Total hip arthroplasty has yielded excellent results in decreasing pain and enhancing function in patients with hip degenerative disease. However, the problems associated with prosthetic failure and the consequent need for revision surgery still represent a major clinical issue. The most common reasons for revision surgery include implant loosening, periprosthetic osteolysis, infection, malalignment, stiffness, implant failure or fracture, and wear. The need for eliminating or reducing wear plays a crucial role in refining prosthesis composition and design. In this regard, it is important to develop new techniques for more accurate and reproducible measurement of wear. This should allow earlier detection of increased wear and thus permit earlier identification of patients who are at risk, and also help to identify faulty implant designs. This work is aimed at discussing the most common in vivo and in vitro methods used for evaluating the wear of hip prosthesis components.
全髋关节置换术在减轻髋关节退行性疾病患者的疼痛和增强其功能方面已取得了优异的效果。然而，与假体失败相关的问题以及随之而来的翻修手术需求仍然是一个重大的临床问题。翻修手术最常见的原因包括植入物松动、假体周围骨溶解、感染、排列不齐、僵硬、植入物失败或骨折以及磨损。消除或减少磨损的需求在改进假体成分和设计方面起着至关重要的作用。在这方面，开发更准确、可重复的磨损测量新技术非常重要。这将有助于更早地检测到磨损增加，从而更早地识别出有风险的患者，也有助于识别有缺陷的植入物设计。 这项工作旨在讨论用于评估髋关节假体部件磨损的最常见的体内和体外方法。
