The mean follow\u2010up period is 33.7 months for the DB group, 31.9 months for the AM group, and 33.2 months for the PL group. We evaluated the Lysholm score, Tegner score, anterior laxity with the KT\u20101000 arthrometer (MEDmetric, San Diego, CA), rotator instability with the pivot\u2010shift test, and muscle strength with knee extensor and flexor isokinetic peak torques at 60\u00b0\/s.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      There were no significant differences in postoperative Lysholm score and Tegner score. Anterior stability of the knee, as measured by the KT\u20101000 arthrometer, was significantly better in the DB group than the PL group (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .05). The negative rate of the manual pivot\u2010shift test in the DB group was significantly superior to the PL group (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .05).

The DB and AM groups had greater flexion strength than the PL group. The DB and AM groups had a similar rate of negative pivot\u2010shift test results, whereas the PL group had fewer negative pivot\u2010shift test results than the DB group. There were no KT\u20101000 side\u2010to\u2010side differences between the DB and AM groups, whereas the DB group had better results than the PL group. Overall, the clinical outcome as measured by Lysholm and Tegner scores was not different between groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
