In the case of artificial hip joints, for example, there are currently two main types of artificial joints on the market: cemented mechanical and non-cemented biological. In the former case, the bone cement is filled between the bone and the prosthesis. The bone cement is not a real adhesive, but rather it fills the space between the prosthesis and the bone and the space in the bone to obtain the so-called filling and micro-interlocking. Thus, what is obtained with bone cement is mechanical stability. Non-cemented prostheses are biologically fixed by the close embedding of the prosthesis with a pressure fit to the bone bed and a microporous coating that brings the prosthesis surface into close contact with the bone and uses the microporosity of the prosthesis surface (40-400um) to allow bone to grow in. Cemented prostheses have little to no micromovement at the prosthesis-cement-bone interface, thus allowing early weight bearing without fear of early loosening and subsidence.
