“…3 Modeling the humeral cartilage as a rigid structure is also a modeling assumption; however, this approach has been used by a number of other finite element models modeling soft tissues. 2,8 This was done for a number of reasons: (1) this approach has been shown to be acceptable under moderate loading conditions 8 and is supported by the work of Ellis et al 18 ;…”

“…However, this will inevitably lead to discrepancies between the simulated results and the realistic Normally, the first step in FE shoulder modelling is to reconstruct the 2D or 3D geometry of hard tissues and soft tissues of the musculoskeletal structure. Different approaches have been used for acquiring the dataset for the geometric construction varying from using literature data [71], average measured data [36] to subject-specific medical imaging data [31,32,39,41,44,45,48,52,53,56,[58][59][60]62,66,68,84]. For geometric construction of bones, the most widely used approach is based on computed tomography (CT) imaging data, for example, the CT image databases for the modelling of the cervical spine and hip joint in our previous studies [85,86].…”

“…While in some studies the bone geometry was measured directly in cadaveric dissections or used the datasets from literature [32,39,48,56]. For geometric modelling of soft tissues, such as musculotendinous units and ligaments, datasets obtained from magnetic resonance (MR) imaging or colour cryosections were normally used [32,41,44,45,48]. However, the geometric reconstruction of articular cartilages still remains challenging.…”

“…Multibody dynamics software studies may be used to simulate the effect of ligament deficiencies on the knee and provide faster joint analyses over wide ranges of motion [20]. However, any modeling solution should accurately represent the ligament and muscle lines of action and moment arms to realistically simulate joints, and inaccurate information about the soft tissue lines of action and moment arms may preclude complete kinematic joint simulation [21][22][23][24].…”
