چکیده
Abstract Wear is one of the main mechanical factors that limits survival total knee replacements (TKRs) and it known to be highly dependent on local kinematics joint. In this study, an analytical wear model was coupled a multibody dynamic obtain distribution at lateral medial contact plateaus different TKRs. The major aim analyze if can indicator elevated tibiofemoral misalignment which lead rapid TKR failure. For simulations, commercial prototype geometries were used, with augmented Archard’s law. Squat movement chosen due its importance both in sports everyday life. As conclusion, new parameter, denoted as imbalance, introduced, indicate whether TKR, geometrical features, prone subjected

در طی چند دهه ی اخیر، مفهوم «تراژدی» و «قهرمان تراژدی» توجهی روزافرون را تقریباً در تمام حوزه های نقد ادبی به خود معطوف کرده است. برخی نظیر ارسطو، نیچه، و آرتور میلر به بازخوانی آن پرداخته و برخی دیگر نظیر سارتر، استریندبرگ، یوجین اُنیل، برتولت برشت، و آنتونین آرتود به افزودن ابعاد نوینی به این مبحث همت گماشته اند. آنچه قهرمان تراژدی مدرن را از مفهوم کلاسیک آن متمایز می کند نه لغزش تراژیک متداول ...
Multibody dynamic simulation of knee contact mechanics.
Multibody dynamic musculoskeletal models capable of predicting muscle forces and joint contact pressures simultaneously would be valuable for studying clinical issues related to knee joint degeneration and restoration. Current three-dimensional multibody knee models are either quasi-static with deformable contact or dynamic with rigid contact. This study proposes a computationally efficient met...
