The implementation of cementless joint replacement prostheses is proving to be a significant advance in orthopedic surgery. The porous-coated implant, stabilized by the biologic fixation resulting from bone ingrowth, is one of several types of cementless devices. A historical review of porous materials reveals that the concepts underlying biologic fixation date back decades. It was the initial concerns about the long-term performance of bone cement that, in the early 1970s, stimulated several groups more actively to pursue the development of porous systems. As a result of their efforts, there are currently many different porous coatings and prosthetic designs undergoing clinical investigation, with generally encouraging results. However, it is becoming clear that the importance of porous-coated prosthetic devices is not that they will serve to replace cemented prostheses entirely, but rather that they offer viable alternatives for the treatment of certain populations of patients. An understanding of the evolution of porous-coated implants can help to identify gaps in our knowledge and areas that require additional study, to direct future design modifications of implants, and to foster effective implementation of the prostheses.
无骨水泥关节置换假体的应用正被证明是骨科手术中的一项重大进展。多孔涂层植入物通过骨长入产生的生物固定作用实现稳定，是多种无骨水泥装置之一。对多孔材料的历史回顾表明，生物固定背后的概念可以追溯到几十年前。正是对骨水泥长期性能的最初担忧，在20世纪70年代初促使多个研究团队更积极地致力于多孔系统的开发。由于他们的努力，目前有许多不同的多孔涂层和假体设计正在进行临床研究，总体结果令人鼓舞。然而，越来越明显的是，多孔涂层假体装置的重要性并不在于它们将完全取代有骨水泥的假体，而是在于它们为某些患者群体的治疗提供了可行的替代方案。了解多孔涂层植入物的发展历程有助于识别我们知识中的空白以及需要进一步研究的领域，指导未来植入物的设计改进，并促进假体的有效应用。
