Total hip arthroplasty (THA) is a very satisfactory surgical procedure for end-stage hip disorders.Implant modifications, such as large femoral heads to improve stability, porous metals to enhance fixation and alternative bearings to improve wear, have been introduced over the last decade in order to decrease the rate of early and late failures.There is a changing pattern of THA failure modes.The relationship between failure modes and patient-related factors, and the time and type of revision are important for understanding and preventing short and late failure of implants.The early adoption of innovations in either technique or implant design may lead to an increased risk of early failure.

全髋关节置换术（THA）是治疗终末期髋关节疾病非常令人满意的外科手术。在过去十年中，为了降低早期和晚期失败率，人们引入了一些植入物改良措施，比如采用大尺寸股骨头以提高稳定性、多孔金属以增强固定效果以及使用替代轴承以改善磨损情况。全髋关节置换术的失败模式正在发生变化。失败模式与患者相关因素之间的关系，以及翻修的时间和类型，对于理解和预防植入物的早期和晚期失败都很重要。在技术或植入物设计方面过早采用创新可能会增加早期失败的风险。引用本文：2018；3 DOI：10.1302/2058-5241.3.170068。
