Joints and teeth are the last frontiers in modern medicine; its
help is least developed compared with other areas.

Jim was in US Special Forces in combats and as a trainer. He had
both knees replaced with titanium joints. Jan's husband, too.
Mike also. Judy, Ron's wife is planning to have it too.

Cartilages in all joints cannot be regenerated, only replaced
with titanium joints, when enough is worn out mostly by excess
wight.

But the most worn-out portions of cartilage can be taken out
and transplanted from your own still-healthy parts of your
knee cartilage, relieving the pain. It is not as good as the
healthy original, but it does take maximum advantage of the
diminishing resources. The repair will wear out too if weight
control is not maintained. Of cource, there is no immunological
rejection problem since the transplant is your own tissue.

Since we live longer and longer, let's take care of our precious
knee joints in advance.
