       | Could this allow for someone to have an advantage? I was reading
       | Conor McGregor may have a slight advantage after breaking his leg
       | due to a new special type of rod they attached to his leg that
       | may make it more resistant to breaking.

         | increase bone density in those regards.

           | It is common for practitioners of Muai Thai and other
           | kickboxing styles to harden their shins by whacking them with
           | hard objects, or rolling something hard like a bottle across
           | the bone. Sparring and hitting the heavy bag also harden your
           | bones over time.
           | 
           | Kicks are normally blocked with the lower leg in Muai Thai.
           | This often results in shin-on-shin contact which can be very
           | painful for both fighters. So the point isn't so much to
           | prevent full bone breaks (which are very rare) as to toughen
           | the bone enough to handle this abuse... and make sure it
           | hurts more for the other guy than it does for you.

         | with like the brutal pain a leg kick causes. I don't know, I
         | think that might just be people min maxing a little too much.

           | Yeah, it would be a small advantage at best. Leg kicks very
           | rarely break bones, usually they rely on causing pain and
           | damage to tissue. And surgery will result in lost training
           | time, plus the risk of something going wrong long term...

               | like in some cases, it isn't "the same", it's actually
               | better.

               | To be fair there are differences in condition when
               | someone 50/60/70+ gets a hip replaced and someone in
               | their prime having it. The former will have had decades
               | more wear and tear and overall degradation on their
               | joints that the latter will not yet have had. The distant
               | memories of what their hips were like may be faint enough
               | they don't even really recall whether its better or not.
               | 
               | Anecdotally I've also met older folks who expressed
               | wishing they'd done it sooner for knee/hip replacements.
               | I also have a friend with a health issue that required
               | both hips replaced at 25, and they expressed frustration
               | at the recuperation and physical therapy process, and
               | they dread the fact that they're young enough for the hip
               | replacements to need replaced themselves in a few
               | decades, an issue the older recipients generally don't
               | have to worry about.
               | 
               | Anyway, that's just a long way in saying, "Do we have
               | bionic hip implants 125% better than natural that anyone
               | with means should get if they want?" and the answer being
               | "Not yet"

               | You've hit the nail on the head. I also have a childhood
               | hip condition (Perthes disease) that has had me looking
               | at hip replacements since my 20's and having the same
               | fears as your friend.
               | 
               | Looking at pro athletes is sort of instructive;
               | essentially none of them have returned to play after a
               | hip replacement (Bo Jackson kind of, but in limited
               | capacity). A few, most famously Andy Murray, have
               | returned after hip resurfacing, so it's probably about as
               | close to a natural hip as possible, but likely still a
               | bit inferior.

               | In general a doctor is going to recommend and proceed
               | with a hip replacement because it has been proven to have
               | a positive outcome on quality of life, even considering
               | the risks associated with surgery.
               | 
               | Someone getting a hip replacement is getting one because
               | their existing hip is substantially impaired.
               | 
               | Yes it's better than their situation immediately before
               | the surgery. It's probably not better than when they were
               | thirty.

               | You're neglecting that those old hips have degraded. They
               | don't mean they wish they got a hip replacement at 30

               | Compared to a broken hip, literally anything is better.
               | Compared to a healthy hip, a replacement is _always_
               | worse.
               | 
               | Which is the precise reason we only do joint replacements
               | _after_ the joint is beyond repair. We don 't do hip
               | replacements on healthy 28 year old marathon runners. To
               | do so would markedly reduce their quality of life in both
               | the long and short term.
               | 
               | Again, most orthopedic patients will tell you that a
               | replaced or repaired joint is never the same as it was
               | when it was healthy. But living with such a damaged joint
               | is so incredibly painful and difficult that anyone would
               | choose surgery every time.
               | 
               | If your daily life is 9/10 pain, a 3/10 seems like a
               | godsend. If you live your life with _no_ pain, opting for
               | surgery that leaves you with 3 /10 for the rest of your
               | life is a pretty bad decision.
