OBJECTIVE
To review the application of three-dimensional (3D) printing patient-specific cutting guides (PSCG) in open-wedge high tibial osteotomy (OWHTO).
METHODS
The domestic and foreign literature about the use of 3D printing PSCG to assist the OWHTO in recent years was reviewed, and the effectiveness of different types of 3D printing PSCG to assist OWHTO was summarized.
RESULTS
Many scholars design and use different 3D printing PSCGs to confirm the precise positioning of the osteotomy site (the bone surface around the cutting line, the "H" point of the proximal tibia, the internal and external malleolus fixators, .) and the correction angle (the pre-drilled holes, the wedge-shaped filling blocks, the angle-guided connecting rod, .) during operation, and all of them achieve good effectiveness.
CONCLUSION
Compared with conventional OWHTO, 3D printing PSCG assisted OWHTO has many obvious advantages, such as shortening the operation time, and the frequency of fluoroscopy, and being closer to the expected preoperative correction, . However, the effectiveness between different 3D printing PSCGs still need to be discussed in the follow-up studies.
目的
回顾三维（3D）打印个性化截骨导板（PSCG）在开放性楔形高位胫骨截骨术（OWHTO）中的应用。
方法
回顾近年来国内外关于使用3D打印PSCG辅助OWHTO的文献，并总结不同类型3D打印PSCG辅助OWHTO的有效性。
结果
许多学者设计并使用不同的3D打印PSCG来确定手术过程中截骨部位（切割线周围的骨面、胫骨近端的“H”点、内外踝固定器等）和矫正角度（预钻孔、楔形填充块、角度引导连杆等）的精确定位，且均取得了良好的效果。
结论
与传统的OWHTO相比，3D打印PSCG辅助OWHTO具有许多明显优势，如缩短手术时间、减少透视次数、更接近术前预期矫正效果等。然而，不同3D打印PSCG之间的有效性仍需在后续研究中进行探讨。
