Accumulated knowledge about hip replacement arthroplasty has identified a number of mechanical factors that contribute to implant failure. The mechanics of component design, materials selection, implant fixation, and response of bone and soft tissue structures to an altered loading environment are variables that influence outcome. Revision arthroplasty presents additional problems of loss of bone stock, cortical perforation or fracture, and implant removal that must be appreciated to prevent recurrent failure.
关于髋关节置换术的累积知识已经确定了一些导致植入物失败的机械因素。部件设计、材料选择、植入物固定以及骨和软组织结构对改变的负荷环境的反应等力学因素是影响手术结果的变量。翻修关节成形术带来了额外的问题，如骨量丢失、皮质穿孔或骨折以及植入物取出，必须认识到这些问题以防止再次失败。
