For baby boomers, it seems that joint replacements are as prevalent as iPods are for teenagers. About 500,000 knee replacements and more than 175,000 hip replacements are performed annually, and those numbers are on the rise.
More than 90% of annual knee replacements are total knee replacements (TKR). As the name suggests, in a total knee replacement all of the cartilage and bone that has been damaged from osteoarthritis (or otherwise) is resurfaced. In this resurfacing the damaged cartilage and small amounts of bone are removed.
