Objective The purpose of this study was to observe the feature of tunnel enlargement after anterior cruciate ligament reconstructions and to investigate the influencing factors and the relationship between bone tunnel enlargement and clinical outcome. Methods There were 103 patients who accepted anterior cruciate ligament reconstructions with autogenous hamstring tendons for follow-up.
