Abstract: A leg support assembly includes two bodies pivotally coupled to each other. As an example, a proximate body may be sized and shaped to be placed under the thigh when in a sitting position (e.g., below the hamstring). This proximate body may be of a length and width so as to distribute at least a portion of the lower leg's weight. Additionally, a distal body may be placed under the top of a calf such that a hinge is positioned substantially under the popliteal fossa (i.e., the small area behind the knee). Various locking mechanisms may be used to lock the planar body and the distal body in a substantially fixed angle relative to each other. The locking mechanisms may be locked and unlocked to change that angle and then lock the angle in different positions.
