Özet (Çeviri)
One of the main reason of the failure of total ankle replacement (TAR) is misaligned implants which mean inserting implants to a wrong position, which is not determined in a surgical procedure, in the bone. The misalignment leads to increase and localize contact pressure leading to the failure of TAR. 3D-Muscuskaleton image-based model was used to simulate the ankle and ankle motion characteristic. Previously developed and validated study of ankle joint complex was adopted to investigate the effect of TAR misalignment on the ankle joint complex. The neutral surface of tibia and talus surface was replaced with the SSCL design implant to mimicking the boundary of the bones surface. For optimally aligned implants according to the surgical procedure should be parallel to each other and have full contact between contact surface. A misalignment was composed by translating, which is 2 mm upward, 2 mm downward, 3 mm anterior, 3 mm posterior, and rotating, which is 10-degree inversion-eversion, and 10- degree internal-external, tibial part of the implant. Simulations were run by ADAMSTM. The results, which are distance mapping, the range of motion (ROM), stiffness, ligament force and strain, and kinematic coupling, were derived by using the applied loads, the displacement, which was produced by motion, and the forces in ligaments. x Misalignment of TAR has a significant influence on the ankle joint complex especially stiffness of the ankle and surface to surface interaction. It changes forces and strains of the surrounded ligaments, as well. Knowledge of the effects of misalignment of TAR can be used as a predictive tool to estimate the most critical misalignment type and to solve critical issues.
