament rupture during a soccer game.
Material and methods:
This epidemiological investigation is a retrospective analysis. The data was collected using a questionnaire. There were questions about epidemiological data, the mechanism of injury and extrinsic risk factors. The analyzes includes only acl-injuries sustained by playing soccer in training or match situation.
Results:
A total of 590 patients were collected during the course of the study. These included 28 women and 562 men. The mean age of the patients at the time of injury was 23.92 years (SD: ± 7.44). The average training time per week was 5.49 hours (SD: ± 3.48). 23.1 percent (n = 136) stated that they had previously felt complaints or injuries. ACL ruptures occurred more frequently in the preparation phase and on the first match days. If you summarize the first four game days of a season and the previous preparatory phase, 53.1 percent (n = 259) of ACL ruptures occurred during this period. Almost half of the players were injured within the first thirty minutes (n = 196; 47.2%), which was followed by a significant drop in the number of ruptures at the end of the first half and towards the end of the game. Around two-thirds of the players (65%; n = 382) tore their anterior cruciate ligament without contact with an opponent, whereas only around one-third of the players (35%; n = 206) were in contact with an opponent or teammate at the time of the injury. When asked whether the injured knee joint was the shooting leg or the standing leg, 329 (56.3%) players stated that they had sustained the injury on the shooting leg.
Conclusion:
Even if it is certainly not a single influencing factor that usually leads to an anterior cruciate ligament tear, but rather a combination of several factors that cause the injury, our investigation revealed noteworthy abnormalities. In summary, we were able to determine that any increase in stress and intensity, such as an increased frequency of games and training in the preparation phase or the transition from youth to adult football, leads to an increased ACL rupture rate.
