Introduction
The 2004 edition of the Journal Citation Reports (JCR), published by the Institute for Scientific Information (ISI), lists 5968 journals in the Science Citation Index (SCI). Documents used in this study were based on the database of the SCI subscribed from the ISI Web of Science, Philadelphia, PA, USA. “Osteoarthritis” was used as keywords to search titles, abstracts, or keywords. Articles, corrections, addition corrections, editorial materials, letters, meeting abstracts, news items, notes, reprints, and reviews were obtained from the results of the search for document types. Articles would have further analysis in this study. Articles originating from England, Scotland, Northern Ireland, and Wales were grouped under the UK heading. The impact factor (IF) of a journal was determined for each document as reported in the JCR Collaboration type was determined by the address of each author, where ‘single country’ was assigned if researcher’s addresses are from the same country. ‘International collaboration’ was assigned if the paper was cosigned by researcher’s addresses from more than 1 country.
Purpose
Bibliometrics is a type of research method used in library and information sciences. The aim of this study was to understand the distribution and frequency of osteoarthritis research by using bibliometric mapping method.
Methods
Database was conducted from SCI between 1991 and 2004.
Results
During the period 1991 and 2004, there was more than a 4-fold increase in both the annual number of articles published and the number of pages devoted to osteoarthritis research. The difference of the cumulative trend was significant between the two periods from 1991 to 1996 and 1996 to The exponential relation indicates that the yearly articles sustain constantly growth rate on publications after A total of articles were published in 1103 journals including specialty journals, but also journals of other disciplines. The most frequently published journals for osteoarthritis research were The Journal of Rheumatology (757, 7.4%), followed by the Osteoarthritis and Cartilage (678, 6.6%), and Arthritis and Rheumatism (578, 5.6%). Sixty-nine percent of articles were published in journals with an IF of lower than 3. In 1996, there were 72 articles with radiographic assessment of osteoarthritic knee, 15 articles were CT methods, 53 were MRI and 56 were arthroscopy. In 2004, there were 307 articles in radiographs, 72 in CT, 316 in MRI and 247 in arthroscopy.

Conclusion
We concluded that osteoarthritic knee research on MRI has been exceeding arthroscopy and X-rays, and much beyond CT scan, and we encourage more research publications on imaging journals.
