Brief summary
Knees injuries commonly affect the ACL. French current methodology is based on MRI focused on the knee with morphological sequences (T1, DP fat sat) allowing the study of ACL as follows: No lesion / Partial tear / Complete tear. The treatment (kinesitherapy, surgery, no intervention) is defined taking into account several factors such as age, knee laxity, physical activity and outcome of the radiology analysis (partial or complete tear). However, if the classification is straightforward in case of complete tear, it is not possible to establish a quantitative impact on the ACL in case of partial tear. As a consequence, the investigators will analyze the anisotropy coefficient with diffusion tractography. Any patient who undergo a posttraumatic knee MRI at the CHU Amiens Picardie will have an appointment at the 3T "Signa" MRI that has the knee-centric diffusion tractography sequence.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Anisotropy score after tractography MRI sequence | one day | Anisotropy coefficient value is between 0 (isotropic medium) to 1 (fibrillar medium) . Anisotropy coefficient =0 is for total ACL rupture Anisotropy coefficient between 0 end 0.8 is for partial ACL rupture |
| Correlation between anisotropy coefficient and ACL lesion state | one year | Anisotropy coefficient value is between 0 (isotropic medium) to 1 (fibrillar medium) . Anisotropy coefficient =0 is for total ACL rupture ACL lesion state are No lesion, Partial tear or Complete tear |
