Background: Osteoarthritis, (OA) the most common of all the types of arthritis, is a significant public health problem which contributes greatly to disability in the elderly. Community-based prevalence studies of OA in South-Western Nigeria were scanty for referencing. Objective: This study investigated the prevalence of symptoms of self-reported knee OA (KOA) in a heterogeneous community of Odo-Ogbe in Ile-Ife, South-Western Nigeria. Methods: All houses in Odo-Ogbe community were numbered, and all odd numbered houses were selected for the study. Every adult individual of aged 35 years and above living in the selected houses were recruited for the study. The total number of participants was 119 individuals and all of them participated in the study by completing Western Ontario and McMaster Universities Osteoarthritis Index Questionnaire. Their anthropometric variables were also measured. Data were analyzed using descriptive and inferential statistics. Results: There were 99 females and 20 males respondents that participated in the study. Forty-seven (39.5%) had knee pain and other KOA symptoms. Among those with KOA symptoms, six of them were males while 41 (87.2%) of them were females. There was a significant negative relationship (P < 0.001) between academic qualification and pain intensity (−0.292), stiffness (−0.336), and difficulty (−0.267) of participants with KOA. Age was also found to be significantly related (P < 0.001) with all symptom of KOA. Conclusion: The prevalence of symptomatic KOA at Odo-Ogbe community is high, more female were affected, and many of those affected had family history of arthritis.
