ABSTRACT

The prevalence of osteoarthritis among elderly is high and it majorly affects the quality of life. Knee osteoarthritis is the most common form of osteoarthritis. Timely diagnosis using clinical criteria and effective intervention is of utmost importance. To estimate the prevalence and determinants of osteoarthritis of knee joint among elderly persons using ACR clinical criteria. Materials and Methods: We did a community-based cross-devotional study among 496 elderly (>= 60 years) persons .India from December 2009 to February 2010. The American College of Rheumatology (ACR) criteria was used to clinically diagnose osteoarthritis knee. Statistical Analysis: Bivariate analysis using Chi-square test and multivariate analysis was done to identify the determinants. Sensitivity and specificity of individual factors to diagnose osteoarthritis knee was calculated. The prevalence of osteoarthritis was estimated to be 41.1% (95% C.I., 36.7-45.6). Female sex and age >= 70 y were found to be independent risk factor for osteoarthritis knee. Among those having knee pain, presence of crepitus and tenderness were the most sensitive factors whereas bone overgrowth and bone warmth were most specific factors. The prevalence of osteoarthritis knee was high among this elderly population and increased with age. Overall, individual factors of ACR criteria were both sensitive and specific in diagnosing osteoarthritis knee. In resource constrained setting of urban India, it can be an effective tool in clinical diagnosis of osteoarthritis knee.
