Current progress of Mechanical Engineering in conjunction with the Biomedical
area have allowed the development of devices that contribute to heal and
relieve human suffering. Within skeletal disorders, Osteoarthritis (OA), is a
progressive and irreversible chronic disease whose main characteristic is the
degeneration of articular cartilage. Where, one of the great challenges is the
development of devices and materials to prevent the evolution of the disease,
applying minimal invasive procedures that provide the relief of pain and an
increased range of joint mobility. The prior suggest that the patient can undergo
surgery without complications in a short and long term. Therefore, it is
necessary to evaluate the mechanical behavior of an implant that counteracts a
body load with a force of 127 N, with the purpose to mitigate OA by
implementing tools provided by Computer Aided Engineering (CAE). In order to
validate the design, before the process of rapid prototyping and manufacturing,
a structural numerical analysis of a linear-elastic type was performed by the
Finite Element Method. In the pre-processor, the form factors, the properties of
the biocompatible materials, the boundary conditions and the external agents
are previously analyzed in a free body diagram in order to evaluate the total
displacements and the stress field developed in each one of the elements of the
implant. Finally, through the analysis of the principal stresses obtained for the
system, appropriate safety factors were obtained, ensuring correct operation
and thus allowing to avoid possible failures in the mechanical device once
implanted.
