Magnetic resonance imaging evaluation was performed in 53 patients (88%) (32 in double\u2010bundle group and 21 in single\u2010bundle group) for a mean of 27 months' follow\u2010up (range, 24 to 36 months). Tunnel enlargement was determined by digital measurement of the widths perpendicular to the long axis of the tunnels on an oblique coronal and sagittal plane. The magnetic resonance imaging measurements were compared with the intraoperative drill diameter.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      No significant differences were found between the double\u2010bundle group and the single\u2010bundle group in tunnel enlargement on the femoral side. However, on the tibial side, tunnel enlargement was greater in the single\u2010bundle group than in the double\u2010bundle group in each tunnel (\n                      <jats:italic>P<\/jats:italic>\n                      = .051). In all knees, tunnel enlargement both on the tibial side and on the femoral side correlated significantly with the anterior and rotational laxity of the operated knee. In the double\u2010bundle group, no tunnel communication between the anteromedial and posterolateral tunnels was seen in any of the patients on either the tibial side or femoral side.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This prospective, randomized study showed that our double\u2010bundle ACL reconstruction technique results in less tunnel enlargement in each tunnel on the tibial side than the single\u2010bundle technique with similar fixation methods, graft material, and rehabilitation. In addition, no tunnel communication was observed in the patients undergoing double\u2010bundle ACL reconstruction. The clinical results were good in both groups. However, the patients who had more tunnel enlargement had significantly more anterior and rotational laxity of the operated knee as well.<\/jats:p>\n                  <\/jats:sec>\n
