Abstract
Abstract A single brace extends upwardly from beneath the shoe to the thigh where it extends into a pocket in the trousers of the wearer. The brace has a ball bearing joint in line with the knee joint of the wearer. The lower member of the brace is made in two parts which overlap and are rigidly secured together as by screws in selected matching holes which provide for extension or contraction of the brace to accommodate different length legs. Protective padding is provided on the brace at the ankle and thigh.
