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.

Background: With aging, women face various health issues, the most common of which are musculoskeletal disorders. Osteoarthritis accounts for 15% of all musculoskeletal disorders in patients above the age of 45 years but receives little attention. This study aims to estimate the proportion of women above 45 years suffering from Osteoarthritis (OA) knee and to ascertain its risk determinants.

Materials and methods: A cross-sectional study was conducted among 380 women above 45 years of age attending the Orthopedic outpatient department of a tertiary care hospital over a period of 18 months. American College of Rheumatology clinicoradiological criteria were used for the diagnosis of OA knee. A predesigned case record form was used to collect information on sociodemographic profile and other risk factors.

Results: Data were analyzed using SPSS version 16.0. Our study found the overall proportion of OA knee to be 69.2%. The Chi-square test was used to find the association of various factors with OA knee. On logistic regression, diabetes mellitus, hypertension, menopause, and increased body mass index were found to be significant for OA Knee.

Conclusion: The study concludes the possibility of prevention of disabilities by early screening for OA Knee in those with risk factors as a part of wellness clinics.
