With an growing old baby-boomer technology, it ought to come as no shock that the variety of hip and knee substitute procedures have skyrocketed. The Nationwide Inpatient Pattern (NIS) exhibits that major hip replacements elevated by 48%, from 153,080 procedures in 1997 to 225,900 in 2004. First-time knee replacements grew by 63% from 264,331 in 1997 to 431,485 in 2004.
