Knee Replacements on the Rise in the U.S.

'cause of the fat.

More seniors are getting their knees replaced with artificial joints, according to a new study of Medicare data.

Researchers found that over the last two decades, the number of first-time knee replacements and re-do procedures more than doubled in the U.S...

Dr. Cram and his colleagues found that between 1991 and 2010, the number of people seeking primary or revision knee replacements grew much faster than the number of elderly patients covered under Medicare: the rate of primary surgeries doubled and the rate of re-dos increased by almost 60%.

At the same time, the proportion of knee replacement patients with underlying health problems such as diabetes and obesity also doubled.

Kudos, fatsos.
