Brief Summary

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.

Conditions

Femoroacetabular Impingement

Keywords

Outcome Measures

Primary Outcomes (1)

• 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).

  Day 1

Study Arms (1)

FAI arm

EXPERIMENTAL

FAI arm involves patients with ACL rupture. A 3D MRI scan of both hips of theses patients will be performed.

Other: 3D MRI

Interventions

3D MRI OTHER

Intervention consists of performing a 3D MRI scan of both hips using a T1 sequence.
