Anatomic Single-Bundle ACL Reconstruction with Remnant Augmentation Technique

Anterior cruciate ligament (ACL) injury is the common ligamentous injury of the knees. An ACL reconstruction is the procedure that has been proven to improve knee stability and functional outcomes and may prevent the osteoarthritic changes and subsequent meniscal injuries. The ACL reconstruction techniques have been developed in various ways. Anatomical single-bundle ACL reconstruction with remnant augmentation tech- nique is the optimal reconstruction procedure. It may improve the clinical outcomes of biological healing, preserve the proprioceptive function, and has shown less tibial tunnel widening postoperatively. This chapter presents the step-by-step technique of an anatomical single-bundle ACL reconstruction, indication and contraindication for surgery, the preferred graft choice, fixation methods, pearls and pitfalls of the procedure, and postoperative rehabilitation. The review of literatures about the remnant preserving ACL reconstruction is also discussed in this chapter.
