To summarize the application status of three-dimensional (3-D) printing technique in joint surgery and look forward to the future research directions.
The recent original articles about the application and research of 3-D printing technique in joint surgery were extensively reviewed and analyzed.
In clinical applications, 3-D printing technique can provide "tailored" treatment and custom implants for patients, which helps doctors to perform the complex operations easier and more safely; in fundamental research, tissue engineered scaffolds with desirable external shape and internal organization are easily fabricated with 3-D printing technique, which can meet the demand of cell adherence and proliferation. Even more, cells may be deposited with the biomaterials during the printing.
With the development of medical imaging, digital medicine and new materials, 3-D printing technique will have a wider range of applications in joint surgery.
总结三维（3-D）打印技术在关节外科的应用现状，并展望未来的研究方向。
广泛回顾和分析近期关于3-D打印技术在关节外科应用及研究的原始文章。
在临床应用中，3-D打印技术可为患者提供“量身定制”的治疗和定制植入物，有助于医生更轻松、安全地进行复杂手术；在基础研究中，利用3-D打印技术可轻松制造出具有理想外形和内部结构的组织工程支架，能满足细胞黏附和增殖的需求。甚至在打印过程中，细胞可与生物材料一起沉积。
随着医学成像、数字医学和新材料的发展，3-D打印技术在关节外科将有更广泛的应用。
