Not a problem. Apparently, it was Futuro brand. We also had to get a back brace for him at some point and they had his size, and that's something I found at Walgreens. The thigh wrap was what we had to get at a med supply place, so if all else fails something like that should do you ok. I've had knee braces from them that are adjustable, top and bottom velcro and then a third adjustable section over the knee cap, but it was stiff and not something to run in, so likely you won't need something that reinforced.
You can find what there is out there on their web site and then look around to see who has it. Good luck.
btw... your jewelry rocks. I might have to get me some of that.
