Fixation principles in total hip arthroplasty. Part 1: Femoral component

Total hip replacement is one of the most successful procedures in surgery. In Germany there is a great variety of cemented and uncemented implants wit h different principles of fixation. We reviewed the different princip- les, with particular reference to long-term clinical outcome,and discuss the mo st popular systems available in Germany. Despite many new developments whic h have been made in the field of cementless hip replacement, cemented total hip arthroplasty will remain the "gold standard" until prospective long-te rm data (>15 years) of cementless systems become available.
