Notwithstanding the contributions of soft tissue restraints on postoperative kinematics and long-term survival after total knee arthroplasty (TKA), there is an emerging consensus that the underlying anatomy, especially the posterior inclination of the tibial plateau in the sagittal plane (tibial slope), might just have a comparable impact. However, this has not been fully elucidated as yet. Therefore, a thorough literature search, analysis and presentation of current scientific data was conducted. The tibial slope has been shown to relate linearly to the postoperative range of motion and function of the extensor mechanism. Furthermore, it impacts wear of the tibial insert and loosening, as well as instability of the TKA. As no consensus has been reached on the ideal tibial slope, recommendations range from 0° to 10°. Notably, more recent studies favor reconstructing the native, preoperative tibial slope, and the majority of authors advocate that knowledge of this is crucial for optimal TKA surgery.
尽管软组织限制对全膝关节置换术（TKA）后的术后运动学和长期生存率有贡献，但一种新出现的共识是，潜在的解剖结构，尤其是矢状面胫骨平台的后倾（胫骨坡度），可能具有类似的影响。然而，这一点尚未得到充分阐明。因此，我们对当前的科学数据进行了全面的文献检索、分析和呈现。胫骨坡度已被证明与术后活动范围和伸肌机制功能呈线性相关。此外，它还会影响胫骨假体的磨损和松动，以及TKA的不稳定性。由于尚未就理想的胫骨坡度达成共识，建议范围从0°到10°。值得注意的是，最近的研究倾向于重建术前的自然胫骨坡度，并且大多数作者主张了解这一点对于最佳的TKA手术至关重要。
