[Cementless fixation in endoprosthetics].
Prostheses have been fixed to the skeleton with polymethylmethacrylate for some 30 years. Many of these prostheses have failed with time, and failure has been blamed on the use of polymethylmethacrylate. Methods of fixing endoprostheses without cement have been developed in recent years. It is argued in this paper that the most important precondition for fixation is stable press-fit of the implant. Other methods of supplementary fixation, such as porous ingrowth, have been developed. However, there is little evidence to suggest that this ingrowth improves the immediate clinical result, if it occurs at all.
