HealthDay News — From 2000 to 2010, the rate of total knee replacement increased considerably, with a higher rate for women than men in 2000 and 2010, according to a September data brief published by the U.S. Centers for Disease Control and Prevention’s National Center for Health Statistics.

Sonja N. Williams, MPH, and colleagues from the NCHS used data from the National Hospital Discharge Survey to present trends in the rate of hospitalizations for total knee replacement from 2000 through 2010.

The researchers found that from 2000 to 2010 there was an increase in the rate of total knee replacement for both men and women (86 and 99%, respectively). Women had a higher rate of total knee replacement than men for both 2000 (33.0 versus 24.3 per 10,000) and 2010 (65.5 versus 45.3 per 10,000). From 2000 to 2010, for men and women aged 45 years and older, the mean age at total knee replacement decreased. In 2000 and 2010, higher percentages of men than women aged 45 and over who were hospitalized for total knee replacement were discharged home (69.8 and 54.1% for men and women, respectively, in 2010 versus 53.5 and 40.8% for men and women, respectively, in 2000).

“From 2000 through 2010, total knee replacement was among the five most frequent of all inpatient procedures, and it was the most frequent procedure in 2008, 2009, and 2010,” the authors wrote.
