Despite multiple advances in techniques for posterior cruciate ligament reconstruction (PCL-R), residual posterior laxity continues to be a commonly reported complication. Multiple studies demonstrated a decreased or flat posterior tibial slope, increases posterior laxity, and forces placed across the native and reconstructed PCL. Anterior opening wedge high tibial osteotomies (aOW-HTO) can be used to increase posterior tibial slope, thereby reducing tibial sag and posterior laxity. Depending on the technique used, anterior opening wedge osteotomies can lead to changes in patellar height, affecting patient pain and satisfaction. The purpose of this article is to describe a technique for an aOW-HTO with a tibial tubercle osteotomy and concomitant PCL-R to increase the posterior tibial slope while minimizing changes to patellar height.
尽管后交叉韧带重建（PCL-R）技术取得了多项进展，但残留的后向松弛仍然是常见的并发症。多项研究表明，胫骨后倾坡度减小或变平会增加后向松弛以及作用于天然和重建后交叉韧带的力。前开口楔形高位胫骨截骨术（aOW-HTO）可用于增加胫骨后倾坡度，从而减少胫骨沉降和后向松弛。根据所使用的技术，前开口楔形截骨术可能会导致髌骨高度改变，影响患者的疼痛和满意度。本文的目的是描述一种采用胫骨结节截骨术和同期PCL-R的aOW-HTO技术，以增加胫骨后倾坡度，同时尽量减少对髌骨高度的改变。
