How does Ligamys work?
The Ligamys implant consists of three components:
The sturdy thread briefly takes over the functions of the injured cruciate ligament, and for this reason, it is guided through the femur and tibia. To secure it, thin channels running in the direction of the torn cruciate ligament are drilled into both bones, and the thread is pulled through these channels.
The metal plate (flip anchor) secures the polyethylene thread to the outside of the femur. It is not fixated there but instead is held there through the thread tension alone.
Metal sleeve with spring system:
The so-called monobloc is introduced diagonally from below into the tibial head, and the other end of the polyethylene thread is secured in it.
The spring system enables stability and protection against overloading during knee movements: It absorbs the tensile forces that act on the thread during movements, and as a result, the thread remains taut at all times and sufficiently stabilises the knee. At the same time, the spring absorbs force peaks that could have a negative effect on the potential regeneration of the cruciate ligament.
