The design of and early clinical results with the uncemented porous-coated LSF Anatomic and Midstem Total Hip Systems are described. In a Food and Drug Administration-approved program, a random selection method was used to determine which patients receive implants with a hydroxyapatite (HA) coating applied to the porous surface and which patients receive non-HA-coated implants. The early clinical results with the HA-coated systems appear superior to the non-HA-coated systems. A greater percentage of patients with HA systems have clinical scores in the excellent/good range, which is primarily a reflection of less prosthesis-related pain. Radiographically, all components appear well fixed with evidence of bone ingrowth. The HA-coated systems have a decreased incidence of radiolucencies, particularly in proximal zones.
描述了非骨水泥型多孔涂层LSF解剖型和中柄全髋关节系统的设计及早期临床结果。在一项获得美国食品药品监督管理局批准的项目中，采用随机选择方法来确定哪些患者接受在多孔表面涂有羟基磷灰石（HA）涂层的植入物，哪些患者接受未涂HA涂层的植入物。HA涂层系统的早期临床结果似乎优于未涂HA涂层的系统。接受HA系统的患者中，有更高比例的患者临床评分处于优秀/良好范围，这主要反映出与假体相关的疼痛较少。在影像学上，所有组件看起来固定良好，有骨长入的证据。HA涂层系统的透光线发生率降低，尤其是在近端区域。
