| Popis: | This study aimed to determine the clinical applicability of the new TKA by evaluating biomechanical stability through measurement of contact pressure and strain distribution in the proximal tibia during the stand-sit-stand motion. The reaction forces generated during knee flexion from 0° to 140° were measured in eight men (25±2 years, 23±4 kg/m2) using two force-plates integrated with a computer-aided video motion capture system and were used for load applications in the mechanical test to identify the contact pressure and strain distribution in the tibia with the new TKA. The results indicate that the new TKA may be appropriate for sharing and transfer of physiological loads on the tibia without critical damage to the tibia and TKA during the high deep flexion associated with the stand-sit-stand motion. |
