A post-operative support apparatus for a patient's residual limb includes: a planar, stretchable and flexible wrap panel sized to wrap around an outer circumference of a patient's residual limb, along a length of the patient's residual limb, where the wrap panel includes one or more fasteners (such as hook & loop fastener components) for maintaining the wrap panel in place around the patient's residual limb; a pair of substantially rigid, elongated side support panels to respectively apply to the medial and lateral sides of the patient's residual limb, over the wrap panel; a distal cushion to apply against a distal end of the patient's residual limb; and a retainer maintaining the distal cushion against the patient's residual limb.
