Lack of knee flexion

Description:

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

Treatment:

Diagnostic Test: Find a link between lack of knee flexion and meniscal posterior luxation fixed

Full knee flexion

Description:

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
