Osteoarthritis (OA) is the leading cause of musculoskeletal pain and functional disability worldwide. However, the etiology of this condition is still largely unknown.
Case Report: We report the clinical course of an elderly man with knee OA.
Conclusions: Plain radiographs and MRI examinations performed during follow-up suggested that the pathophysiology of the patient’s knee OA and joint pain may have been primarily due to bone alterations.
