In many cases of hip osteoarthritis (OA), patients exhibit symptoms that are discordant with radiography and magnetic resonance imaging findings. We have observed two distinct types of pain in hip OA: motion pain and walking pain. Motion pain typically improves with exercise therapy, whereas walking pain may require surgery. Many patients with motion pain have Kellgren-Lawrence grade 3 or 4 findings. Therefore, the combination of narrative-based medicine and evidence-based medicine is important for selecting the most suitable treatment for patients with hip OA.
