You have suffered a total or partial injury to the anterior cruciate ligament (ACL) , this ligament takes an important part of the rotational stability of your knee.

​

   The question of the operation will certainly arise and will depend on your motivations and needs .

   

   A clear discussion with your orthopedic surgeon will give you the guidelines of the ins and outs of your decision.

​

   However, special rehabilitation care will often be necessary to help you regain confidence in your knee.

​

   Also, we know that preparation before the operation improves the success of postoperative rehabilitation; it will be need to propose a preoperative rehabilitation.

​

   The knee acts as an intermediate joint in a linking system of interdependent segments; thus an ACL injury is a lesion that affects only one leg but the problem is in both.

(BENJAMINSE 2018).

​

  Injury to the ACL can be considered a neurophysiological dysfunction and not just a musculoskeletal injury. (KAPRELI 2009)

​

   The purpose of the sports rehabilitation process is to be able to bring the patient to manage rapid movements and dynamis activities which are more problematic; the neuro-muscular system which analyzes the movements must not find itself in a situation of black out and under optimal.

​

    Rehabilitation serves to give the brain the capacity to create a program in order to modify the neuromuscular system and make it more efficient.

​

   The sports therapist must guide the patient to find efficient movement solutions by stimulating an adapted motor learning process of the central nervous system (DIGENEN 2019).

​

   Motor learning is a process followed by an individual during which he acquires new motor skills accompanied by an almost permanent change in performance in the function of training or experience (GOKELER 2019).

​

  The quality of rehabilitation is to find an " optimal challenge point" between a simple task which will give a good performance and a complex task which leads the patient into error , but also learning .
