The concept of unicondylar knee arthroplasty (UKA) has been described as early as 1950s following the introduction of the MacIntosh and McKeever hemiarthroplasty. With improvements in implant design, patient selection, and surgical technique, there has been an increase in utilization of UKA as a less-invasive alternative to total joint arthroplasty for the treatment of localized symptomatic osteoarthritis. The purpose of this review article is to highlight five trending concepts in UKA based on current evidence: bearing design, fixation technique, medial vs. lateral UKA, implant survivorship, and revision surgery.
单髁膝关节置换术（UKA）的概念早在20世纪50年代就已被提出，当时MacIntosh和McKeever半关节置换术问世。随着植入物设计、患者选择和手术技术的改进，UKA作为全关节置换术的一种侵入性较小的替代方法，在治疗局限性症状性骨关节炎方面的应用有所增加。这篇综述文章的目的是根据现有证据强调UKA的五个流行概念：轴承设计、固定技术、内侧与外侧UKA、植入物生存率和翻修手术。
