Abstract
Abstract Knee brace of unfolding type has a wrap-on pad with quick-fasteners on opposite sides for initial pad application to a knee, and tapes for finish application of the pad to the knee, with the pad also having stays to lend it rigidity over part of its knee-enveloping expanse while permitting ready natural flexure of the braced knee.
