About

The goal of this interventional study is to measure medial vastus inhibition and associate it with AMI classification in patients with ACL rupture. The main question it aims to answer is:

Is there a correlation between AMI classification and clinical assessment after ACL rupture ? Participants will undergo surface EMG and Myotonometry.

Enrollment: 90 estimated patients

Sex: All

Ages: 18 to 44 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patient, male or female, aged ≥ 18 years and < 45 years
• Patient with an ACL rupture confirmed by MRI
• Patient with an ACL rupture ≤ 30 days old
• French speaking patient who does not object to the use of his/her data

Exclusion criteria

• Patient with previous ipsi or contralateral knee injury/surgery
• Patient with multi-ligament injury
• Pregnant or breastfeeding woman

90 participants in 1 patient group

AMI testing group

Experimental group

Description:

Interventions administered are the following : * Surface EMG to measure inhibition of the VM and the RF on the injured and non-injured sides during attempts at voluntary contractions of the knee extensor muscles. * Myotonometry to measure the stiffness of the semi-membranosus and biceps femoris (long head) on the injured and non-injured sides under resting conditions

Treatment:

Other: Clinical testing
