INTRODUCTION: The knee joint is the most complex joint in the human body and as such is most susceptible to injury. Anterior cruciate ligament injury increases the risk of developing both secondary injuries and a fear of returning to sports afterwards. PROCEDURES: 66 studies have been included in the writing of the thesis. Three of them are books and 63 have been downloaded from the online database and all literature corresponds to the content of the thesis. TOPIC REVIEW: Anterior cruciate ligament injury reduces an individual’s quality of life. Women are more often injured, and the mechanism of occurrence is sudden deceleration, hyperextension, or sudden joint rotation. The diagnostic test performed by a physiotherapist is the Lachman test. It is the gold standard due to its high sensitivity and specificity. A pivot shift test and an anterior drawer test can also be performed to confirm the diagnosis. Today, more and more research confirms the best diagnostic combination comprising the Lachman test and the Lever sign test due to its high specificity. Fear and anxiety that often occur after an injury have not only psychological consequences, but also a negative impact on physical performance after a successful rehabilitation process. CONCLUSION: Preventive programs with neuromuscular training in early adolescence reduce the risk of developing anterior cruciate ligament injury in the future. Maintaining knee health prevents the development of posttraumatic osteoarthritis and allows for a better quality of life. Neuromuscular and proprioceptive training have been shown to be the best interventions for the prevention and subsequent recovery from anterior cruciate ligament injury.
