[Long-term results in hip endoprosthesis--problems, facts and outcome]

Analysis of long-term follow-up studies and of the pertinent literature leads to the conclusion, that the survival of artificial hip joints is still limited; therefore, the age of the patient is still a crucial element in the decision to operate. Also decisive for the indication are the patient's pain and suffering on the one hand and his expectations and needs on the other. A good indication can only be established by considering all these factors and weighing them against one another in a comprehensive, in-depth discussion between patient and surgeon. Other diseases are frequent in this age group and have also to be considered, as they might well affect the result. The diagnostics of implant loosening and the indications for revision are discussed.
