Overview
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.
Detailed description
Anterior cruciate ligament (ACL) tears are among the most common sports injuries. It is estimated that approximately 150,000 ACL reconstructions are performed each year in the United States. 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.
Interventions
- Other 3D MRI
Intervention consists of performing a 3D MRI scan of both hips using a T1 sequence.
Primary outcome measures
- FAI (femoroacetabular impingement) prevalence [Time frame: Day 1]
