Figure Lengend Snippet: Survey of three-dimensional knee contact models where bone poses are determined using multibody rather than finite element methods. Bones are treated as rigid bodies possessing rigid or deformable contact surfaces. Only one study was dynamic and used a full-body rather than knee-only model, though this study used rigid rather than deformable contact theory.

Article Snippet: The first application involves static analysis (via dynamic simulation) of a natural knee model and the second is a dynamic simulation of an artificial knee model. A commercial multibody dynamics simulation code (Pro/MECHANICA MOTION, Parametric Technology Corporation, Waltham, MA) was used as the test bed for both models, where the tibia was welded to ground and the femur connected to the tibia via a six degree-of-freedom joint.

Article Snippet: As a reference for validating experimental results obtained with the VIVO joint simulator, a musculoskeletal multibody system (MMBS) model of the human lower extremity was built up using the multibody simulation software SIMPACK (Version 2022x, Dassault Systèmes, France).
