BACKGROUND: Knee osteoarthritis is a chronic medical condition of public health importance in Nigeria which causes disability and impacts daily activities in the sufferers. This study aimed to describe the physical functionality and self-rated health status of adult patients with clinical knee osteoarthritis presenting at the Family Medicine Department, University College Hospital, Ibadan, Nigeria.METHODS: This was a cross-sectional study of 400 respondents. Knee osteoarthritis was diagnosed clinically using the criteria of the American College of Rheumatology. Morbidities, self-rated health status and physical functionality of the respondents were also assessed.RESULTS: Knee osteoarthritis was diagnosed in 46(11.5%) respondents. Respondents with knee osteoarthritis significantly rated their health worse than those without knee osteoarthritis (p <0.0001). Experience of pain, stiffness and performance of daily activities were significantly worse among respondents with knee osteoarthritis. Those who had knee osteoarthritis had significantly higher waist (p <0.0001), hip (p <0.0001) and knee circumferences (p <0.0001) respectively. Logistic regression analysis showed increasing age (OR=1.103; 95% CI=1.022 - 1.191), self-rated health worse than six months ago (OR=12.562; 95% CI=1.178-125.243), experience of stiffness after waking up in the morning (OR=12.758; 95% CI=3.572-45.569), stiffness after sitting/lying down/resting (OR=21.517; 95% CI=2.213-209.220) and waist circumference (OR=1.225;95% CI=1.017-1.477) to be the most significantly associated with knee osteoarthritis.CONCLUSION: Knee osteoarthritis significantly impairs the health and daily activities of adult patients in Ibadan, Nigeria. Healthcare workers need to screen adult patients routinely at first-contact to detect knee osteoarthritis clinically early and manage appropriately.
