Available in PDF, EPUB and Kindle. Book excerpt: Because of the role of the ACL in knee joint's biomechanics, it is essential to quantify the kinematics of ACL deficient and ACL reconstructed knee. In-vitro models bare the handicap of limited muscle simulation, while static, one-dimensional testing cannot predict the behavior of these groups of patients under realistic loading conditions. Currently, the most widely accepted method for assessing joint movement patterns is gait analysis. Respectively, 3D motion analysis is necessary to provide high reliability movement analysis. The purpose of the study was in-vivo evaluation of the behavior of the anterior cruciate ligament deficient (ACLD) and anterior cruciate ligament reconstructed (ACLR) knees during walking, using 3D, real-time assessment tool. Significant alterations of joint kinematics in the ACLD knee were revealed in this study by manifesting a higher flexion gait strategy and excessive internal tibial rotation during walking that could result in a more rapid cartilage thinning throughout the knee. In the other hand, even though ACLR knees showed some improvements in sagittal plane compared to ACLD knees, in axial plane there still exists difference compared to healthy control knees. These kinematic changes could lead to abnormal loading in knee joint and initiate the process for future chondral degeneration. However, the post-operative kinematic data were collected 10 months after surgery, so a longer follow-up is needed to evaluate if these kinematic changes persist in time, and their effects in joint degeneration.
