The invention relates to a socket (1) for a hip joint endoprosthesis (2), wherein the socket (1) is made of non-aging materials and forms a low-abrasion tribological pairing with a ball (3). The socket (1) comprises an implant surface (4) formed of a material having a porous surface, wherein an isoelastic structure of the socket (1) according to the invention and the ball brings about a physiological load transmission by means of specially concepted materials, the elastic modulus of said materials being matched to the values of a spongy bone material.
