The knee is the largest joint in the human body. It plays a crucial role in a multitude of movements such as walking, jumping, squatting, and kneeling. Additionally, it enables us to accelerate, decelerate, spring off, and come to a stop. Due to its intricate structure, the knee is susceptible to various injuries. An anterior cruciate ligament (ACL) injury is one of the most common sports injuries, with potentially far-reaching implications for individuals, both physically and emotionally. The knee, being one of the most vital and complex joints in the body, is fundamental in providing stability and mobility, and an ACL injury can considerably impair its function. In this study, we thoroughly examined the process of graft selection for ACL reconstruction, considering the advantages and disadvantages of different graft types. After surgery, post-operative rehabilitation becomes paramount for a successful recovery. Beyond standard strengthening and mobility exercises, a range of specific exercises aimed at restoring the knee's functional capability and strength are presented. Re-injury prevention, especially upon returning to the field, is crucial. The psychological aspects of returning to play are often overlooked but are of utmost importance. In conclusion, this paper offers a comprehensive understanding of the challenges and solutions related to ACL injury, from the moment of injury to the time an athlete steps back onto the field.
