The main objective of this study is to describe a surgical technique that combines intra-and extra-articular techniques using the semitendinosus, gracilis, and peroneus longus to perform reconstruction of the anterior cruciate ligament and anterolateral ligament. This technique offers a more stable, fast, low-cost, and widely accessible procedure and consists of drilling 3 tunnelsd1 femoral and 2 tibial tunnelsdin which the grafts are fixed with interference screws. The fact that the peroneus longus graft is long and thick allows for robust reconstruction of the aforementioned ligaments.

Purpose To describe the femoral insertion of the ACL using the posterior proximal cartilage of the lateral femoral condyle as the anatomical reference. Methods Twenty knees were dissected. The X-axis (deep-shallow) and Y-axis (high-low) were determined using the femoral diaphysis and the proximal cartilage of the lateral femoral condyle (point C) as a reference, which were easily identiied by direct visualization through the anteromedial portal. The distances to the center of the anteromedial and posterolateral bands and to the center of the ACL were measured. ResultsThe mean distances were 7.2 mm (SD: 0.7) between the center of the anteromedial bundle and the Y-axis (AM-Y), 9 mm (SD: 1.1) between the center of the ACL and the Y-axis (M-Y), and 12.7 mm (SD: 0.9) between the center of the posterolateral bundle and the Y-axis (PL-Y). Regarding the distance (from point C to the distal cartilage along the X-axis), the center of the anteromedial bundle (AM) was 35% (SD: 4.9%), the center of the posterolateral bundle was 62% (SD: 3.7%), and the center of the ACL (M) was 44% (SD: 7%) of the CD distance on average. Conclusion Given the similarity among the specimens in terms of the height of the ACL on the Y-axis in relation to the proximal posterior cartilage of the femoral lateral condyle (point C), this point can be used as an arthroscopic intraoperative parameter to deine the position of the femoral tunnel in ACL reconstruction for single-or double-bundle techniques.
