“…A N U S C R I P T 8 measurements (Leszko et al 2008;Cenni et al 2013) and also in accordance with the reported increased laxity after total ankle replacement (Watanabe et al 2009). For the ME case, the axial loading was thus also displaced anteriorly.…”

“…Besides, since we had no information about the donor, we applied the same loading to all tibias, which is certainly not fully consistent with real life. The eccentric case simulated here covered reported extreme displacements of the mobile bearing (Siegler et al 2005;Reggiani et al 2006;Leszko et al 2008). …”

“…Poisson's ratio was 0.3 and the elastic Young's modulus was estimated from the Hounsfield number of CT images of the cadaveric tibias (Keller 1994). The tibial and talus metallic We simulated maximum loading during stance phase of walking, and thus assumed an angle of flexion of 0 degrees (Leszko et al 2008). The loading conditions were derived from the ASTM F2665 protocol (2014).…”

“…The eccentric cases simulated here covered reported extreme displacements of the mobile-bearing insert (Siegler et al, 2005;Reggiani et al, 2006;Leszko et al, 2008). The main limitation of the model was the use of non-fresh cadaveric bone, which were perfused and conserved 4 years in a formaldehyde solution.…”

a b s t r a c tTotal ankle replacement remains a less satisfactory solution compared to other joint replacements. The goal of this study was to develop and validate a finite element model of total ankle replacement, for future testing of hypotheses related to clinical issues. To validate the finite element model, an experimental setup was specifically developed and applied on 8 cadaveric tibias. A non-cemented press fit tibial component of a mobile bearing prosthesis was inserted into the tibias. Two extreme anterior and posterior positions of the mobile bearing insert were considered, as well as a centered one. An axial force of 2 kN was applied for each insert position. Strains were measured on the bone surface using digital image correlation. Tibias were CT scanned before implantation, after implantation, and after mechanical tests and removal of the prosthesis. The finite element model replicated the experimental setup. The first CT was used to build the geometry and evaluate the mechanical properties of the tibias. The second CT was used to set the implant position. The third CT was used to assess the bone-implant interface conditions. The coefficient of determination (R-squared) between the measured and predicted strains was 0.91. Predicted bone strains were maximal around the implant keel, especially at the anterior and posterior ends. The finite element model presented here is validated for future tests using more physiological loading conditions.

“…Particularly in Europe, the appearance of new-generation, mobile-bearing, cementless prostheses has renewed interest in TAA [5,11,24,33,48,[51][52][53]. The theoretical advantages of TAA compared with arthrodesis are maintaining joint ROM and restoring more normal kinematics in the hopes of providing the patient with greater comfort and better functional recovery [7,31,33,35,49]. The disadvantages are related to the risk of mechanical complications with failure sometimes requiring implant removal along with subsequent arthrodesis, which can be technically demanding and lead to a less satisfactory result than with primary arthrodesis [10,19,47].…”
