Applying Allogeneic Cortical Bone Press-Fit Screw in Fixation of Anterior Cruciate Ligament Reconstruction
- 15 Downloads
There are many fixation methods in anterior cruciate ligament reconstruction by using multiple hamstring tendons. The extra cortical fixation such as Endobutton is widely used (Fig. 23.1). The extra cortical fixation has the largest strength, no cutting of the graft, and full contact between graft and tunnel; however, the fixation point is far from the anatomic insertion of the ACL on the femur which could lead to the bungee and the windshield-wiper effect (Fig. 23.2), [1–6]. How to avoid the disadvantages above is a critical problem.
