I might say in ward rounds that "knee flexion is a contra-indication"




Why "knee flexion is a contra-indication" rather than "is contra-indicated"? I'm asking from a position of the utmost ignorance, motivated by genuine curiosity.




Good question. I would think that "knee flexion is a contra-indication" would mean that if the patient bends a knee it would mean that there's something else that would be contra-indicated.
