The largest cause by far for knee and hip replacements is people being overweight. Obesity plays a big part in the wearing of joints

In 1997, about 60.2% of primary hip replacements and 69.1% of primary knee replacements were performed in patients ages 65 to 84, Sunny Kim, Ph.D., of Florida International University here, reported in the April 15 issue of Arthritis Care & Research.

But by 2004, the corresponding proportions were 52.1% and 58.4%, respectively.

In 1997, 45- to 64-year-olds accounted for 26.5% and 25.6% of primary total hip and knee replacements, respectively. These proportions grew to 36% and 36.4%, respectively, in 2004.
