It's been nearly three seasons since Arizona (Jessica Capshaw) lost her leg in the still traumatic Season 8 finale plane crash that has shaped the last few seasons of Grey's Anatomy. Although we don't often see Arizona sans leg these days, the aftereffects of what happened to her still loom large. No one who saw the Season 9 finale can forget how upset Arizona was over her injury, and the her recent breakup with Callie (Sara Ramirez) reminded us of how difficult the loss was for Arizona to bear. Also difficult? The TV magic that can make it look like Arizona really is missing a leg.

Apparently, a lot of people have wondered the same thing, but fortunately we have the answer, thanks to a tweet from Jessica Capshaw from back in Season 9. She tweeted the secret to the television magic: “In [Season 9, Episode 6: “Second Opinion”] I was walking on a prosthetic with my own leg tied behind me. [Visual effects firm] Starworks digitally erased any overlap. They are amazing!”

That does not sound comfortable, but it did look amazing! Are you surprised at how good the final product turned out? What do you think is Grey’s Anatomy’s most impressive digital effect in the show’s history?
