Unicompartmental knee arthroplasty(UKA) is an important surgical technique for the treatment of end-stage knee osteoarthritis, which has high requirement for the position and angle of the prosthesis. The application of three-dimensional(3D) printed in UKA reflects several characteristics such as accuracy,efficiency and safety,but the current research results show that there is still lack of consistency in the design of 3D printed guides and the standard of prosthetic position parameters. This article reviews the history, manufacturing requirements and process of 3D printed guides during UKA surgery, as well as the results of current clinical research. Whether 3D printed guides can safely and effectively improve the placement accuracy of inexperienced doctors during UKA surgery,and whether the long-term results are worthy of clinical promotion need further verification.单髁置换术（UKA）是治疗终末期膝关节骨关节炎的一种重要的外科手段，其对假体位置和角度的精准度要求较高。三维打印导板应用于UKA可以提高手术精准性，术中操作便捷，安全性高。但目前导板的设计、假体位置参数等尚缺乏统一标准。本文梳理了UKA术中三维打印导板的历史、制作要求和过程，以及目前的临床研究结果。三维打印导板是否可以安全、有效地提高无经验医师在UKA术中的假体安放精准度，以及长期结果是否值得在临床上进行推广仍有待进一步的验证。.
