Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This prospectively study aims to evaluate the evolution of knee joint proprioception on isokinetic dynamometer before and after Anterior Cruciate Ligament (ACL) reconstruction and its relationships with muscle strength, self reported questionnaire and return to sport. This study will include 30 athletes with isolated ACL rupture, and treated with ACL reconstruction surgery and 15 healthy volunteers.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Anterior cruciate ligament (ACL) rupture is a common injury in athletes. It has multiple consequences on the knee: instability, pain, loss of muscle strength, proprioceptive impairments, modification of the knee kinematics and premature knee osteoarthritis. In athletes, the majority of these injuries are treated with ACL reconstruction surgery. The main objective of this treatment is the reduction of knee instability to allow return to sport, and this at the same level prior to the injury. Thus, the athlete's follow-up after the surgery is essential to guide the return to sport and to ensure that the knee sensorimotor control allows the return to sport. Currently this assessment is based primarily on functional testings and measurement of muscle strength.

The investigators propose to prospectively study the evolution of instrumentally measured knee proprioception using isokinetic dynamometer before and after ACL reconstruction as well as a study of the factors associated with its favorable evolution and its impact in the return to sport and its level.
