Double-bundle (DB) anterior cruciate ligament (ACL) reconstruction has biomechanical advantages over single-bundle reconstruction. However, most studies perform the DB reconstruction with 2 femoral tunnels, which fails to provide an entire femoral footprint for ACL reconstruction. In this study, we describe a femoral double-bundle footprint technique for ACL reconstruction, named the tendon groove technique. This technique modifies the DB femoral tunnels through connecting 2 inner orifices of the anteromedial bundle and the posterolateral bundle tunnels, creating a groove to ensure an entire ACL footprint. This modified technique achieves an anatomic and double-bundle ACL reconstruction with a native footprint, which increases the tendon-bone interface area and theoretically promotes tendon-bone healing in ACL reconstruction.
双束（DB）前交叉韧带（ACL）重建在生物力学方面优于单束重建。然而，大多数研究采用两个股骨隧道进行双束重建，这无法为ACL重建提供完整的股骨足迹。在本研究中，我们描述了一种用于ACL重建的股骨双束足迹技术，称为肌腱沟技术。该技术通过连接前内侧束和后外侧束隧道的两个内口来修改双束股骨隧道，形成一个凹槽以确保完整的ACL足迹。这种改良技术实现了具有天然足迹的解剖学双束ACL重建，增加了腱骨界面面积，理论上促进了ACL重建中的腱骨愈合。
