“…In parallel to the clinical studies, modern techniques such as 3D reconstruction, simulation, high‐speed cameras, gait analyzes, etc. are increasingly used to analyze the separate biomechanical concepts and thereby to explain the differences in the results [4, 6, 15–17, 20, 22, 27]. These studies can make basic statements about the biomechanical characteristics of the unique alignment concepts.…”

Purpose Total knee arthroplasty (TKA) is nowadays performed as a standard procedure on a large number of patients suffering from arthrosis. Replacing the knee joint causes changes in the geometry and kinematics of the knee, which are unique to each individual. This research focuses on the method to detect these changes after TKA and on the impact on the knee movement. This approach could reduce complications in patients with post-operative pain and reduce the number of revisions. Methods A 3D model of a patient’s knee was made by measuring the movement with a medically certified infrared stereo camera. This measurement was combined with the 3D model of the patient’s bones, previously segmented from the CT scan. This model is printed in 3D, one part being the mechanism that follows the movement of the patient, and the other part being the 3D copy of the femur and tibia bones. The knee replacement operation is performed directly on the model and the resulting rollback is being measured before and after TKA. Results We observe a difference in the rollback before and after TKA on the 3D printed model. The variation in size and shape of the femoral implant compared to the natural femur condyles is one of the reasons for the changes in the rollback effect. The rollback is half as large after the prosthesis insertion, which confirms the fact that the femoral prosthesis geometry influences the knee kinematics. Conclusions In this study, a first 3D model combining the patient-specific kinematic and the geometry of his bones has been constructed. This model allows the surgeon to validate the plan of the operation, but also to understand the problems and consequences generated by the prosthesis insertion. The rollback is one of the most important motion of the knee joint and this behavior could be quantified, providing comparative analysis of the knee joint before and after the operation. As a future study, the model could be used to analyse more parameters of the TKA such as the impact of different implantation methods.

This chapter aims at presenting a concise picture of the research in Biomechanics developed by researchers of various disciplinary areas that refer to AIMETA. The research collectors are the international journal Meccanica, published by Springer, and the AIMETA congresses including publications of studies presented therein. This chapter is devoted to studies related to AIMETA activity and mainly refers to the topics from the above-mentioned sources. Final comments and future developments are outlined. Keywords Biomechanics • Biological tissues • Articular biomechanics • Medical devices • Biological fluid mechanics • Cardiovascular mechanics 1 Introduction, from Mechanics to Biomechanics Biomechanics is the science that studies the structure and function of biological systems using methods and knowledge of Mechanics. The birth of Biomechanics can be dated back to the first studies of Aristotle (384-322 BC) and later developed by Galen (129-210), Leonardo da Vinci (1452-1519), Galileo Galilei (1564-1642), and Giovanni Alfonso Borelli (1608-1679, up to a few further advancements through the nineteenth and twentieth centuries. It found in the last 50 years a rebirth of interests that became an exponential growth in the last 20 years. In the 50's of the past century, it was in fact considered a subject for

Background: Intraoperative surgical planning tools (ISPTs) used in current-generation robotic arm-assisted total knee arthroplasty (RTKA) systems (such as Navio ® and MAKO ® ) involve employment of postoperative passive joint balancing. This results in improper ligament tension, which may negatively impact joint stability, which, in turn, may adversely affect patient function after TKA. Methods: A simulation-enhanced ISPT (SEISPT) that provides insights relating to postoperative active joint mechanics was developed. This involved four steps: 1) validation of a multi-body musculoskeletal model; 2) optimization of the validated model; 3) use of the validated and optimized model to derive knee performance equations (KPEs), which are equations that relate implant component characteristics to implant component biomechanical responses; and 4) optimization of the KPEs with respect to these responses. In a proof-of-concept study, KPEs that involved two component biomechanical responses that have been shown to strongly correlate with poor proprioception (a common patient complaint post-TKA) were used to calculate optimal positions and orientations of the femoral and tibial components in the TKA design implanted in one subject (as reported in a publicly-available dataset). Results: The differences between the calculated implant positions and orientations and the corresponding achieved values for the implant components in the subject were not similar to component position and orientation errors reported in biomechanical literature studies involving Navio ® and MAKO ® . Also, we indicate how SEISPT could be incorporated into the surgical workflow of Navio ® with minimal disruption and increase in cost. Conclusion: SEISPT is a plausible alternative to current-generation ISPTs.
