Currently wearing a Don Joy Defiance III for post ACL reconstruction. It's custom made and was not cheap, not that the off the shelf braces are.

Are you looking for a rigid brace (like the one I wear) or a soft brace? I worse a soft brace for a bit after injuring the ACL. It helped and I may go back to it once I am able to lose the rigid brace. It may be enough for you.

I would see a sports orthopedic doc first. If it's prescribed your insurance may pick up some of the tab. Plus, he'll know what brace to put you in. What good is the wrong brace gonna do you, right.
