  • Summary: Trends of prostheses implants in Orthopaedic surgery

    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'è un sito dell'American
    Association of Orthopaedic Surgeons :
    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
    a large volume of information on total joint demographics in the book.

    In their interesting editorial (Total Knee Replacement: The Joint of the
    Moran CG, Horton TC BMJ. 2000;320:820), Dr. Moran and Dr. Horton
    how total knee replacements have undergone a period of convergent
    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
    for 15 years. Patients with failed total joints often seek a second
    and are referred to a subspecialist for revision surgery.
    "Worst case" analysis in which all patients who are lost to follow-up
    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
    The long-term survival of knee replacements appears to be better than
    of hip replacements.
    There is a large unmet need for knee replacement in the United Kingdom,
    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
    statistics you are looking for (though only for U.S. patients). Contact
    Academy at for more information if you are interested.

    I dati più significativi che ho mai trovato sono al
    sotto l'AAOS, appena aggiornati al '97 (arrivavano al '95)

    I would suggest you try the US National Center for Health Statistics,
    They have an impressive amount of statistical data. One which might
    interest you:
    Vital and Health Statistics, Series 13, No. 139 (11/98)
    Summary: Ambulatory and Inpatient Procedures in the United States, 1996
    Series 13: Data From the National Health Care Survey No. Methods
    in this report are based on data collected from the National Hospital
    Discharge Survey (NHDS) and the National Surv
