Inclusion criteria

Inclusion criteria: Inclusion criteria for patients consisted of an age between 14 and 55 years, ACL reconstruction with an autologous ipsilateral quadrupled hamstring graft (STGT), complete preoperative MRI data set of the injured knee joint and an intraoperative documented graft diameter.
