Injury to the anterior cruciate ligament (ACL) is a common injury among football players, especially nowadays. Soccer, as a contact and extremely dynamic sport, requires from the participants the ability to suddenly change the direction of movement, stop, slow down, accelerate, land and jump. These are all demanding motor skills and their constant repetition during a game as well as the accelerated rhythm in which they are performed leads to an increased risk of ACL injury. today's professional football turns footballers into modern gladiators where only the best and maximally physically fit survive, which leads to the majority of footballers going beyond their realistic capabilities and overloading their bodies. If you add to that insufficient time for recovery due to too frequent matches, all the prerequisites for an increased risk of injury are present. This paper will present the anatomy and biomechanics of the knee joint itself, the mechanism of ACL injury in soccer players, diagnostics, surgical and non-surgical treatment options, and finally rehabilitation itself with an emphasis on postoperative rehabilitation. The rehabilitation procedures will be divided into several phases and in each of them the goals that should be achieved and the ways in which they can be best achieved will be presented. In each of these phases, the goals are different, so the role of physiotherapy itself changes accordingly. The long duration and complexity of the rehabilitation itself puts the role of physiotherapy, especially therapeutic exercise, in the center of successful recovery, and this is what will be shown in this paper.
