A knee brace which allows the same bolster pad to be used for either the right or left leg, is adjustable to compensate for the differing angle between men and women and allows individual adjustment for each patients comfort and brace rotation for proper fit and joint alignment. These characteristics are obtained by a contoured bolster that is selectively mountable at various positions on either side of the shin cross piece depending on whether the brace is for the left or right leg, the bolster always being on the medial side of the shin to contact the flat section on the front of the shin thereby minimizing unwanted rotation of the brace. The bolster pad has a front face with a curvature matched to a curvature of an inner side of the cross piece and a flat on a rear side to contact the front of the shin.
