Ten percent luck, twenty percent skill, fifteen percent concentrated power of will. Five percent pleasure, fifty percent pain and a hundred percent reason to remember the bane.

The answer to all of this is simply that The Dark Knight Rises is an inexplicably terrible movie in nearly every conceivable way. It’s terrible in a vacuum but as a follow up to The Dark Knight, it’s inexcusably stupid and bad.

He’s wearing plot armor.

So this isn’t explicitly stated in the movie at all. It’s only reasonable to assume such a wound would cause issues.

Some might consider it a plot hole, I think that’s more reserved for when the movie goes again it’s own internal logic. I’m pretty generous with movies in these situations, either the movie is running on its own logic set, like cartoon logic or superhero logic, or maybe it’s just a detail that could be explained, but it’s more effort than it’s worth.

For this example, you could totally put a scene in there where Bruce covers the wound with batbandage, hits himself with adrenaline or something, but the result is pretty much the same, and the audience is probably not going to be too interested if you explain everything.

So it’s a bit yes you’re right, but also a bit just go along with it if you can think of any logical explanation.

its a freakin’ superhero movie. You may as well be asking why Luffy could stretch his arms out so far without breaking bones.

Here’s a real question: How could Superman?

I know

He’s super

but

Its batman. He wears a thick set of plot armor.

Also that movie sucks.

He’s Batman. Duh.

Oh there are these things I call Hollywood wounds. All these wounds that are supposed to be survivable in action movie land but would be very real life threats. Stabbings are nasty, specially in the abdomen. You just got signed to play craps with loaded dice and the casino is abdominal cavity infections. You might survive the bleeding, but the fever can still take you out several days later.

There are others like being shot in the leg or the shoulder. Technically survivable, but will destroy your mobility forever. Another one is vertebral spine fractures (which this batman also miraculously survives). If you can walk again after that it would be after years of rehab, and even then you’d still be in pain the whole time until the day you die. Superhero movies are very unrealistic on their handling of human anatomy.

He only survived because she let him live. As a trained assassin, she would have known exactly where to strike if she had wanted the blow to be fatal. She even tells Bane to keep him alive until Gotham is reduced to dust.

The Bat suit might have absorbed some of the impact, but she still drove the blade in deep. Given the location and depth of the wound, he’s fortunate to have only been temporarily incapacitated. If you’ve ever read or heard firsthand accounts from someone who’s been stabbed, you’ll know it’s one of the worst pains imaginable. It’s as if your brain can focus on nothing but that foreign object inside you. Had he not been in peak physical condition, he likely would have passed out from the pain. Instead, we hear only his moans and gasps for air as he kneels over.

Also, maybe Bane is a medical expert.

There are a couple of movie communities where you can post this.

In movies, wounds that don’t severely damage viral organs are but a scratch.

Of course, the standard joke answer is that he’s the Batman (so he can take it when others can’t).

What about this is a joke answer?

A wizard did it.

Probably applied morphine, adrenaline, and a clotting bandage off screen. He would of course have all of those on him…because he’s Batman

Edit: Morphine, clotting bandage, adrenaline, in that order though. In case you decide to be Batman.
