The acetabulum and the shaft of the endoprosthesis have a special coating for ingrowth into the bone tissue. Modern metal-metal friction pairs in new press-fit endoprostheses are more resistant to wear, in terms of elasticity they are similar to the elasticity of human bone tissue. When carrying out such a technique, the movements between the implant and the pelvic bone are reduced, which ensures physiological movements in the joint.

The application of a titanium surface layer on the surface of implantable joints proves in practice the high resistance to wear of the articular surfaces during movements in the joint. An artificial acetabulum can be made using polyethylene, metal and ceramics. Together with prostheses of the femoral head, various “sliding” friction pairs are obtained in endoprostheses, which naturally distinguishes them in terms of resistance to abrasion, strength, service life, sensitivity to impact, i.e. Each type of arthroplasty has its own advantages and disadvantages. There are various technical models of the acetabulum, which are basically similar to each other, but in the technical development of the femoral stem implant, there are various designs and new modifications are being developed.
