Outline of Final Research Achievements

The purpose of this study was to investigate longitudinal changes in knee proprioception and gait stability following anterior cruciate ligament (ACL) injury and reconstruction surgery. We found that ACL reconstruction surgery might influence the bilateral knee joint proprioception and cause gait instability in antero-posterior direction at 6-months postoperative, but these changes disappeared at 12-months postoperative. Therefore, we believe that we should not only focus on the reconstructed leg; the relation to the contralateral leg needs to be taken into account at the same time within 12 months following ACL reconstruction surgery.
