At present, whether patients with anterior cruciate ligament (ACL) injury can return to exercise lacks quantitative imaging indicators. In this study, ultra-short echo technique was used to evaluate the change of short T2 components like ligament in patients at chronic stage of ACL injury, finding that the proportion of short T2 componets (POS) in the overall signal can be used to reflect the extent of ACL injury and recovery. This study suggests that there are changes in the short-T2 components in patients with chronic ACL injury, and POS is superior to IKDC in assessing joint stability.
