[Trends in the number of knee and hip arthroplasties: considerably more knee and hip prostheses due to osteoarthritis in 2030].

Abstract

The increase in the number of knee and hip arthroplasties due to OA will probably continue in the coming 20 years. The following developments will probably contribute to this: demographical changes, the increase in overweight, improved long-term outcomes of arthroplasty, more active lifestyle of the elderly and the increasing number of orthopaedic surgeons.
