A patellar brace is a knee brace designed to stabilise or protect the kneecap.

The common brace for patellar (kneecap) instability is the 'do-nut' type, with a cut-out for the patella, and firm support to either side. There are also 'strap' braces which go around the top of the shin over the patellar tendon - for patellar tendinitis.
