It will be totally worth it. He can ride and hike with no problem ... but skiing? UH UH. The brace completely stabilizes him.I've been prescribed a Don Joy that will be fitted to me. I'm guessing it's similar to that one. Thanks for sharing that! It's encouraging that even though he has no stability without it, it helps him immensely while skiing. I still have quite a lot of stability in the knee, hence my ability to hike and mountain bike and ski since the initial injury. Now, I have to wait several weeks for the brace! Gah! I guess I should be glad ski season is taking its time getting here?
