Overview
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.
Interventions
- Other Clinical testing
Intervention includes : * Surface EMG to measure inhibition of the VM and the rectus femoris (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 semimembranosus and biceps femoris (long head) on the injured and non-injured sides under resting conditions
Primary outcome measures
- Muscle Surface EMG and AMI correlation [Time frame: From enrollment to Day 30]
