Three-dimensional motion analysis was used to measure tibial rotation and rotational knee moments in the pre- and postfatigue states, during a swinging maneuver on the weightbearing leg from a standing position with the knee in extension.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Tibial rotation of the single-bundle group significantly increased postfatigue (prefatigue 22\u00b0 \u00b1 10\u00b0 vs 29\u00b0 \u00b1 15\u00b0 postfatigue, P = .015). In contrast, the double-bundle group showed similar tibial rotation values pre- and postfatigue (16\u00b0 \u00b1 6\u00b0 vs 18\u00b0 \u00b1 4\u00b0, P = .22). The double-bundle group showed a trend toward decreased tibial rotation values pre- and post-fatigue compared with controls (22 \u00b1 4 and 23 \u00b1 4) ( P = .065 and .08, respectively). In the prefatigue state, rotational moments (N\u00b7mm\/Kg) of the single-bundle (339 \u00b1 148) and double-bundle (317 \u00b1 97) groups were significantly lower than that of controls (465 \u00b1 134) ( P = .05 and .03, respectively). In the postfatigue state, an increase was observed in rotational moments of the single-bundle (388 \u00b1 131) and double-bundle (408 \u00b1 187) groups compared with prefatigue values, whereas a decrease was noted in the control group (411 \u00b1 117).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Single-bundle ACL-reconstructed knees demonstrate a reduced ability to resist rotational loads under fatigue.
