Anterior cruciate ligament reconstruction failure remains a commonly seen outcome despite advances in technique and graft options. Recent studies have shown that the declination of the tibial plateau slope in the sagittal plane affects the in situ stress on the anterior cruciate ligament. The native posterior tibial slope has been described to range from 7° to 10°. However, several authors have suggested that a posterior tibial slope >12° should be considered pathologic. Given the recent evidence, our institution has begun performing a tibial tubercle-sparing anterior closing wedge proximal tibial osteotomy with cross screw fixation to decrease sagittal plane tibial slope.
尽管在技术和移植物选择方面有所进步，但前交叉韧带重建失败仍是常见的结果。最近的研究表明，矢状面胫骨平台坡度的减小会影响前交叉韧带的原位应力。天然胫骨后倾坡度据描述在7°至10°之间。然而，一些作者认为胫骨后倾坡度>12°应被视为病理性的。鉴于最近的证据，我们机构已开始采用保留胫骨结节的前侧闭合楔形近端胫骨截骨术并使用交叉螺钉固定来减小矢状面胫骨坡度。
