ABSTRACT
There are many injuries that are clinically challenging musculoskeletal disorders in emergency department patients. One of those is an anterior cruciate ligament (ACL) injury. Injuries to the ACL are among the most common injuries incurred to the knee in sports. ACL tears in children and adolescents are becoming more common as participation in formalized sports increases. This injury typically occurs with trauma to the knee. The purpose of this article is to discuss the assessment and management of patients with ACL injuries using an actual case presentation. It is imperative for the healthcare provider to appropriately assess and manage the patient with an ACL injury promptly to ensure that outcome is improved. Failure to recognize the severity of the problem may lead to increased morbidity with poor functional outcomes.
