Background
Anterior cruciate ligament (ACL) injury is a common indication for sports-related major surgery and accounts for a large proportion of ligamentous injuries in athletes. The advancements in 2D and 3D MRI have provided considerable potential for a one-stop shop radiation-free assessment with an all-in-one modality examination of the knee, for both soft-tissue and bone evaluations. This article reviews ACL injuries and types of surgical managements with illustrative examples using high resolution 2D and 3D MRI. Various complications of ACL reconstruction procedures are highlighted with a focus on the use of advanced MRI and relevant arthroscopic correlations.

Educational Goals / Teaching Points
The goals of this exhibit are to understand mechanisms of ACL injury and associated injuries; review types of grafts and advantages and disadvantages; review normal postoperative appearance of graft reconstruction; and review postoperative complications

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
This exhibit includes a review of ACL anatomical landmarks, ACL graft accurate placement, and 3D MRI capabilities.

Conclusion
Owing to the high incidence of injuries requiring ACL surgeries and their substantial societal and economic impacts, it is imperative to be familiar with normal and abnormal MR imaging appearances of ACL injuries as well as their findings in normal and abnormal postoperative status. New developments in the field of 3D MRI continue to push the envelope in the field of diagnostics, aiding high-resolution visualization of the complications in greater anatomic detail and accuracy, which may help timely planning and management of such patients.
