Conditions

Highlights a New Clinical Sign Which Point Out a Meniscus Posterior Luxation Because of a MCA-type DLM

Keywords

discoid lateral meniscus, children, instability, arthroscopy, repair, lack of flexion, flexion block knee

Brief summary

Highlighted during the clinical examination of a knee flexion asymmetry, and related to the intraoperative meniscal observations on DLM. Search for a link between asymmetric bending defect and posterior shift in MCA-type DLM. Analysis of all patients with symptomatic DLM.

Interventions

DIAGNOSTIC_TESTFind a link between lack of knee flexion and meniscal posterior luxation fixed

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.
