Chiang, ER, et al. - In this study, 60 subjects were divided into 2 groups viz, bioabsorbable interference screw (BS) group and cortical button (CB) group and then, analyzed to examine the tunnel enlargement rate and clinical function by comparing double-bundle anterior cruciate ligament reconstruction (ACLR) using different fixation methods. They noticed greater tunnel enlargement and significantly increased rate of tunnel communication in the BS group as compared to the CB group. They also found a significant increase in enlargement of posterolateral (PL) tibial tunnel in the CB group. They observed no significant variation in postoperative functional outcomes between the 2 groups. Functional improvement in the Knee Injury and Osteoarthritis Outcome Score and International Knee Documentation Committee score was also noted in both the groups.
