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.
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
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)
Single group
assessment
Other intervention* Assessment of force-velocity and power-velocity relationships in each leg during a cycling task * Assessment of unilateral force-velocity and power-velocity relationships during a knee extension task * Assessment of maximum force and explosive force in isometric (static) conditions of the knee extensors. * Measurement of scores using questionnaires (IKDC-SKF).
Correlation of maximum knee extension strength to IKDC-SKF scores
Relationship (r coefficient) between 0-6 month delta of maximum knee extension strength measurements and International Knee Documentation Commitee-SKF scores (100: no limitation)
Peri-operatory trajectory of maximal dynamic force
Trajectory of evolution of F0 (maximal dynamic force) between baseline, 3 and 6 months, compared between legs (linear mixed effect model).
Peri-operatory trajectory of maximal contraction velocity
Trajectory of evolution of V0 (maximal contraction velocity) between baseline, 3 and 6 months, compared between legs (linear mixed effect model).
Peri-operatory trajectory of rate of force development
Trajectory of evolution of rate of force development between baseline, 3 and 6 months, compared between legs (linear mixed effect model).
Peri-operatory trajectory of maximal isometric force
Trajectory of evolution of maximal isometric force (Fmax) between baseline, 3 and 6 months, compared between legs (linear mixed effect model).
