About this study
Official title: Risk Factors for Cruciate Ligament Injuries
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.
Read the detailed description
Participants will be prospectively recruited at their first physiotherapist clinical session. On this occasion, participants will be asked to fill in a questionnaire regarding injury situation, game or training, sex, age, sport affiliation, level of sport, other aspects of sport such as participation in several teams and junior versus senior games/training. In addition, questions regarding previous injury will also be documented.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Total work load (time frame: Day 1). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Dec 2025.
