Abstract: Total elbow arthroplasty is a common surgical procedure used to replace diseased joints with an implant attempting to restore at least partially the lost functionality of the articulation. Given the relative paucity of studies attempting to simulate implant kinematics during insertion motions, the primary objective of the present study was to assess the feasibility and performances of conventional numerical computer-aided engineering (CAE) techniques in this biomechanical context. The results obtained revealed that while both CAE-driven and experimental navigated implantation techniques will yield comparable FE axis misalignment errors, the numerically-simulated approaches seem to be capable of providing more insight on the motion dynamics/kinematics due to their inherent level of maturity. Based on this, it was concluded that numerically-simulated techniques offer less invasive and more comprehensive means for implant motion control and visualisation, and therefore they should be further perfected for implant design as well as preoperative virtual surgery applications.
