The development of osteoarthritis is dependent on age, sex, genetic predisposition and previous trauma to the joint and abnormal mechanical forces caused primarily by obesity. Biochemically, there is an imbalance in the enzyme of cartilage degradation and cartilage regeneration that is involved in pathogenesis of osteoarthritis. 1Prevalence of Knee osteoarthritis is reported to increase in females during premenopausal age and remains high throughout menopause. The reason for this is revealed in many studies that, loss of oestrogen at the time of menopause increases a woman's risk of getting osteoarthritis. 2 ABSTRACTBackground: Osteoarthritis (OA) is a chronic degenerative joint disease. Prevalence of knee osteoarthritis is reported to increase in females during premenopausal age and remains high throughout menopause. The Indian elderly population has increased to 8.6% in 2011 census, with life expectancy of 68.2 years. This has led Indian women to live with problem of osteoarthritis for long time as compared to other countries. Osteoarthritis is also associated with decreased physical activity and in turn affecting health related quality of life. Hence this study is taken up to estimate the prevalence of osteoarthritis and to assess the treatment seeking behavior of women in the community. Methods: A community based cross sectional study was conducted on 120 women above the age of 40 years from January to March 2015 in urban field practice area of BMCRI. Data collection was done by house to house visit. Information was collected by using a pre-tested, semi-structured questionnaire. Results:The estimated prevalence of knee osteoarthritis among women aged 40 years and above was 55% (66). Out of 66 women who had osteoarthritis 68.2% were currently on treatment. We also found that 65.2% (43) of the women had difficulty in doing daily routine activities. Conclusion:The high prevalence of knee osteoarthritis is due to majority of women is developing osteoarthritis at a younger age. This is leading to decrease in quality of life of women at a younger age group in the community.

A Cross-sectional Study to Estimate the Proportion and Ascertain Risk Factors for Osteoarthritis Knee among Women above 45 Years of Age Attending a Tertiary Care Hospital

“…The proportion of OA Knee among women above 45 years of age in our study was 69.2%. The prevalence reported in our study is more as compared to the study done in Bangalore and Delhi,[ 5 9 ] where the prevalence of osteoarthritis knee in women above 40 years of age was found to be 55% and 47.3%, respectively, due to the fact that our study is hospital based in orthopedic OPD setting and we used ACR clinicoradiological diagnostic criteria which has a sensitivity of 91% and specificity of 86% for diagnosis. On the other hand, other studies were community based and ACR clinical criteria which have a sensitivity of 95% and 69% specificity were used for the diagnosis of OA knee.…”

“…American College of Rheumatology (ACR) clinical and radiographic criteria (knee pain and any one of the following- >50 years of age, morning stiffness >30 min, crepitus plus osteophytes), which has a sensitivity of 91% and specificity of 86%, was used for diagnosis of knee osteoarthritis. [ 4 ] Using the formula n ≥ Z 2 PQ/ e 2 , substituting the prevalence of osteoarthritis knee as 55%(P),[ 5 ] Q as 100 − P (45%), Z as 1.96 at 95% C.I., and allowable error(e) as 5%, we calculated the sample size to be 380. Convenient sampling technique was used.…”

A study to assess the quality of life among the women with osteoarthritis

“…More than half of women (57%) who were suffering from osteoarthritis did not seek any treatment. (Salve et al, 2010) In another study conducted by (Narasimha et al, 2016). we also found there was a signi icant association between prevalence of knee osteoarthritis and BMI of study participants (p-0.04) and also there was a signi icant association between osteoarthritis and activities of daily living (Chi-38.7, df-1, p<0.001).…”
