I was examined by a podiatrist after an ankle sprain-type of an accident.
I have doubt that his examination wasn´t fully reliable.

He made this test which I think was similar or very close to anterior drawer test for ATFL (his pulling may have been more plantar- than anterior-directed):
I was lying on my back with my ankles and feet outside the plinth, then he grabbed my calcaneus and pulled gently (ankle with sprain-like accident). I said out loud to him: why do I feel a clunk? I didn´t feel the same clunk/gap when he pulled the calcaneus of the un-injured leg. He answered me that "it´s good that there´s space there". And he didn´t diagnose anything assuming ATFL-injury.

Is it possible for the patient to feel a clear clunk-feeling with anterior drawer test, but still have a negative test result?
Really sadly, there was a motive for the podiatrist to neglect diagnosing a possible injury.
