Background: The present study was conducted for the Analysis of radiographic findings of Osteoarthritis of knee joint using Kellgren-Lawrence score Materials & methods: Forty patients in all who were suspected of having knee osteoarthritis were enrolled. Prior to the study, informed consent was obtained from each subject and their guardian. Additionally, a thorough clinical history about the onset of symptoms was acquired. The following grades of osteoarthritis were applied to all radiographs using the Kellgren-Lawrence scoring system: grade 0, normal; grade 1, questionable osteoarthritis; grade 2, mild; grade 3, moderate; or grade 4, severe. SPSS software was used to conduct statistical analysis. Results: We examined forty OA patients in total. The patients' average age was 50.11. Thirty percent of the patients were men and seventy percent were women. In terms of radiography, the Kellgren-Lawrence score showed that grades 0, 1, 2, and 3 were observed in 29, 5, 4, and 2 patients, respectively. Notable outcomes were attained when comparing the patient distribution to the Kellgren-Lawrence score. Conclusion: significant outcomes were attained when comparing the patient distribution to the Kellgren-Lawrence score. Key words: Kellgren-Lawrence score, Osteoarthritis,
