Abstract
Special attention should be drawn on endoprosthetic hip replacement in young and obese
patients because of an increased risk of perioperative complications and early implant
failure. Gain of function and reduction of pain are not compromised in these patients,
so that the indication criteria remain unchanged. Implant survival is reduced in very
young patients and mainly influenced by the bearing materials. The risk of implant
malalignment, specifically of the cup, can be minimized by an intraoperative X-ray
control. The effect of bariatric surgery on perioperative complications remains unclear.
But a preoperatively uncontrolled diabetes increases the risk of infection. Known
specific risk factors of young and obese patients should be considered during the
perioperative management and be included in the individual operation planning and
informed consent.
