Uncemented total hip arthroplasty has proven to be an acceptable alternative to cemented total hip arthroplasty with good short-term results. With the elimination of the use of polymethyl methacrylate for component fixation, failure at the bone-cement interface, with resultant osteolysis and progressive loosening, was thought to be preventable. Unfortunately the ultra-high-molecular-weight polyethylene acetabular insert can wear and produce particulate debris. This debris can stimulate an osteolytic reaction and lead to late aseptic loosening in a cementless total hip arthroplasty.
无骨水泥全髋关节置换术已被证明是骨水泥全髋关节置换术的一种可接受的替代方法，短期效果良好。随着用于假体固定的聚甲基丙烯酸甲酯的不再使用，骨水泥界面处的失败以及由此导致的骨溶解和渐进性松动被认为是可以预防的。不幸的是，超高分子量聚乙烯髋臼内衬会磨损并产生颗粒碎片。这种碎片会刺激骨溶解反应，并导致无骨水泥全髋关节置换术后期出现无菌性松动。
