title: Current state of cementless hip prostheses.
abstract: Cemented cups in the young patient continue to show an unacceptable rate of early aseptic loosening. A well designed cementless prosthesis, implanted with good technique, is a better alternative. With the uncertainty surrounding the femoral stem, a hybrid total hip with a cemented stem and porous ingrowth cup remains an acceptable interim solution. There is an ongoing problem with the wear debris produced by the available implant materials. There is hope that the newer materials will help in this regard. Custom made prostheses at this time, seem most suited for those hips with marked deformity making the use of standard systems difficult. The use of cement in the elderly population remains an acceptable technique with the advantages of immediate fixation and early weight bearing.
