Single- or Double-Bundle Technique in the Anterior Cruciate Ligament Reconstruction — Current Concepts and Review of the Literature

The treatment for anterior cruciate ligament (ACL) deficient knee consists in its surgical reconstruction. There are several available and validated techniques, but there are still numerous questions to be answered concerning the best approach in terms of stability, functional outcome, and avoiding further damage in the knee. This paper sought to analyze the studies published in the literature comparing the outcomes of ACL restoration with single-bundle versus double-bundle techniques. The results demonstrate that even if biomechanical studies find an increased steadiness with double-bundle ACL reconstruction, there seems to be no clinical or functional benefit compared with single-bundle reconstruction.
