AI Article Synopsis
- Multiple risk factors contribute to anterior cruciate ligament (ACL) reconstruction graft failure, including poor tunnel placement, unaddressed meniscus or ligament injuries, and misalignment in the knee joint.
- Biomechanical studies indicate that conditions like valgus malalignment and increased posterior tibial slope can increase stress on the ACL graft.
- The described surgical technique involves two procedures: an opening-wedge distal femoral osteotomy to correct valgus alignment and a closing-wedge proximal tibial osteotomy to address the tibial slope, followed by revision ACL reconstruction, allowing for earlier weight bearing post-surgery.
Article Abstract
Multiple risk factors for anterior cruciate ligament (ACL) reconstruction graft failure have been reported, including improper tunnel placement, unrepaired meniscus or ligamentous injuries, and coronal/sagittal malalignment. Various biomechanical studies have reported on the increased forces experienced by the ACL graft when there is valgus malalignment or increased posterior tibial slope. This technique describes an opening-wedge distal femoral osteotomy to correct valgus alignment and a closing-wedge proximal tibial osteotomy to correct increased posterior tibial slope in the setting of an ACL reconstruction graft failure. This technique is the first stage of a 2-stage surgery in which the second stage is the revision ACL reconstruction. By performing both osteotomies first, the patient can begin weight bearing earlier after the revision ACL reconstruction.
