title: [Current knowledge and future perspectives of cementless endoprosthetics].
abstract: The current problems facing the clinician, regarding young patients whose hips and knees have completely deteriorated, involve a return to function, as well as a longer life for the prosthesis than that rendered by cement fixation. The alternatives to cemented primary fixation devices have not yet with stood the test of time. In addition, when aseptic loosening of cemented prostheses occurs, cemented revisions have already demonstrated a high failure rate after a short-term follow-up, particularly in the hip. A follow-up period of up to 6 years for a cementless total knee and a short-term follow-up for a cementless hip (up to 3 years), using a porous metal bone contact surface, have shown very satisfactory clinical results in primary total hip and knee prostheses and revision of the total hip without the use of bone cement. These early results justify continuation of this clinical trial.
