title: In vitro comparison of over-the-top and through-the-condyle anterior cruciate ligament reconstructions.
abstract: Knee kinematics, during standard knee examination maneuvers, were measured on 15 fresh cadaveric knees in their normal state and after isolated sectioning of the anterior cruciate ligament using a six degree of freedom electrogoniometer. Proximal iliotibial band autografts were used to perform two anterior cruciate ligament reconstructions on the cadaveric knees: an over-the-top reconstruction and a through-the-condyle procedure. Both of these reconstructions reduced the abnormal anterior translation of the anterior cruciate ligament-deficient knee seen in Lachman testing. However, neither reconstruction restored the normal anterior translation. In addition, other motions remained uncorrected: 1) the internal rotation due to internal torque at full extension; 2) coupled anterior translation during internal rotation at full extension; and 3) coupled medial translation with anterior translation in Lachman testing. There were no statistical differences noted in the joint kinematics created by either reconstruction.
