“…Especially, studies focus on stresses at the joint, i.e., between the femoral component and tibial insert to reveal the effects of implant materials, sagittal radius, flexion angle (Shashishekar and Ramesh, 2007), various implant designs (Usman and Huang, 2018), surgical decisions (Su et al, 2020), or misalignment (Pang et al, 2016;Moewis et al, 2018) on the function of the knee joint. Other scientific articles on FEA focus on developing custom-made knee implants (Sun et al, 2015;Li et al, 2017) or conducting "what if " studies about implant positioning during TKA (Mou et al, 2018). Moreover, studies, such as Stanev et al (2016Stanev et al ( , 2020 and Benos et al (2020) that use musculoskeletal and finite element (FE) models of the knee to predict surgery's effect in a pre-operative manner might be an interesting extension of this work for TKR.…”
