A patella cup for use with a knee brace includes a main shell secured to a padded liner, and an upper shell disposed above the main shell, and secured at one end to the padded liner. The upper shell may include an extension passing under an upper end of the main shell, so that the upper shell is bendable rearwardly relative to the main shell. A lower strap and at least one upper strap are secured to the padded liner, such that each strap includes an elastic portion to allow each strap to stretch in length when pulled. Loops are secured to the padded liner, on lateral and medial sides of the main shell, with the loops secured to lateral and medial hinges on either side of a knee brace used with the patella cup.
