“…Visual analysis of the lateral radiographs of the flexion series in the prosthetic knees suggested that the contact point between the femoral condyles and the tibial plateau did not move backwards during flexion, as was observed in the normal knees, but was located centrally or even slightly anteriorly (Soudry et al 1986), suggesting that no "roll-back" occurred.…”

“…Soudry M, Walker PS, Reilly DT, Kurosawa H. [16] showed that cruciate resection increases the shear forces and the rokking moments to the tibial components and that additional fixation means may be necessary to compensate. On the other hand, cruciate retention with low conformity gives higher contact forces, which may lead to more wear in the long term.…”

In this paper, we are presenting the results of the research based on dynamic simulation of human knee virtual model.Starting from the parts realized with computer tomography help, there were realized virtual models for the femur, tibia, meniscus and ligaments that form the complex human knee joint, and their discretisation in finites elements.There were raised tension and deformation diagrams for the meniscus subjected to different stresses. There are presented comparative diagrams for tensions, deformations and deforming energy for the normal meniscus, and, respectively, for the totally cut meniscus, with a third of the volume, or two thirds of the volume.There were raised diagrams of the cinematic parameters (positions, speeds, accelerations) of the femur -lateral meniscus couple. Virtual models of the bony structures were subjected to different cinematic and dynamic simulations, separately, or in whole the human knee joint. Maps of tension were presented for the whole joint and for its components, to different movement moments.

“…8,9,17,18 If the PCL is resected substitution with a posterior-stabilised (PS) design may be carried out but translation and gait may not be restored. 5,8,9 We compared the kinetics of a concave with those of a PS insert one year after operation using radiostereometry to determine whether the use of a PS design with a central post results in less translation and rotation.…”

We studied the kinetics of the knee in 20 patients (22 knees) 12 months after total knee arthroplasty (TKA), by using three-dimensional radiostereometry and film-exchanger techniques. Eleven knees had a concave (constrained) tibial implant and 11 a posterior-stabilised prosthesis. Eleven normal knees served as a control group.In the posterior-stabilised knees there was less proximal and posterior displacement of the centre of the tibial plateau during extension from 45° to 15°, with a decrease in the anterior translation of the femoral condyles of 4 mm at 45°. There was less internal tibial rotation and increased distal positioning of the centre of the tibial plateau with both designs when compared with the normal knees, and in both the centre of the plateau was displaced posteriorly by more than 1 cm.Increased AP translation has been recorded in all prosthetic designs so far studied by radiostereometry. The use of a posterior-stabilised design of tibial insert could reduce this translation but not to that of the normal knee.
