An orthopaedic implant is provided for the treatment of avascular necrosis of the bone. The orthopaedic implant includes a hollow support structure and a synthetic vascular graft. The support structure defines a passageway and includes a proximal opening and a distal opening. The synthetic vascular graft is received, at least in part, within the passageway such that a proximal end portion of the synthetic vascular graft is received through the proximal opening of the support structure and a distal end portion of the synthetic vascular graft is received through the distal opening of the support structure.
