The goal of this clinical trial is to to determine the extent of the association between objective changes in the muscle function of the knee extensors (strength and power) and the function reported by the patient following ACL reconstruction surgery. The main questions it aims to answer is: \- Pre- and post-operative (6 months) changes in maximum knee extensor strength following ACL reconstruction, correlated with the IKDC-SKF score.
Before surgery : * The patient will undergo a series of assessment tests, including: * An assessment of the force-velocity and power-velocity relationships for each leg during a cycling task * An assessment of unilateral force-velocity and power-velocity relationships during a knee extension task * An assessment of maximum strength and explosive strength in isometric (static) mode of the knee extensors. * A questionnaire-based assessment of IKDC-SKF scores. Evaluations will be repeated at 3 and 6 month after surgery ; Patients will be monitored for up to 24 months following their surgery
Inclusion Criteria: * Patients requiring isolated or complex ACL reconstruction (combined with a meniscal injury) * Patients who are physically active (Tegner score ≥ 4) and wish to resume such activity. * Patients with no history of surgery on the ipsilateral knee (i.e., native knee). * Patients able to comply with the study procedures * Patients who have given their free and informed written consent, having been informed of the purpose of the study, its procedure and its risks. * Be affiliated to a social security scheme.
Exclusion Criteria: * Patient with comprehension difficulties * Recurrent rupture of the ipsilateral ACL * Multi-ligament injuries (i.e., injury to the medial collateral ligament, lateral collateral ligament or posterior cruciate ligament)
