Claim:
A prosthetic hip, comprising: a socket having an outer surface; a mount on said outer surface, said mount defining a joint axis, said mount being positioned on said surface such that said joint axis substantially coincides with the natural axis of rotation of the patient's natural leg when rotated in a sagittal plane; and a first member adjustably affixed to said outer surface, said first member including a stop member; a prosthetic leg having an upper leg end wherein the upper leg end is pivotably mounted on said mount and includes a load arm extending medially from the upper leg end so as to engage the outer surface of the socket such that the prosthetic leg is pivotable about said joint axis and pivoting of the leg in at least one direction is limited by said stop member; wherein said load arm is configured so as to transmit a load from the socket directly to the prosthetic leg and includes a roller at its distal end and wherein said roller engages the outer surface of said socket.
