" The last resort is joint-replacement surgery, in which the damaged joint is removed and replaced with a prosthetic. Part or the entire joint may be replaced. In a procedure, called hip resurfacing, instead of removing the damaged hip ball, it is reshaped and capped with a metal prosthesis. Leaving more bone intact may be beneficial down the road if a second hip replacement is needed. More than 200,000 hip replacements and 600,000 knee replacements are performed every year in the U.S. By 2030, the numbers are expected to soar to 572,000 annual hip replacements and 3.48 million knee replacements, according to the American Academy of Orthopedic Surgeons."
Thought it was interesting but not that informative to all the benefits of HR. The Mayo clinic article which links off the Hip resurfacing term is very weak.
FYI
