Retrospective cohort study. The investigators evaluated the early, middle and long term effects of different surgical methods of anterior cruciate ligament reconstruction on knee function.
In the evaluation, the investigators focused on the differences between different age groups, different genders and different basic motor states, the differences between early reconstruction and non-early reconstruction, and the differences in clinical outcomes of different surgical methods.
Age 13-65 included. Only include isolated anterior cruciate ligament(ACL) rupture. Excluded revision surgery. Excluded bilateral ACL rupture. Excluded the contralateral ACL tear after surgery. 40 patients at least in each group.
