The goal of this paper is to review the biomechanical and clinical rationale for single-bundle versus double-bundle posterior cruciate ligament (PCL) reconstruction. The primary question is whether there has been demonstrated any clear biomechanical or clinical superiority of a double-bundle reconstruction over a single-bundle reconstruction.
There is some recent evidence demonstrating biomechanical superiority of double-bundle versus single-bundle reconstruction; however, this is not definitive. Clinical superiority has not been clearly demonstrated as of yet. The primary question which served as the basis of this review remains unanswered. There is recent biomechanical data to suggest a potential benefit of double-bundle versus single-bundle reconstruction, but not all studies are in agreement. Furthermore, the possible biomechanical advantages have not yet been borne out in clinical studies. At this point, we cannot clearly recommend one technique versus another and the decision should be left to the treating surgeon.
本文旨在回顾单束与双束后交叉韧带（PCL）重建的生物力学及临床依据。主要问题在于，双束重建相对于单束重建是否已展现出明确的生物力学或临床优势。
近期有一些证据表明双束重建在生物力学方面优于单束重建；然而，这并不确凿。截至目前，临床优势尚未得到明确证实。作为本综述基础的主要问题仍未得到解答。近期生物力学数据提示双束重建相对于单束重建可能存在潜在益处，但并非所有研究都达成一致。此外，临床研究尚未证实可能的生物力学优势。此时，我们无法明确推荐一种技术优于另一种技术，决策应留给主刀医生。
