It is associated with significant economic burden to individuals and health systems. This study examined the real world prevalence, pattern and cost of physiotherapy for OA in Nigeria. Methods: A retrospective study of all cases of OA seen over a 10 year (2009 and 2018) period at the Obafemi Awo-lowo University Teaching Hospitals Complex, Île Ife, Osun State, Nigeria was con-ducted. A 10 year (2009 and 2018) record of all cases of OA were assessed. Data were gleaned on socio-demographics, treatments administered and the costs of physio-therapy. Both direct and indirect costs were estimated using the cost of illness approach. Data were summarised using descriptive statistics of mean, standard deviation (SD) and frequency. Inferential statistics of t-test and ANOVA were also used to analyse the data Results: The prevalence of OA was 3.6% of all cases over a 10 year period. The mean (SD) age of patients was 62.1 (9.3) years, and 80.9% of them werewomen. OA of the knee was the commonest and often presented with pain (100%),swelling (44.1%), crepitus (77.9%), reduced range of motion (77.2%), and deformity(34.6%). The most common physiotherapy interventions used were strengtheningexercises (58.8%) and soft tissue massage (98.5%). 24.3% and 13.2% of the patients also received infrared radiation therapy, and other modalities such as ultrasound and transcutaneous electric nerve stimulation, respectively. Physiotherapy interventions had significant effect on pain (p = 0.001). The annual mean (SD) direct and indirect costs of OA were 36.1367.87 and 144.52631.49 USA dollars (USD), respectively. Conclusions: Real-world prevalence of OA was relatively low in Nigeria with the knee joint most frequently affected. Physiotherapy interventions were effective for reducing pain in patients with OA.
