UWorld#15845
I don't know how to best edit this card but it is wrong. Frequently see septic arthritis described as "resistance to all ranges of motion" in questions. Checked on Amboss and it only mentioned restricted range of motion. Not sure where the 'flexion hurts more than extension' came from. Added correct info to the extra section from UWorld and Amboss.

Going to mark this for deletion since we cannot find any good source & the truth is that all ROM is painful in septic arthritis - passive vs. active is more important, and we have a card on that already
