Hello Wayne - 

--8<--cut 

CA>> Having a badly damaged knee myself I pay attention when
CA>> new developments or documentaries about such things comes
CA>> my way. 

CA>> I am told that the glue holding the artificial knee joint
CA>> into the bone will let go after some years and needs to be
CA>> re-glued depending how active a person is. 

WC> Yup, watched some medical documentaries. Favorite part is
WC> after drilling when they hammer the three flanged spike
WC> into the bone. 

I don't recall anything like that. I did see them using a tool
to shape the hole to accept the pin for the joint and a tool to
ream out the hole. Painful to watch when you think it might be
your turn some day. :-\ 

CA>> The newer knee joints allow you to turn your foot inward
CA>> and outward relieving some stresses on the glue and giving
CA>> greater flexibility of movement in general. Sort of a ball
CA>> and socket type joint rather than the older 'hinge' type. 

WC> That's the type I saw installed. 

CA>> My now deceased father-in-law had two, one in each knee,
CA>> and said he wished he had had them installed decades
CA>> earlier (no pain after healing). 

WC> My knee's are unfortunately the least of my worries.
WC> Missing 2 1/2 inches of my lumber spine has somewhat more
WC> serious ramifications. 

One of my long time friends brother had a wall fall on him when
he was a housing carpenter. Crushed two vertebra that they
replaced with plastic vertebra. I've seen him, since that time,
lifting heavy objects, climbing ladders, he's even done some
shingling on the side for extra money. He seems to be doing
well with the repairs? 

The _other_ factor is that even people born with one leg
shorter than the other will experience lower back pain as a
result of having their hips tiltled most of the time. It's
possible that if the knees were working properly it would
relieve some stresses from your lower back? 

Not a doctor here nor attempting to be one. Just a concerned
long time suffer of similar ailments.
