Knee joint mechanism for knee disarticulation prosthesis

An improved four-bar knee joint mechanism for use in knee disarticulation prosthesis is shown, including a coupler link forming a negative angle with the horizontal when said knee joint mechanism is in its stance position, an anterior link, a fixed link in a horizontal position when said knee joint is in the extended or stance position, and a posterior link, the dimensions of the links and the angle the coupler link makes with the horizontal being chosen to optimize the instant center of the mechanism.
