"The problem is that the average life of the prosthesis
is approximately fifteen years. That is why doctors prefer to wait as long as
possible with the replacement and they prefer not too young patients.
"Because you want about fifteen years, which have to offer," says
Reich. Who has not hurt the worn knee is not operated. Williams adds: "And
you want to actually prefer to be ready at once."
Bend without rapid wear knee
But there is good news.
Recently used the orthopedic surgeons in the MCL after a
long and intensive search by producers and international conferences a new type
of prosthesis
Williams: "The weakest link in the artificial knee was
and is a polyethylene plate, which turns the metal hinges. That plate wear over
time. "Simply a man bends his knees often terrible. But now there is a
picture of a new, much harder type of polyethylene.

Better fit artificial knee
A further development is that of the introduction of special
knee prosthesis for women.
Rich: "There used to be different sizes, but women were
basically the same prosthesis as men. While women generally leaner knees and
have another fit. "
The right fit is less friction and thus a longer life of the
prosthesis.
