-- This means that abnormalities on imaging do not necessarily correlate with symptoms. Plenty of people are walking around with torn rotator cuffs, meniscal tears, arthritis and the like without any actual symptoms. More importantly, plenty of people incorrectly think that their symptoms can't be fixed because imaging shows something is irreversibly wrong.
