Best knee-brace for grappling/mma

Coming off a knee injury, but feeling pretty good about getting on the mats again. Has anyone here used a brace for their knees that they can recommend?

good question

ttt 4 anyone...

 Cliff Keen Air Brace

Offered great support after dislocating my patella (and the associated tears/fractures). You can grapple and strike with it without much of an issue

Very cool! Thanks, CR!

i thank you also
