Fixation principles in total hip arthroplasty: Part 2 Acetabular component

In this review the different anchorage concepts of cemented and cementless acetabular components are presented and clinical long-term results - if ava ilable - are discussed. Despite numerous design improvements and modificati ons the long-term durability of acetabular components remains a major conce rn with results being clearly inferior than achieved with femoral component s. Until valid, prospective long-term success is proven for cementless desi gns cemented acetabular fixation using modern cementing technique must be r egarded as standard treatment. However, successful fixation over 15-20 year s very much depends on the quality of operative and cementing technique. So me cementless systems appear easier to use and have been documented to offe r reliable mid-term survival rates. In young patients cementless devices ha ve been well established and for some systems promising 10-year results hav e been published.
