Background: The knee is one of the complex joints in the human body and consists of several internal structures that may lead to the emergence of symptoms of knee injuries [1]. The anterior cruciate ligament, or ACL, is one of the major ligaments of the knee that is located in the middle of the knee and runs from the femur (thigh bone) to the tibia (shin bone). It prevents the tibia from sliding out in front of the femur. Together with posterior cruciate ligament (PCL) it provides rotational stability to the knee [2]. In the case of ACL injuries of the knee, magnetic resonance imaging (MRI) is used to diagnose the affected knee. From this point of view, this study aims to identify the sites of ACL tears and evaluate the role of magnetic resonance imaging (MRI) in the diagnosis of Anterior Cruciate Ligament (ACL) tears. Materials and Methods: This study was conducted at the Department of Radiological Diagnostics of Medical Services, Abu Dhabi Police, United Arab Emirates. After getting the institutional approval, the study sample was selected from those with knee injuries. Socio-demographic information about these patients such as gender, age, etc. was recorded. The study sample included 150 patients (113 males and 37 females), their ages ranged between 17 and 52 years, with a mean age of 25 years, and all the patients underwent an initial diagnosis of anterior cruciate ligament injuries. MRI of the knee joint was performed for all cases using different MRI techniques. Results: MRI results confirmed that among the 155 patients, 68% had an ACL tear (89.33% complete tear, 10.67% partial tear), while 32% had no ACL tear. Also, the prevalence of the location of an ACL tear distributed in the femoral end of the knee (62%), the mid third of the knee (14%) and the tibial end (23%). Conclusion: MRI findings have proven to be more effective in assessing complete ACL tear, while the assessment of partial tear requires the use of more developed MRI techniques. All cases of ....
