To evaluate the forces acting on the joint
during everyday activities (...) the loads
that arise during walking and running
movements are crucial. Over the course
of a human life, these loads add up (...) to
appr.1-2.5 million load changes, i.e. the
load shifting from one leg to the other.
During the supporting leg phase, which is
the phase in walking during which the bulk
of the weight rests on one leg, the hip is loa-
ded with 2.5 to 3.5 times the body weight.
During activities such as jogging this weight
can increase to up to six times the body
weight.

an artificial joint is a technical component
which necessarily is subject to wear in the
course of its service life.
Usually a period of 10 to 15 years is rea-
listic in this context. (...) One of the main
problems is the direct contact of joint areas
with each other which are subject to con-
stant friction.
