“…No aconselhamento dos doentes é fundamental encontrar um equilíbrio que garanta os benefícios do exercício físico e, em simultâneo, não reduza a longevidade da prótese. 19 Assim, a decisão sobre a prática desportiva deve ser tomada caso-a-caso, de forma partilhada com o doente, explicando os riscos e benefícios da prática do exercício físico e equacionando fatores como a idade, nível de atividade prévia e expetativas do doente.…”

The use of megaprostheses is increasing in orthopedic field and physical exercise (PE) in these patients is considered dangerous. The purpose of this paper is to understand which PE level these patients achieve. This review comprised 5 articles based on research made in Pubmed® with the keywords megaprosthes* AND sports [MeSH term]. UCLA score varied between 4 and 7, with the maximum value obtained in patients with humeral reconstructions. 2 studies found a correlation between pre and postoperative PE level. Walking, bicycling, and swimming were the most performed activities. Low, medium, and even high-impact activities may be performed by well selected patients. However, more studies are needed, to a better counseling, and factors as age, preoperative PE level and patient expectations should be considered.

The purpose of this computational study was to analyze the effects of different mobile-bearing (MB) total knee replacement (TKR) designs on knee joint biomechanics. A validated musculoskeletal model of the lower right extremity implanted with a cruciate-retaining fixed-bearing TKR undergoing a squat motion was adapted for three different MB TKR design variants: (I) a commercially available TKR design allowing for tibial insert rotation about the tibial tray with end stops to limit the range of rotation, (II) the same design without end stops, and (III) a multidirectional design with an additional translational degree-of-freedom (DoF) and end stops. When modeling the MB interface, two modeling strategies of different joint topologies were deployed: (1) a six DoF joint as a baseline and (2) a combined revolute-prismatic joint (two DoF joint) with end stops in both DoF. Altered knee joint kinematics for the three MB design variants were observed. The commercially available TKR design variant I yielded a deviation in internal-external rotation of the tibial insert relative to the tray up to 5° during knee flexion. Compared to the multidirectional design variant III, the other two variants revealed less femoral anterior-posterior translation by as much as 5 mm. Concerning the modeling strategies, the two DoF joint showed less computation time by 68%, 80%, and 82% for design variants I, II, and III, respectively. However, only slight differences in the knee joint kinematics of the two modeling strategies were recorded. In conclusion, knee joint biomechanics during a squat motion differed for each of the simulated MB design variants. Specific implant design elements, such as the presence of end stops, can impact the postoperative range of knee motion with regard to modeling strategy, and the two DoF joint option tested accurately replicated the results for the simulated designs with a considerably lower computation time than the six DoF joint. The proposed musculoskeletal multibody simulation framework is capable of virtually characterizing the knee joint dynamics for different TKR designs.
