Figure Lengend Snippet: The developed musculoskeletal multibody simulation model with a cruciate-retaining total knee replacement in the lower right extremity during a dynamic squat motion combining musculoskeletal motion dynamics, knee implants with articular contact definitions, muscles, and ligaments ( A ). Detailed representation of the knee joint with implant components and muscle structures, including muscle wrapping. Note that ligaments are not shown for the sake of clarity ( B ). Investigated implant components with ligament structures of the tibio- and patellofemoral joint ( C ).

Figure Lengend Snippet: Validation of the musculoskeletal multibody simulation (MMBS) model. The MMBS model has been validated in terms of the tibiofemoral contact force ( A ), quadriceps force ( B ) and the patellofemoral contact force ( C ) during a dynamic squat motion. The tibiofemoral contact force is compared against the in vivo measurements of instrumented total knee replacements for three subjects (K1L, K2L, K3R, and K5R) . The quadriceps force is compared against two simulation studies [ , ]. The resultant patellofemoral contact force is an important validation parameter for patellofemoral joint dynamics: it is compared against studies described in [ , ].

Figure Lengend Snippet: Musculoskeletal multibody simulation of the patellofemoral joint during the dynamic squat motion ( A ). Model validity was confirmed by comparing the reported lateral ( B ), medial ( C ), and total ( D ) tibiofemoral contact forces (in unit of body weight BW) of the in vivo measurements (blue, ) to our predictions (red).
