After single-bundle or double-bundle ACL reconstruction, anteroposterior laxity gradually increased under quadriceps muscle activation in ACL-reconstructed and ACL-intact knees. Comparable increases in anterior tibial translation were seen in reconstructed and intact knees in the results of this study.
Researchers prospectively collected data from 30 men who underwent ACL reconstruction, of whom 15 underwent single-bundle reconstruction and 15 underwent double-bundle reconstruction; 15 controls were also included in the study. Knee range of motion, Lachman, anterior drawer and pivot-shift test results were obtained, as well as IKDC, KOOS, Lysholm and Tegner scores.
