This paper examines and summarizes data on knee osteoarthritis (AO) in Community Oriented Program For Control Of Rheumatic Disorders (COPCORD) publications. A literature search was made through PubMed, Google, Proceedings of Asia-Pacific League of Associations for Rheumatology (APLAR) congresses, and Abstracts from APLAR congresses. Data were compiled to examine the prevalence of knee OA and knee pain, sex ratio, urban/rural differences and other risk factors. Data on knee pain and OA were available in a total of 36 COPCORD publications. The pooled prevalence of knee OA was 7.9% in adults above the age of 15 years. It was more common in women. Overweight, squatting and cycling appeared to be modifiable risk factors for knee OA. OA of the knee is the commonest rheumatic disease in studied communities. Further research is needed for identification of its modifiable risk factors and development of strategies for reduction of the community burden of this malady.
