The purpose of this study is to compare changes in lower limb symmetry during functional and strength tests, before and after the motor imagery program, in patients who received the 3-week motor imagery program starting 3 months post-surgery versus patients who did not receive the motor imagery program.

This is a prospective, comparative, randomized, controlled, single-blind (patient), single-center study evaluating the effects of a motor imagery program in parallel with rehabilitation sessions in patients who have had an anterior cruciate ligament rupture.

The study population is composed of adult patients who underwent reconstructive surgery after anterior cruciate ligament rupture, followed up at the Clinique de la Sauvegarde in Lyon for post-operative functional and strength testing of the anterior cruciate ligament.

Patients included in the study will be randomized into two study arms (experimental arm and control arm).

Inclusion Criteria:

• Patients aged 18 to 45;
• Individuals who have undergone anterior cruciate ligament reconstruction for the first time on the operated leg;
• All types of surgery (harvesting of the new gracilis or patellar tendon) within 3 months prior to inclusion;
• Patients able to understand and read French;
• Affiliation with a social insurance plan;
• Signed informed consent.

Exclusion Criteria:

• Recurrence or rupture of the contralateral anterior cruciate ligament;
• Osteotomy;
• Cognitive disorders observed by the investigator;
• Vestibular disorders known to the patient or observed by the investigator;
• Post-surgical complications (infection, early graft rupture);
• Patient participating in another interventional clinical trial, or in a period of exclusion from another interventional study;
• Patient under guardianship or conservatorship;
• Pregnant or breastfeeding women.
