Cementless revision hip arthroplasty is described as state of the art, especially in cases of advanced bone loss of the femur. A requirement for a good result from cement-free revision hip arthroplasty is classification of the bone defect and the presence of a mechanically stable anchorage in the area of the original implant or, in cases of bone defects, distal to the original area in stable diaphyseal bone. The possibility of the accumulation of autografts or allogeneic osseous grafts and the entire removal of the cement and debris has been postulated. The advantages of cementless revision hip arthroplasty include regeneration of the bone stock and the often available modularity of the revision hip system, which allows adaptation to different bone configurations and also allows a partial change of the prosthesis in rerevision cases, such as in cases of sintering or derotation. Cemented revision arthroplasty should be done only in special cases, such as with marginal bone defects or for older patients with a short life expectancy.
无骨水泥翻修髋关节置换术被描述为先进技术，尤其是在股骨严重骨量丢失的情况下。无骨水泥翻修髋关节置换术取得良好效果的一个要求是对骨缺损进行分类，并且在原植入物区域或在存在骨缺损的情况下，在稳定的骨干骨中位于原区域远端要有机械稳定的固定。有人提出了自体骨或异体骨移植堆积以及完全清除骨水泥和碎屑的可能性。无骨水泥翻修髋关节置换术的优点包括骨量再生以及翻修髋关节系统通常具备的模块化，这允许适应不同的骨结构，并且在再次翻修的情况下，例如在烧结或旋转不良的情况下，还允许部分更换假体。有骨水泥翻修关节成形术仅应在特殊情况下进行，例如边缘性骨缺损或预期寿命较短的老年患者。
