| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Lack of knee flexion | During preoperative clinical exam, highlight of a lack of knee flexion. The lack of knee flexion consists in an asymmetric heel-bottom distance or an asymmetric goniometric measure of knee flexion. All others characteristics are also analyzed like in group 2, as : rest of knee motion, MRI meniscus shift, arthroscopic shift |
| |
| Full knee flexion | During preoperative clinical exam, highlight of a lack of knee flexion. The lack of knee flexion consists in an asymmetric heel-bottom distance or an asymmetric goniometric measure of knee flexion. Patients in group 2 don't have any asymmetric full knee flexion. All others characteristics are also analyzed like in group 2, as : rest of knee motion, MRI meniscus shift, arthroscopic shift |

|---|---|---|---|---|
| Find a link between lack of knee flexion and meniscal posterior luxation fixed | Diagnostic Test | Measure the full flexion angle of the knee using a goniometer. Measure the heel-buttom distance. All measurements are carried out in bilateral and comparative ways. Search for the meniscal position on MRI and intraoperatively: no shift, anterior, medial, posterior shift. |
| Measure | Description | Time Frame |
|---|---|---|
| Meniscal posterior shift per-operative | Visualization of a dislocated posterior meniscus during arthroscopy, before any reduction or meniscoplasty procedure | During surgery for MCA-type DLM |
