To detect an ACL injury, doctors examine the knee for range of motion, swelling, stability and ligament integrity, and assess lower body strength. X-rays may be used to check for injuries to bone, and an MRI scan can help with assessing the injury's severity and detecting associated problems, such as sprains of other knee ligaments, meniscus tears or articular cartilage damage.
