this is terrifying specifically because my knee has been bothering me lately….
Had my left knee replaced last August with one of these :- http://www.smith-nephew.com/professional/products/all-products/legion/genesis-ii-total-knee-replacement-system/
Made a great recovery, quality of life is now much higher. Thank you NHS 🙂
That seems terrifying. Can’t they just paste more of that Elmer’s glue looking cartilage and call if a day?
Mine is different. the spacer plate seats into the tibial component and can pivot. it’s a “mobile bearing” knee joint.
Thanks OP my knee hurts now. I think it needs replaced.
I like how it ends with “.. and then we just fuck with the patella cause why not?”
How to take care of my knee?
I’m probably going to get something like this done in about 10-15 years.
Had an injury 11 years ago that still nags on me and the doctor said I was looking at total knee replacement by the time I’m 50.
I used to make videos like this one for DePuy Synthes. Something not being shown here is how much hammering a surgeon has to do to place those implants – they don’t just slide neatly into place like that!
This gets especially interesting with things like hip and shoulder replacements, where (for example) the femur will have a lengthy (~6″) stem which needs to be hammered down inside of it.
But don’t worry – some types forego the hammer by hollowing out more of your bone and filling it with medical-grade concrete instead.
Validates that part in the movie White Chicks when she goes, “We got our knees done.”
Good to know that.
Having worked on software that was going to replace an existing process for sizing/measuring for knee implants like the one in the video I’d stay away from them as long as possible and/or look into alternatives like Mako (purchased by Stryker ~5 years ago).
The process was appalling including a step of sizing and aligning leg x-rays from the hip to the foot in Microsoft PowerPoint…. Yes PowerPoint… Scales were different for each image and just a general mess. Surgeons were often missing their bone cuts by 25° as the bone saw blade flexes.
Tldr use as a last resort and look for other options before these total knee replacements.
It’s not permanently fixed. All joint implants have an issue called stress shielding. Bone expects to experience a stress field and if the loading is not correct it will start to undergo resorbtion. The implant is far stiffer that the original bone, so the bone starts to remodel to the reduced loading it sees. Eventually the bone will crumble away. It could take decades, but this is why surgery is avoided until as late in a person’s life as possible.
Also, 3D4 medical are scumbags. I interviewed for them and have never experienced a more unprofessional company before or since.
Between this, the realities of dentistry, and watching a bunch of surgery videos with my kid (watching cancer get cleaned out of a brain is neat)…I am kind of disappointed in medical solutions to problems in general. I thought humanity had come so far, but it’s all so damn barbaric when you get into the nitty-gritty. Just a lot of chopping, grinding, and replacing with stuff that isn’t really even similar to the original material (so much metal!). We just have good enough anesthesia to act like it’s civilized.
I literally just watched a commercial on tv about kneejoints 5 seconds before scrolling down to this
By the second half I didn’t even know what to expect any more.
But how do they do this around all the blood tendons ligaments ???
I’m not so worried now, 🙂
Shameless plug time!
The company I work for is making surgery simulations. We have one for this – https://youtu.be/a2Jguv1iC7U
How murch to replace the whole leg?
Is it just me or is that drill spinning the wrong way?
I feel like that would just give me a new joint ache.
what is this procedure called?
For the low price of 125k+
Does this things sound the alarm al the airport?
When you have problems with only one side (in my case, an old knee injury that progressed into arthritis problems over time), you can do a partial knee replacement. My knee looks like [this.](https://imgur.com/a/P7tdAPQ)
It was a tough recovery, but now it works great. I hike and climb mountains and such. The only bummer is that I’m not allowed to run anymore, and I miss running.
A partial puts off the need for a full replacement typically for 10 years or more, so it’s a good thing if you’re younger like me. Knee replacements don’t last forever, so you don’t want to get one too young…
very good representation of joints
i could watch this all day <3_______<3
