Asymmetric Lack of Knee Flexion as a Symptom of DLM in Children
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.

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 |
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. |

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 |
