How is a knee ligament injury diagnosed?

In addition to a complete medical history and physical examination, diagnostic procedures for a knee ligament injury may include the following:

X-ray – A diagnostic test which uses invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs onto film.

Magnetic resonance imaging (MRI) – A diagnostic procedure that uses a combination of large magnets, radiofrequencies, and a computer to produce detailed images of organs and structures within the body; can often determine damage or disease in a surrounding ligament or muscle. This is the most accurate way of radiologically assessing knee ligament injuries and will often be ordered by your referring doctor.

Arthroscopy – A minimally-invasive diagnostic and treatment procedure used for conditions of a joint. This procedure uses a small, lighted, optic tube (arthroscope) which is inserted into the joint through a small incision in the joint. Images of the inside of the joint are projected onto a video screen to help your surgeon evaluate knee disorders.
