Abstract

The article introduces a novel tibia fixation device, the Cobra Ligament Fixation Device (Cobra LFD), for anterior cruciate ligament reconstruction. The Cobra LFD has a low profile and is hooked upon the cortical bone of tibia. It is useful either for primary ACL reconstruction or for ACL revision surgery, mainly for fixation of hamstring grafts. Fixation in the cortical bone is of great importance, in particular for revision cases. Besides technical aspects, we also present the 4-year follow-up of 15 cases of ACL revision surgery, where the Cobra LFD has been used for the tibia fixation.
