A retrospective analysis of trends in primary knee arthroplasty in Germany from 2008 to 2018

Abstract Unicompartimental and total knee arthroplasty is one of the most successful and most performed operations worldwide. In the last years the number of primary knee arthroplasty increased constantly. The aim of this study is to analyze the rising numbers of primary knee arthroplasty and to see...

We found that the number of bicondylar TKA and especially UKA increased from 2008 to 2018.
