BACKGROUND Successful anterior cruciate ligament reconstruction with use of soft-tissue grafts requires healing between tendon and bone. Little is known about the effect of mechanical load on the cellular and molecular cascade of tendon-to-bone healing. Understanding these mechanical influences has critical implications for postoperative rehabilitation following anterior cruciate ligament recon...

BACKGROUND The mechanism for noncontact anterior cruciate ligament injury is still a matter of controversy. Video analysis of injury tapes is the only method available to extract biomechanical information from actual anterior cruciate ligament injury cases. PURPOSE This article describes 3-dimensional knee joint kinematics in anterior cruciate ligament injury situations using a model-based im...

On the basis of earlier reported data on the in vitro kinematics of passive knee-joint motions of four knee specimens, the length changes of ligament fiber bundles were determined by using the points of insertion on the tibia and femur. The kinematic data and the insertions of the ligaments were obtained by using Roentgenstereophotogrammetry. Different fiber bundles of the anterior and posterio...

Objectives: This study aimed to spotlight on the diagnostic value of magnetic resonance imaging (MRI) in assessment anterior cruciate ligament (ACL) reconstruction graft & detection its complications.

A biore actor for the mechanical stimulation of silk based scaffolds has been developed. The bi oreactor simulates the natural movement of the anterior cruciate ligament by applying a biaxial movement on the scaffold. The silk scaffolds are prepared in a way that mimicks the mechanical properties (strength, stiffness) of natural anterior cruciate ligaments. The influence of degumming on the mec...

A prospective study was undertaken to compare the accuracy of the Lachman test, anterior drawer test and jerk test with the KT1000 knee arthrometer in patients with proven anterior cruciate ligament deficiency. The Lachman and anterior drawer tests were found to be the most accurate indicators of anterior cruciate ligament deficiency. The KT1000 knee arthrometer was found to be totally inaccura...

BACKGROUND Although previous studies suggested that female patients are predisposed to increase graft laxity compared with male patients after single-bundle anterior cruciate ligament reconstruction using autogenous hamstring tendons, there have been no studies specifically examining gender-based differences in outcome after anatomic double-bundle anterior cruciate ligament reconstruction with ...

In this paper a new navigation system, KIN-Nav, developed for research and used during 80 anterior cruciate ligament (ACL) reconstructions is described. KIN-Nav is a user-friendly navigation system for flexible intraoperative acquisitions of anatomical and kinematic data, suitable for validation of biomechanical hypotheses. It performs real-time quantitative evaluation of antero-posterior, inte...
