Background: Scientific progress in the field of knee and hip arthroplasty has
enabled the preservation of mobility and quality of life in the case of patients
with many primary degenerative and (post-) traumatic joint diseases. This
comparative study aims to investigate differences in scientific performance
between the leading continents in the field of hip and knee arthroplasty.
Methods: Using specific search terms all studies published by the scientific leading
continents Europe, North America, Asia and Oceania listed in the Web of Science
databases were included. All identified publications were analysed and
comparative conclusions were drawn regarding the qualitative and quantitative
scientific merit of each continent.
Results: Europe, followed by North America, Asia, and Oceania, had the highest
overall number of publications in the field of arthroplasty. Since 2000, there has
been a strong increase in knee arthroplasty publication rate, particular pronounced
in Asia. Studies performed and published in North America and those on knee
arthroplasty received the highest number of fundings. Publications regarding hip
arthroplasty achieved the highest average citation rate. In contradistinction to the
others, in North America most funding was provided by private agencies.
Conclusion: Although Europe showed the highest total number of publications,
authors and institutions, arthroplasty research from North America received greater
scientific attention and financial support. Measured by citations, publications on hip
arthroplasty attained higher scientific interest and studies on knee arthroplasty
received higher economic affection
