An Anterior Cruciate Ligament tear is common among knee injuries. The ACL is a weaker ligament then the other internal knee ligament Posterior Cruciate Ligament. This MRI image is utilizing a PD weighted sequence in the sagittal view and demonstrates a missing ACL. This patient was a 14 year old male and suffered a sport injury. I am very familiar with this type of injury because I too suffered an ACL tear during a football game. I can tell you he has a long recovery time if he chooses to have surgery to reconstruct his ACL. It probably took me a year before I felt 100 percent.
