Update : got cast removed yesterday. The bone didn’t heal back into place. The injury was actually called a tibial spine avulsion so the acl is attached to the piece of bone but that piece didn’t heal back to the tibia. Doctor said essentially I now don’t have a working acl. He said to do physio and see him again in 3 months. Some people are stable enough that its ok to live like that. This seems crazy to me! Going to try to see another specialist to see if acl surgery can be done now
