Despite the several years of studies that have been contributed to the human
knee joint in pursue of producing a failure free knee joint protheses, there are
still a lot of rooms for improvement on the available prostheses. In this present
study, a series of analyses on the human tibia has been carried out. The
objectives of the present study were to study effects of stress distribution on
human tibia in various degrees of flexion simulating walking and squatting. The
Finite Element (FE) method was adopted for the analysis. Through the finite
element analyses, data concerning the stress distribution and von Misses stress
during gait cycle and squatting were obtained. The results obtained were
compared with those of the experimental literature for validation. The results of
this present study indicated that low stress value occurs during toe-off simulation
while the high stress value occurs during deep flexion with the knee is flexed
90°. The von Mises stress observed on the medial compartment during these instants were 13.85MPa and 26.84MPa respectively. The obtained average
stress distribution of a gait cycle and deep flexions were 15.29MPa and
25.09MPa respectively. it is worth to note that a high stress concentration occurs
at the tibial plateau, distinctively at the medial compartment. This implies that
under deep flexion a possible unstable fracture will be initiated since the
maximum stress allowable on the tibia is 25MPa.
In conclusion, this kind of research gives a better understanding of the stress
applied on the tibia by body weight that assist on designing Total Knee
Replacement against failure. The result could support in the context of
minimizing contact stress between the tibia bone and the tibial insert |
