Comparative Study
[Utilization rates of lower extremity prostheses in Germany and Switzerland: A comparison of the years 2005-2008].
In the United States the use of total hip arthroplasty (THA) has substantially increased over the last decade. It is not known, however, if this trend can be applied to other countries as well. The aim of the current study was therefore a detailed comparison of hip, knee, and ankle arthroplasty utilization rates in Germany and Switzerland in the years 2005-2008 and a secondary comparison with the United States. ⋯ In all three countries the primary rates for hip and knee replacements rose over the years but those for knee arthroplasty to a higher extent. The 2008 revision burden was highest in Germany for both types of arthroplasty. In Switzerland there was a transient revision burden decrease with a new increase from the year 2007 onwards. The US hip replacement utilization rates per 100,000 inhabitants were considerably lower than those in Germany and Switzerland and for knee replacements they were slightly higher.
