Prosthetic system to replace the anterior crossed ligament of the knee and semi-removable modular prosthesis of the anterior crossed ligament of the knee

摘要

The present invention relates to a prosthetic system to replace the anterior crossed ligament of the knee in two surgical phases, the first phase consisting of placing two non-removable osteointegrable fixation bases and the superstructures of the first phase and the second phase consisting, when the non-removable fixation bases have been osteointegrated with the bone tissue of their insertion site, of fitting a functional neoligament system replacing the anterior cross ligament of the knee, and the superstructure of the second phase; the fixation bases consist of a tibial implant (TI) on the tibia and a femoral implant (IF) on the femur, the superstructures of the first surgical phase comprising on the tibial side an implant support (PI), an external phantom (FE) and an internal phantom (FI), and comprising on the femoral side a femoral phantom (FF), the superstructures of the second surgical phase comprising, on the tibial side, the removable ligament complex (CLA) and comprising on the femoral side a locking system (SB) and the covering cap (CC).IMAGE
