Anterior cruciate ligament (ACL) tears are among the most common sports injuries. Numerous studies have shown that reduced hip rotation may play a role in ACL tears. The same question may also arise for hip injuries such as femoroacetabular impingement (FAI).
This research is based on the hypothesis that there is a relationship between FAI and ACL injury. In this context, 3D MRI of the hip would provide morphological details of the hip that are not currently available with other imaging techniques, thereby enabling early identification of FAI. This is the reason why this research has been initiated.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

FAI arm involves patients with ACL rupture. A 3D MRI scan of both hips of theses patients will be performed.
Other: 3D MRI
Intervention consists of performing a 3D MRI scan of both hips using a T1 sequence.
FAI (femoroacetabular impingement) prevalence
Prevalence of femoroacetabular impingement will be expressed as %. It will be measured on the injured knee side (i.e., ACL rupture) and on the healthy knee side (i.e., uninjured).
Time frame: Day 1
