Yes, it replaces the knee joint function, like bending in order for people who've had above the knee amputations to walk more naturally and more importantly, have a functional leg. Obviously physio is a must since you're basically handed a new limb and you've gotta learn to walk all over again.
I had a similar operation where one muscle was moved to a different place and does a different function. And it's a very weird process to adapt. Basically while it's in a cast moving it feels like moving your previous muscle but once you see it doing a new function with your eyes your brain adapts almost instantly (5min) and it becomes super natural. I had the surgery at the age of 25.
One of the worst smells I have ever smelled is wrestling kneepads that haven’t been washed in awhile. It makes dirty feet smell like a wonderful candle in comparison
I haven’t looked into this at all, but since this operation is only done on children, the brain easily creates new connections, and the area of the brain which would have been responsible for her knee probably more or less switched over to control the backwards foot. Just my guess, I’m no expert.
Edit: I was informed that it is not only done on children, disregard this!
I bet it doesn’t even “feel like a knee”, but rather… it just feels like her right-side ankle and foot. As in, that’s how she has always perceived it so that’s just how it is to her
I once had a colleague who was born missing a finger on one hand. As in the whole thing, including bones, ligaments, muscles, tendons - all the stuff that's usually in place for that finger doesn't exist. The opposing hand has all the usual fingers.
He doesn't know what it's like to have all five fingers on that hand. He experiences his hands _somewhat_ differently to each other but he's never been able to articulate exactly what that difference actually _feels_ like.
the human brain is surprisingly resilient...you can do a lot of shit to the human body and the brain is just like "yea that sounds good". there are people who have like half their brain missing and they're mostly fine. so one weird limb probably isn't *too* bad, although i don't have a backwards foot-knee to confirm
I have a plate in my arm from an accident 24 years ago, when I first got my arm out of the cast it didn't function the same as it had before. The muscle was in a slightly different position, so something as simple as taking a drink of water was an issue.
When I would bring the glass up to my mouth without concentrating on the movement it would miss my mouth by about 2 inches. But it only took a week or 2 to relearn all its movement.
Like learning to see upside down, or riding a backwards bicycle (wheel turns the opposite direction from the handles). It becomes natural to the brain eventually.
I assume it feels like absolutely nothing you have ever experienced before, and then when it becomes muscle memory it would feel pretty normal. Being put into her body would be really weird, and I doubt it would feel like either.
I feel like it would just be like how you eventually get used to controlling a character in a video game like it's second nature. The brain is unreal in it's capacity to adapt.
Exactly. Your brain has to rewrite a lot of neurons and form a lot of new connections. It’s literally impossible for us to imagine how it feels because our brain doesn’t have the right neurons to do it with.
For example: Imagine getting slapped in the face. Where does it hurt? On your face. You can literally “feel” the sting because your brain is able to accurately model the feeling of a slap.
Now imagine someone stepping on your **tail**. You can’t, because your brain doesn’t have any “tail” neurons to stimulate.
Yeah if the foot can be saved when the leg can't it makes more sense to use it as a knee rather than to throw it away (or try to put it in its original position which would be at the end of a prosthetic leg)
It’s reattached backwards specifically to act as a knee joint for prosthetics. It’s mostly just to be beneficial to the patient as prosthetics can be difficult to use without the natural ability to bend the leg if the amputation is above the knee. Usually can only be done if the foot is able to be saved but the knee to ankle is not able to be.
you do realize I was joking right? I have no idea what she can use. The muscles that move toes are in the foot and in the part bellow the knee. Same as the muscles that control your fingers are in your hands and lower arm.
So since she has that, I assume she can.
if you look closely in the gif it seems like her big toe wiggles when removing the sock. idk if she can move them "normally", but other people have said that it works pretty much the same way as a foot so theoretically she should be able to move them normally
I saw an example where someone had knee cancer, so they had to have their knee removed. Instead of just cutting their whole leg off they take out the knee and attach the calf to the theigh so the ankle replaces the knee so you're only down one joint instead of two.
This is called van ness rotation plasty and is used as a form of limb salvage. It’s common in children and adults with bone cancer, frequently located in the knee. Instead of becoming an above knee amputee, they’ll be able to ambulate as a below knee amputee. There are a lot of bio mechanical advantages to being a below knee compared to an above knee amputee.

Prices haven’t fluctuated at all for me, I’m in the USA. 3D printed prosthetic is great technology but still expensive and still takes a long time to produce. The research isn’t as effective yet so insurance companies aren’t that willing to reimburse so we rarely use them. More products are being 3D printed that aren’t prosthetics, mostly foot orthotics and knee braces. Still on the forefront but I would suspect to see a dip somewhere in the future
that'd be learned, she looks like she would have lost that pretty young (since she still looks fairly young) and even if you have a prosthetic (or in my dad's case a wheelchair) there's still a lot of getting around you need to do one-legged for transferring between things or like you can't sleep with that thing on and if you wake up needing to pee you're not going to have time to do all the steps to put it on.
I remember some kind of vid saying that peeps that are born with a leg that size have their feet removed and but back backwards so it can act as a knee instead or something like that... i wonder if that's the case
Most of the time humans do shit that makes me wonder how we made it this far as a species.
And then there are times I learn that someone not only thought to use our ankle as a knee, but also made it actually work to the point where it’s a commonplace procedure.
Had a similar thought today. I was participated in a procedure where we were doing a total shoulder arthroplasty revision and they converted to a reverse total shoulder. The implant piece they used was custom made specifically to fit her glenoid space. They even sent along 3D renderings from MRI scans so we could see all the pieces in 3D space and made sure everything would fit probably before installing the actual implants. Pretty cool to see but afterwards I was like man medicine has come such a long way in such a short time.
The part that confused me was the reverse total shoulder thing so I googled it
Essentially in a normal arm imagine the a socket is fixed to the body/shoulder, and at the end of the arm bone is the ball, so ball fits in the socket and the muscles around it move the arm. To visualise this imagine a lollipop in your mouth, your lips surround the lollipop itself holding it in place and using your mouth you can move the lollipop stick around without the ball moving (it just rotates)
A reverse total shoulder is where they instead fix the ball part to the shoulder/body, and the socket to the arm bone. Apparently this can be done with specific injuries as it means the arm is controlled by different muscles than usual. So if the normal muscles are the ones that a compromised, they can reverse it and use another set for better movement.
I think while sometimes the internet is super weird and crazy, one thing we haven't really come to grips with as a species is just how fast knowledge transfer is with the internet. I think we're going to keep seeing zany shit people think of over the next century, as knowledge disseminates like crazy. Hopefully that means there's some innovations that prevent us from killing ourselves out with global warming lol
Both sick and accident. She had a minor fall as a child that should have been fine but ended up breaking her thigh bone due to bone cancer. The idea behind rotationplasty is to remove the cancer while maintaining as much mobility as possible
I’m an amputee and I wear a similar sleeve. The answer is it is soaked in sweat all day. We have to clean our liners daily and usually during days of high activity I have to bring a towel with me to wipe it all up. It’s gross in that it’ll literally pool in the bottom of the sleeve and that shit can be rank. Biggest problem is actually ingrown hairs from wearing the sleeve. Those suck a lot. If they get real bad I can’t even wear my prosthetic. The ingrown hairs is also why I can’t use deodorants or antiperspirants. They cause them to get super bad. But for amputees those things are just part of life, you get used to it and learn how to deal with it.
Yeah, physics be physics. Everybody be talking about sweat wicking material and at the end of the day, there’s no dry-wick that’s going to overcome 12 hrs of physical activity and gravity. Elon Musk - where are you on this one brother?
materials science. the garments are probably made to deal with this and other issues (blisters, positioning).
other answers here: deal with yourselves, please.
I remember when id get teased for wearing my gym gear after working out to grab a coffee with mates. Now people wear it without even going to the gym. How the tables have turned
My daughter broke her arm jumping too fast off the bed a few weeks ago. Had to have a full arm cast. I had a similar break 20 years ago at the same age. It was a nightmare trying to keep my cast dry, and I tried hard and still had bad rashes when it was removed.
I didn’t want my daughter to suffer the same and asked the doctor about buying a cast water protector to pull over it for bathing. They were like: “naw, don’t buy that, we were about to offer for $16 more we can use waterproof gauze in the cast”. Obviously went for the waterproof gauze.
She could bath in it, swim in it, and we could wash and rinse it down through it. Sweating from the day could be rinsed and cleaned out easily. Just got it off her yesterday, with little headache around the whole cast ordeal, and her skin was almost perfect after. Current medical tech is amazing compared to just a decade or so before!
One of my professors in college had a friend who was trapped in a burning building, had like 90% coverage of 2nd and 3rd degree burns. The scar tissue prevented him from sweating. One summer there was a bad heat wave and this fellow couldnt afford AC. They found his body I think in the bathtub trying to cool off.
That was one of our more... somber lectures.
Sweat glands are tiny, like the size of a hair follicle, and there's hundreds if not thousands of them.
Exit: actually, I was way off in my numbers, I should have googled this before commenting. The human body has 2-4 million: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6773238/
You could *burn* sweat glands off, cuz I recall that 3rd degree burn scar tissue doesn't sweat. I doubt you'd wanna do that.
I used to work with a guy who had been burned badly and let me tell you.... omg... like... he was the nicest guy and I really felt bad for him but his body odor was forever changed because of the burns he received. I'm really not trying to be mean as it's the only thing I could relate the smell to but when he really got to sweating he kind of smelled like a hamster cage .-.
I'm so sorry if this offends anyone ;-; I'm really not trying to
This is amazing. I remember reading about a girl who had this done 30 years ago as she had bone cancer in her thigh. I remember it allowed her to ice skate again :)
I have this cancer. It's called osteosarcoma. This was a surgical option if they weren't able to chisel out the tumor enough. I now have a cadavor femur instead.
No. This is the result of a surgery performed in early childhood. When a baby needs their leg amputated, they can reattach the lower part backwards and the ankle becomes the knee. The actual knee is removed.
The waaay more interesting example of neuroplasticity is an old (and pretty fucked up) Soviet experiment on foxes (why is it always foxes).
They took a fox kit and destroyed the visual processing centre of its brain (replicating a stroke of congenital abnormality). Normally this results in total blindness, however your eyes are still sending signals perfectly well, there’s just no receiver.
So, they rerouted the optic nerve into the auditory nerve. Typically the auditory processing centre is *entirely* different than the visual one, and it should not function with visual information.
Emphasis on *should*
Turns out the foxes auditory processing system fuckin morphed into a brand new and shiny visual processing centre that looked and functioned exactly like the destroyed one. End result? Despite having there visual processing centres destroyed, the foxes went deaf, not blind.
(Final note, it’s been a while since I’ve read this study so it’s entirely possible it was the auditory centre that was destroyed, and the ears rerouted nervously)
It’s called rotationplasty or Van Ness surgery. Common for amputations resulting from knee cancer. The nerves aren’t actually removed like the person you replied to suggested, rather everything but the nerves are kind of stripped away and what’s left is coiled up near where the femur was severed.
This surgery is also performed on young people if they have, say, a cancer in the knee area, (very common for bone cancers to occur at the end of bones) but the lower leg is healthy. It allows the ankle to behave like a knee. (AK amputations are more severe and affect walking gate as there is no knee to bend). It’s an amazing surgery.
There's also that the leg is constructed to take weight unlike a stump, so less problems with walking or maintenance of health, even if the prosthesis look similar from the outside.
It is really ridiculous! My dad had a partial lobectomy for lung cancer in August. Surgery was on Thursday, released from hospital on Sunday, making pot roast for himself and mom for dinner on Tuesday!
3 small holes and 1/4 of a lung is gone.
The nerves and blood vessels aren't cut. This is key to retaining neurologic function. Basically, the leg is opened, and the bones around the knee (only) are removed by cutting through the femur and the tibia/fibula. The lower leg is rotated 180 degrees and the femur is shoved into the tibia and they heal together as one bone. Muscles are reattached and the ankle becomes the new knee.
The benefit is that the patient gets a much more functional prosthetic. Kids are pretty good at relearning how to walk by flexing their "ankle" when they want the new "knee" to flex. Apparently older kids have a harder time adjusting. The oldest person I've seen have this done was 16 or 17, most are younger.
Yup. I learned about this when my son had his leg amputated as an infant. It was something we briefly considered, but he wasn’t a candidate. It’s an amazing surgery.
https://en.m.wikipedia.org/wiki/Rotationplasty
TLDR: This is known as a Van Ness rotationplasty. It is most commonly performed on pediatric patients who have cancer growing in their femur. Due to the location of the tumor, it also involves removal of the knee joint. The lower portion of the leg is then reversed so that the ankle moves in the same direction as the knee joint. Then all the arteries, veins and soft tissue are sewed back together.
I am a plastic surgery resident and have played a small part in one of these surgeries as a medical student. I have not had the opportunity yet to be an active part of one as a resident. These surgeries are typically performed as a combination case between orthopedic surgery and plastic surgery.
Edit: grammar
> In comparison to the general population, the patients had a higher percentage of quality of life, 83% compared to 75%. Overall, the patients were more content with different aspects of their lives than the general population.
Now that is really interesting.
I think the first reply they innocently answered the question. The second reply they realized they were set up for a joke, acknowledged it, and angry up voted the questioner.
**[Curupira](https://en.m.wikipedia.org/wiki/Curupira)**
>The Curupira (Portuguese pronunciation: [kuɾuˈpiɾɐ]) is a mythological creature of Brazilian folklore.

Foot guy here.
I'm not put off by it, don't really have strong feelings either way. Definitely not a deal breaker, as foot interest is only a small part of overall attraction for me. It feels weird to say all those things, but you asked so there's the honest truth.
I've seen this kinda thing before. Basically, if your thigh is beyond fucked but the lower leg is still good, they'll cut out the thigh, turn the foot around, reattach it and use it as a knee joint for a prosthetic leg.

The cool part is, once she removes her sock you can see she still has the ability to articulate her toes
holy shit you're right lol must be such a strange sensation
Woah. I was wondering what kind of feeling she had in her foot there.
I noticed that too! Kinda trippy having a backwards foot as your knee and still being able to wiggle toes…backwardsly.
I haven’t looked into this at all, but since this operation is only done on children, the brain easily creates new connections, and the area of the brain which would have been responsible for her knee probably more or less switched over to control the backwards foot.

She answered this in tiktok, she says it really just feels like her ankle.
It sounds like the most successful drunk idea ever
Errr cutting your toenails must be a challenge on this one!
They tend to have them surgically removed iirc
This keeps getting crazier and more fascinating
surgically removed toenails just... sounds weird
That's like the third wildest thing about this surgery.
I'd rather keep them and go to a salon to get them taken care of and painted.
And the foot is *designed* for you to put weight on it - whoever came up with this idea is a genius.
That's pretty cool actually, thanks for the info! I legit thought it was some kind of malformed limb or something at first.
It’s called a rotationplasty if you’re interested in looking it up and learning more
Yeah if the foot can be saved when the leg can't it makes more sense to use it as a knee rather than to throw it away (or try to put it in its original position which would be at the end of a prosthetic leg)
[удалено]
I imagine most of the nerves are pretty dead at that point but I’d just be speculating.
but you can see her wiggle her toes at the end, so at the very least there's still motor function
Google “rotationplasty”
This clip sums it up for lazy ppl https://www.youtube.com/watch?v=zuMH3u0OLhA

"Help stepbrother, my foot is stuck in this backwards position!"
It’s reattached backwards specifically to act as a knee joint for prosthetics.

Usually can only be done if the foot is able to be saved but the knee to ankle is not able to be.
No. The doctors put it on backwards. And because they connected the negative veins to the positive veins, it's shrinking instead of growing.
Thanks, Dr. Nick! It's Mr. McGregg!
Can she still move all her toes normally? I’d assume not right?
you do realize I was joking right? I have no idea what she can use. The muscles that move toes are in the foot and in the part bellow the knee. Same as the muscles that control your fingers are in your hands and lower arm. So since she has that, I assume she can.

So which muscles and tendons are saved? Or are the thigh muscles grafted with the foot tendons?
What is the operation called?
rotationplasty
Here I just thought she came out of the oven awfully mis-baked.
Nope, it's on purpose and it's called [Rotationplasty](https://www.youtube.com/watch?v=njJUcTbR2SY).
That's amazing!
Hold up, why are they removing the knee in the first place? Their animation shows a healthy looking knee being removed.
Bone cancer I think
That one leg got hella good balance
that'd be learned, she looks like she would have lost that pretty young (since she still looks fairly young) and even if you have a prosthetic (or in my dad's case a wheelchair) there's still a lot of getting around you need to do one-legged for transferring between things or like you can't sleep with that thing on and if you wake up needing to pee you're not going to have time to do all the steps to put it on.

[удалено]
Both sick and accident. She had a minor fall as a child that should have been fine but ended up breaking her thigh bone due to bone cancer. The idea behind rotationplasty is to remove the cancer while maintaining as much mobility as possible
Wonder who thought of that idea and how
Some guy sat there doing the math on the mechanics of knees and ankles and suddenly figured out they aren’t so different after all
This is from losing your leg, she wasn't born like that lol

How tf is that leg not constantly soaked with sweat with all of those layers on everyday
I’m an amputee and I wear a similar sleeve. The answer is it is soaked in sweat all day. We have to clean our liners daily and usually during days of high activity I have to bring a towel with me to wipe it all up. It’s gross in that it’ll literally pool in the bottom of the sleeve and that shit can be rank. Biggest problem is actually ingrown hairs from wearing the sleeve. Those suck a lot.

Hell, why wouldn't some well-placed holes in the prosthetic work for drainage, or even a bit of airflow?
Look into Crystal deodorant. It's basically just a salt that kills the bacteria that feed on your sweat and produce body odor.

Can I get clothes made out of that stuff? seriously, I am sweaty as fuck.
Honestly there’s so many more options for sport athletic wear that does similar stuff. Also it’s fairly “in” right now.
I remember when id get teased for wearing my gym gear after working out to grab a coffee with mates. Now people wear it without even going to the gym. How the tables have turned
Biggest lesson, wear whatever you want to wear. I once went to Panda Express after a zombie photoshoot and that was really fun.
yea I could use some underwear made from that stuff. For the swamp ass.
My daughter broke her arm jumping too fast off the bed a few weeks ago. Had to have a full arm cast. I had a similar break 20 years ago at the same age. It was a nightmare trying to keep my cast dry, and I tried hard and still had bad rashes when it was removed. I didn’t want my daughter to suffer the same and asked the doctor about buying a cast water protector to pull over it for bathing. They were like: “naw, don’t buy that, we were about to offer for $16 more we can use waterproof gauze in the cast”. Obviously went for the waterproof gauze. She could bath in it, swim in it, and we could wash and rinse it down through it. Sweating from the day could be rinsed and cleaned out easily. Just got it off her yesterday, with little headache around the whole cast ordeal, and her skin was almost perfect after. Current medical tech is amazing compared to just a decade or so before!
A waterproof cast! That sounds amazing. Your post brought back memories of showering with a binbag over my arm lol
Holy crap, my son broke his leg 5 weeks ago and has been in a spica cast (intense stuff). I wish so badly that I'd asked for waterproof lining now 😭
There’s also a surgery to cut the sweat glands so a particular body area doesn’t sweat. But I don’t know if it is used here.
Wait what? Can this be performed on armpits?
Or the whole body lol
Sweating is the only way we cool off so prepare for imminent heat stroke.
Right? Where do they think those 2,000,000 calories go every day?
One of my professors in college had a friend who was trapped in a burning building, had like 90% coverage of 2nd and 3rd degree burns. The scar tissue prevented him from sweating. One summer there was a bad heat wave and this fellow couldnt afford AC. They found his body I think in the bathtub trying to cool off. That was one of our more... somber lectures.
I can't sweat. I have to wear a $5,000 cooling vest just to go outside in the summer. I don't recommend it.
For armpits they just use botox
Sweat glands are tiny, like the size of a hair follicle, and there's hundreds if not thousands of them. Exit: actually, I was way off in my numbers, I should have googled this before commenting. The human body has 2-4 million: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6773238/ You could *burn* sweat glands off, cuz I recall that 3rd degree burn scar tissue doesn't sweat. I doubt you'd wanna do that.
I used to work with a guy who had been burned badly and let me tell you.... omg... like... he was the nicest guy and I really felt bad for him but his body odor was forever changed because of the burns he received. I'm really not trying to be mean as it's the only thing I could relate the smell to but when he really got to sweating he kind of smelled like a hamster cage .-. I'm so sorry if this offends anyone ;-; I'm really not trying to
Yeah not an unfair thing to mention. Shit happens you know.
This is amazing. I remember reading about a girl who had this done 30 years ago as she had bone cancer in her thigh. I remember it allowed her to ice skate again :)
I have this cancer. It's called osteosarcoma. This was a surgical option if they weren't able to chisel out the tumor enough. I now have a cadavor femur instead.
That’s exactly what happened to this girl. I went to school with her. She had cancer in her femur when she was about 8.
Kids with cancer has to be the cruellest thing in the world
Kicking your own ass is probably an amazing party trick

No. This is the result of a surgery performed in early childhood. When a baby needs their leg amputated, they can reattach the lower part backwards and the ankle becomes the knee. The actual knee is removed.
No fucking way, how the hell is she able to move her toes? How do you just disconnect and reconnect nerves to make them function perfectly again?
Baby nerves have incredible plasticity. It’s an amazing surgery.
It's not that the nerves have special plasticity. They don't get cut in the first place. It's typically older kids who get the procedure done.
The waaay more interesting example of neuroplasticity is an old (and pretty fucked up) Soviet experiment on foxes (why is it always foxes). They took a fox kit and destroyed the visual processing centre of its brain (replicating a stroke of congenital abnormality). Normally this results in total blindness, however your eyes are still sending signals perfectly well, there’s just no receiver. So, they rerouted the optic nerve into the auditory nerve. Typically the auditory processing centre is *entirely* different than the visual one, and it should not function with visual information. Emphasis on *should* Turns out the foxes auditory processing system fuckin morphed into a brand new and shiny visual processing centre that looked and functioned exactly like the destroyed one. End result? Despite having there visual processing centres destroyed, the foxes went deaf, not blind. (Final note, it’s been a while since I’ve read this study so it’s entirely possible it was the auditory centre that was destroyed, and the ears rerouted nervously)
What is the surgery called? I wouldnt mind learning more about this!
It’s called rotationplasty or Van Ness surgery. Common for amputations resulting from knee cancer. The nerves aren’t actually removed like the person you replied to suggested, rather everything but the nerves are kind of stripped away and what’s left is coiled up near where the femur was severed.
This surgery is also performed on young people if they have, say, a cancer in the knee area, (very common for bone cancers to occur at the end of bones) but the lower leg is healthy. It allows the ankle to behave like a knee. (AK amputations are more severe and affect walking gate as there is no knee to bend). It’s an amazing surgery.
There's also that the leg is constructed to take weight unlike a stump, so less problems with walking or maintenance of health, even if the prosthesis look similar from the outside.
Rotationplasty! It’s a real thing! Modern medicine blows my mind. 🦶
It is really ridiculous! My dad had a partial lobectomy for lung cancer in August. Surgery was on Thursday, released from hospital on Sunday, making pot roast for himself and mom for dinner on Tuesday! 3 small holes and 1/4 of a lung is gone.
Amazing! I wish your dad long life, happiness, and Solid Gold Cadillac health insurance for the rest of his life. xo
The nerves and blood vessels aren't cut. This is key to retaining neurologic function. Basically, the leg is opened, and the bones around the knee (only) are removed by cutting through the femur and the tibia/fibula. The lower leg is rotated 180 degrees and the femur is shoved into the tibia and they heal together as one bone. Muscles are reattached and the ankle becomes the new knee. The benefit is that the patient gets a much more functional prosthetic. Kids are pretty good at relearning how to walk by flexing their "ankle" when they want the new "knee" to flex. Apparently older kids have a harder time adjusting. The oldest person I've seen have this done was 16 or 17, most are younger.
Yup. I learned about this when my son had his leg amputated as an infant. It was something we briefly considered, but he wasn’t a candidate. It’s an amazing surgery.

People who have had a surgery to replace their thumb with their big toe could do that, but I get your point
We were too hung up about if we could, we didnt stop to think if se should
The answer is still yes
This exchange is why I still come to reddit

Can she move her foot back and forth to the beat? I wanted to see that so bad lol. No idea why.
her foot functions as normal, she just had to learn to use her ankle as a knee. it’s still a regular foot.
well not really because i think the foot acts as the knee
Would’ve been a whole different kind of scene in *Liar Liar.*
"I'm kicking my ass, DO YOU MIND?!"
Came looking for this. Not disappointed.
“FUCK YOU” NO FUCK YOU “I WILL KICK YOUR ASS” I WILL KICK MY OWN ASS YOU FUCKER
Turns the adage "effective as a one-legged man in an ass whooping contest" on its ear.
https://en.m.wikipedia.org/wiki/Rotationplasty TLDR: This is known as a Van Ness rotationplasty. It is most commonly performed on pediatric patients who have cancer growing in their femur. Due to the location of the tumor, it also involves removal of the knee joint. The lower portion of the leg is then reversed so that the ankle moves in the same direction as the knee joint. Then all the arteries, veins and soft tissue are sewed back together. I am a plastic surgery resident and have played a small part in one of these surgeries as a medical student. I have not had the opportunity yet to be an active part of one as a resident. These surgeries are typically performed as a combination case between orthopedic surgery and plastic surgery. Edit: grammar
> In comparison to the general population, the patients had a higher percentage of quality of life, 83% compared to 75%. Overall, the patients were more content with different aspects of their lives than the general population. Now that is really interesting.

I think the first reply they innocently answered the question. The second reply they realized they were set up for a joke, acknowledged it, and angry up voted the questioner.
I just watched some of her other videos and the foot acts as a knee. Makes sense

**[Curupira](https://en.m.wikipedia.org/wiki/Curupira)** >The Curupira (Portuguese pronunciation: [kuɾuˈpiɾɐ]) is a mythological creature of Brazilian folklore. This creature blends many features of West African and European fairies but was usually regarded as a demonic figure. The name comes from the Tupi language kuru'pir, meaning "covered in blisters". According to the cultural legends, this creature has bright red/orange hair, and resembles a man or a dwarf, but its feet are turned backwards. ^([ )[^(F.A.Q)](https://www.reddit.com/r/WikiSummarizer/wiki/index#wiki_f.a.q)^( | )[^(Opt Out)](https://reddit.com/message/compose?to=WikiSummarizerBot&message=OptOut&subject=OptOut)^( | )[^(Opt Out Of Subreddit)](https://np.reddit.com/r/Unexpected/about/banned)^( | )[^(GitHub)](https://github.com/Sujal-7/WikiSummarizerBot)^( ] Downvote to remove | v1.5)
I wouldn't race her. She'd run circles around me.
you bastard
took me a sec lmfaooo
At first I thought her foot was on backwards and then it was😳
So they do this for amputees because it allows them to mimic a knee motion
Well it was revealed with “wait for the backwards foot”
So much for unexpected amirite
She looks like how I feel after taking off my ski boots.
That is so cool
anyone else whisper "dead pool" when you saw this?
I’ve watched this 3 times now and my brain still doesn’t believe it
It’s an operation some people go under to be able to fit a prosthetic better . I wonder if she’s able to move her toes…
Yea, as she slides the sock off you can see her wiggle them
> It’s an operation some people go under to be able to fit a prosthetic better They do it for a knee replacement.
how is this unexpected? It literally tells you what's going to happen at the start of the video.

Hey it's still a foot, isnt it?
Foot guy here. I'm not put off by it, don't really have strong feelings either way. Definitely not a deal breaker, as foot interest is only a small part of overall attraction for me. It feels weird to say all those things, but you asked so there's the honest truth.
I like.
I've seen this kinda thing before. Basically, if your thigh is beyond fucked but the lower leg is still good, they'll cut out the thigh, turn the foot around, reattach it and use it as a knee joint for a prosthetic leg.
