Each knee was tested sequentially under 4 conditions: (1) anterior cruciate ligament intact, (2) anterior cruciate ligament deficient, (3) single-bundle anterior cruciate ligament reconstruction using quadrupled hamstring tendon, and (4) single-tunnel\u2014double-bundle anterior cruciate ligament reconstruction using the same tunnels and quadrupled hamstring tendon graft as in the single-bundle anterior cruciate ligament reconstruction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Single-tunnel\u2014double-bundle anterior cruciate ligament reconstruction more closely restored the intact knee kinematics than single-bundle anterior cruciate ligament reconstruction at low flexion angles (\u226430\u00b0) under the anterior tibial load and simulated muscle load (P &lt; .05). However, single-tunnel\u2014double-bundle anterior cruciate ligament reconstruction overconstrained the knee joint at high flexion angles (\u226560\u00b0) under the anterior tibial load and at 0\u00b0
