Could try to do the braces, if you don't mind them as outfits (just say which whole outfit or outfit bottom you want. Both legs?). Found some at MTS2 that I converted for toddlers. Shouldn't be too hard to make some for teens
(I was going to make them for teens, but got tired of it after making I don't know how many toddler and child versions...) Not sure if I want to try making braces as accessories, though. But i have considered it.
I've made an all-age version of Rose's crutches that works with other accessories, but so far it is unfinished (some bone assignment tweaking left), and only for personal use. I' have to figure out a few things when it comes to their Terms of Use, before even considering to post them (like where to find the ToU...)
If you have a tiny bit of knowledge with SimPE, you could try tweaking the crutches yourself. There's some info about how to that
here. It's very easy
