Brain Function after ACL Reconstruction

Injury-related fear after ACL reconstruction has been a barrier to returning to sport and is associated with risk of re-injury. Additionally, previous research has show people who who have ACL injury can have changes in brain function. In this study, we want to learn if injury-related fear is associated with brain function. *This study is a collaboration with the UNC Sports Medicine Institute*
