Abstract Summary
The in-vivo dynamic characteristic of normal knee joint is valuable for the cure of knee osteoarthritis and knee prosthesis design. In this study, a unique in-vivo experimental evaluated subject-specific finite element musculoskeletal (FE-MS) model with high accuracy intact knee was created and used to investigate the mechanics of knee joint during gait cycle. The predicted results on tibiofemoral and patellofemoral joints could provide the theoretical basis for the treatment of knee joint diseases and knee prosthesis design.
