Diagnosis & Tests
How is the injury recognized?
Diagnosis of an ACL injury begins with a history and physical exam. There are several tests to see whether the knee is unstable and moving abnormally. Sometimes fluid is taken from the joint with a needle to see if it is bloody. Joint X-rays usually show nothing except swelling. An MRI can show the torn ligament, joint swelling, and possibly other injuries.
