RecruitingBehavioural interventionACL Reconstruction Rehabilitation With Exercise and Psychological SupportThe purpose of this study is to examine ACLR Rehabilitation with Exercise and Psychological Support (REPS), comparing two approaches for providing psychological support along with exercise during ACL reconstruction rehabilitation. In one group, physical therapists have received training that may boost emotional support during rehabilitation. In the other group, physical therapists will not have the training. Both groups will get similar exercises and participate in the same testing. Both groups will also watch short videos during rehabilitation that are specific to their group. Participants will not know to which group they are assigned until the end of the study. Participation will attend a total of four study visits over the course of 6 months, including 1 visit before the surgery and 3 visits during follow-up.
