Background: Knee osteoarthritis is a chronic medical condition of public health importance in this setting. It is mostly diagnosed when preventive measures are no longer practicable due to reliance on the radiological diagnosis. Objectives: To determine the magnitude and risk factors associated with knee osteoarthritis among adult patients presenting at the University College Hospital, Ibadan, Nigeria. Materials and Methods: This cross-sectional study used a semi-structured questionnaire to interview 400 respondents. Knee osteoarthritis was diagnosed clinically using the American College of Rheumatology (ACR) criteria. Results: The point prevalence of knee osteoarthritis was 11.5%. Increasing age, female gender, marital status, low educational status, financial dependency, poor income, obesity, previous knee injury, epigastric pain, peptic ulcer disease, varus deformity of the knee, and poor health status were significantly associated with knee osteoarthritis. Logistic regression analysis showed increasing age (OR = 2. 874, CI = 1. 294-6.381), history of epigastric pain (OR = 57. 044, CI = 1. 693-192.24) and varus deformity of the left knee (OR = 3. 012, CI = 1. 063-8.547) to be the most significant factors associated with knee osteoarthritis. Conclusion: The magnitude of clinical knee osteoarthritis is high among respondents in this hospital-based study. Doctors in primary care should screen patients at first-contact to detect osteoarthritis early and manage appropriately.
