Introduction: Anterior cruciate ligament (ACL) injuries sustained in sports or recreational activities are frequent worldwide and have a substantial financial impact on society as a result of lost productivity and increased medical expenses. In the case of an ACL ligament injury to the knee, physiotherapy is crucial. Rehabilitating patients as soon as the inflammation has decreased is crucial. The protocols for ACL rehabilitation differ widely, and practitioners cannot agree on much of anything. Over the past ten years, however, there has been a consensus to move away from conservative, standardized length protocols and towards more individualized, accelerated protocols that adjust in length and modalities in accordance with patient preferences and specific findings. Aim of the Study: With an emphasis on cutting-edge techniques to address the unique needs of ACL-injured patients, this review outlines the most recent trends, viewpoints, and modalities in ACL rehabilitation research. Methodology:The review is a comprehensive research of PUBMED since the year 2001 to 2023. Conclusion:The new modalities being used in rehabilitation are accelerating patient recovery, and the approach has become more and more patient-dependent. For many ACL patients, reinstated in sports is a crucial factor, and psychological support is crucial to recovery. The most important component of the patient's care and management is physiotherapy. Physiotherapy plays a major role in managing patients both before and after ACL reconstruction and has a considerable impact on preventing ACL injuries.
