After an ACL surgery many people worry that they have reinjured their ACL or torn their ACL graft. If you are worried about this know that it is a very common concern. You have gone through a stressful surgery and likely experienced significant pain and limitaiton in your movement. In your mind the worse thing would be if you injured the ACL graft and you now have to go through all of that again! Many people worry that simple activities such as bending and straightening their knee after surgery can damage the ACL. Others worry that simply by putting weight on their leg they may have damaged their ACL graft. These activities do not result in an ACL graft tear. In this video, Lauren Youssef, a physical therapy student from the University of Toronto, explains why retearing your ACL graft after surgery with normal movements and you recovery exercises is unlikely. If you would also like to learn about the ACL recovery timeline we have a great blog about that topic here.
