Abstrakt		Background. The anterior cruciate ligament has a complex fiber anatomy and is not considered to be a uniform structure. Current anterior cruciate ligament reconstructions succeed in stabilizing the knee, but they neither restore normal knee kinematics nor reproduce normal ligament function. Loosening or rupture of the graft, degenrative changes and false function of the knee may result. To improve the outcome of the reocnstruction, it may be necessary to incorporate the complex function of intact anterior cruciate ligament into the replacement graft. We think, that biomechanics of the graft can be influenced by position and orientation of the attachment sites. In this work, original methodology for the study of three-dimensional biomechanics on a graphical model of the knee is presented. Biomechanics of the anterior cruciate ligament was compared to biomechanics of the grafts on computer simulated reconstructions. Results were verified on a cadaveric study. Methods. Kinematic and geometrical data graphical model of the knee were gathered by coordinate measuring machine from fresh frozen and then slowly thawer cadaveric knee, fixed in a support mechanism, that allowed six degrees of freedom of motion in the knee joint. A three-dimensional computer model of the knee joint was constructed by the use of I-DEAS Master Series V.1.3. (SDRC) software. Anterior cruciate ligament and grafts were modeled. the isometry of ACL and PCL fibres during flexion and extension of the knee was studied by determining the distances between the insertion points of individual fibres on the femur and tibia respectively. Isometry pattern of the fibres of the anterior cruciate ligament and the graft in various positions and orientations of femoral attachment site was determined.
