Dear Colleagues,

I want to thank all of you for your contribution ... hereafter you find
a summary of contribution received.

I hope to come soon with some other news.

Per quanto riguarda i dati americani c'č un sito dell'American
Association of Orthopaedic Surgeons :
http://www.aaos.org/wordhtml/home2.htm
in particolare in questa pagina puoi trovare i dati dal 1990 al 1997

One resource on this topic is, "Musculoskeletal Conditions in the United
States", printed by the American Academy of Orthopaedic Surgeons. There
is
a large volume of information on total joint demographics in the book.



In their interesting editorial (Total Knee Replacement: The Joint of the
Decade
Moran CG, Horton TC BMJ. 2000;320:820), Dr. Moran and Dr. Horton
described
how total knee replacements have undergone a period of convergent
evolution,
with most implants adhering to the same basic design principles. Knee
replacement has become one of the most common major surgical procedures,
with almost 35,000 operations performed each year in the United Kingdom.
Survival analysis suggests that 95% will last for 10 years and 85% to
90%
for 15 years. Patients with failed total joints often seek a second
opinion
and are referred to a subspecialist for revision surgery.
"Worst case" analysis in which all patients who are lost to follow-up
are
considered to have failed joints gives a pessimistic (yet possibly more
realistic) estimate of joint survival rates. With these more rigorous
standards, total knee replacements have survival rates of 85% at 13
years.
The long-term survival of knee replacements appears to be better than
that
of hip replacements.
There is a large unmet need for knee replacement in the United Kingdom,
and
the waiting time for surgery is often unacceptably long. Waiting list
management is becoming a major political issue, and it is possible that
standardized priority assessment criteria will be introduced for common
elective procedures.

The American Academy of Orthopaedic Surgeons publishes a book entitled
"Musculoskeletal Conditions in the United States." It contains many of
the
statistics you are looking for (though only for U.S. patients). Contact
the
Academy at www.aaos.org for more information if you are interested.

I would suggest you try the US National Center for Health Statistics,

They have an impressive amount of statistical data. One which might
