At the 23rd annual meeting of the American Association of Hip and Knee Surgeons in Dallas, Texas, November 8 through 10, 2013, Doctors Lang, Et Al, reviewed a large retrospective database using a Nationwide Inpatient Sample (NIS). They found that the total number of hip replacements increased by 73% in the decade from 2000 to 2009, but breaking that down, it increased by 123% in patients age 45 to 64, and by 54% in patients 65 to 84. This reflects the growing demand for hip replacement in a younger age group who are limited by osteoarthritis. This trend makes it incumbent upon orthopedic surgeons and orthopedic implant manufacturers to try to improve results and longevity as patients can anticipate having implants in their body for a longer period of time.
