There's a huge amount of confirmation bias in the process of diagnosing musculoskeletal conditions based on imaging studies. When a patient presents with a complaint about pain or lack of mobility then the care team will order imaging, and when they see some anatomic abnormality they'll assume it's causing the symptoms and needs to be surgically repaired. But studies have shown that if we perform the same imaging studies on a random population of subjects we'll find a lot of abnormalities and yet most of those subjects are asymptomatic.
