Operation Korsband

This study aims to investigate if a detailed and comprehensive survey can identify, explain and prevent the risk factors for ACL injury.

A a new questionnaire has been developed with questions to young athletes who have suffered an anterior cruciate ligament injury. The questionnaire is more detailed and provide more information about how the anterior cruciate ligament injury occurred compared with the questionnaires currently available in the literature. This careful documentation will provide new knowledge and might be used to identify, explain and prevent risk factors that cause young athletes to suffer an anterior cruciate ligament injury.
