Normally it is 6-8 months...however one of my girls blew out all the ligaments in her knee and they said 8 months.
Another girl only tore her ACL and nothing else...the ACL just came unattached at the top of the bone and the doctor said she would be back kicking a ball in 6 weeks and to full strength in 4 months. Depends on the severity of the ACL tear and the other ligaments I believe.
