I'm not sure I understand your post. My interpretation is correct. The two definitions (medical inadmissibility vs. misrepresentation) are extremely straight forward.
If you go back to the original post that started this thread. You will see that immigrant1 is worried that his PR status is in jeopardy (he has already landed) because he failed to disclose a medical condition to the DMP. Immigrant1 specifically asks about "misrepresentation" because he rightly understands that misrepresentation can cause someone's PR to be revoked even after they land.
Medical inadmissibility is completely different than misrepresentation. Medical inadmissibility can be an issue BEFORE someone lands and can result in a refusal of the PR application. Medical inadmissibility cannot cause problems AFTER someone lands. Immigrant1 clearly states that he has already landed. So medical inadmissibility does not apply to him.
As I said in my original response to Immigrant1, there is nothing to be worried about. A minor elbow injury is not misrepresentation. So he is fine. In fact, failing to mention ANY medical condition very likely won't result in misrepresentation. Misrepresentation is for bigger things like failing to mention children in your application, failing to declare you are married, failing to declare you were in the military, etc.
I hope this clarifies these two definitions for you. Let me know if you have any further questions.
