Kinematics and Laxity of the Knee Joint after Anterior Cruciate Ligament Reconstruction

Abstract

Kinematics of the anterior cruciate ligament injured knee did not change significantly after ligament reconstruction, but the functional results were satisfactory and knee laxity was diminished.

Effect of Femoral Tunnel Placement for Reconstruction of the Anterior Cruciate Ligament on Tibial Rotation

“…In vivo studies with three-dimensional motion analysis from our laboratory [4][5][6] have demonstrated abnormal rotational knee movement during highly demanding activities after reconstruction of the anterior cruciate ligament. Our results have been verified by both in vitro and in vivo studies from other laboratories 2,7,[11][12][13][14] . Furthermore, authors of in vitro studies have examined the possible causes of this phenomenon and have investigated the effects, on rotational knee kinematics, of the configuration and placement of the graft used to reconstruct the anterior cruciate ligament.…”

“…This parameter is measured clinically with the Lachman test or the anterior drawer test 1 . However, rotational knee movement after injury and reconstruction of the anterior cruciate ligament is difficult to quantify [2][3][4][5][6][7] . The only clinical test for examining rotation is the pivot-shift test, which is a subjective static measurement that can mask small rotational differences between the intact and the reconstructed knee.…”

“…The only clinical test for examining rotation is the pivot-shift test, which is a subjective static measurement that can mask small rotational differences between the intact and the reconstructed knee. Thus, various researchers have assessed dynamic knee movement during activities of daily living in order to quantify rotation following reconstruction of the anterior cruciate ligament [2][3][4][5][6][7] . Such assessments are crucial because it has been reported recently that abnormal rotational movements of knees treated with reconstruction of the anteDisclosure: In support of their research for or preparation of this work, one or more of the authors received, in any one year, outside funding or grants of less than $10,000 from the Hellenic Association of Orthopaedic Surgery and Traumatology (HAOST-EEXOT).…”

Can Joint Contact Dynamics Be Restored by Anterior Cruciate Ligament Reconstruction?

“…Abnormal knee rotation occurs after ACL injury and is not corrected by conventional single-bundle (SB) ACL reconstruction [1,8,13,15,29,30,32,33]. Abnormal knee kinematics (translations, rotations) has been implicated in the initiation and progression of knee osteoarthritis secondary to altered normal joint contact [5].…”

“…Even with modern reconstruction techniques, it has not yet proven possible to demonstrate a lower incidence of OA in operated individuals (25,26) .…”
