3D MRI Assessment of Femoroacetabular Impingement in Patients With ACL Rupture - Exploratory Study (IMAHANCHE)

November 27, 2025 updated by: GCS Ramsay Santé pour l'Enseignement et la Recherche

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: FAI arm
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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
FAI (femoroacetabular impingement) prevalence
Time Frame: Day 1
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
