Of Knee Replacements and Mood Rings: Does Your Psychological Profile Determine Outcome?

By /

knee replacement and personality types Interesting paper out this week which tries to tie knee replacement outcome to temperament. I have to admit that not being in psychiatry, I had to look up and research some of these terms like sanguine and choleric. Melancholic and neurotic were a bit easier to understand. Basically, in a small study where patients who had already had a knee replacement were personality tested; the researchers tried to tie the pain/functional outcome as well as the patient satisfaction to personality traits. These traits are known as “The Four Temperaments” (which sound like they were introduced about the same time as there were four corners of the kingdom). So I know you neurotics out there are wondering who did the best and whether it was you or if not then who, maybe you could guess, but no, just tell me because it’s killing me… You cholerics are just trying to get this whole damn thing done and crossed off the list… You sanguines are just happy to be here and this whole thing has made you melancholics a bit depressed…so the winner is… Well the “just happy to be here” sanguine had the best pain and functional outcomes. The let’s get this done cholerics had the best satisfaction and the melancholics did the worst. The neurotics…I’m not going to tell you just to mess with you.
