How does Ligamys work?

Ligamys consists of three components: A polyethylene thread having a metal plate (flip anchor) on one end and a metal sleeve (monobloc) with an integrated spring system in which the thread is dynamically attached between the femur and tibia.

The polyethylene thread
takes over the joint-stabilising function of the anterior cruciate ligament. It additionally creates the mechanical connection between the femur and tibia in which it is guided through the corresponding drill channels. Its course follows that of the ruptured ACL.

The flip anchor
secures the polyethylene thread to the outside of the femur

The monobloc
with the integrated spring system receives the polyethylene thread at the medial side of the tibia and is dynamically anchored there under predefined tension. In doing so, the monobloc is introduced into the tibia diagonally, from below. The integrated spring system can thus hold the secured thread under sufficiently taut tension during all phases of movement of the knee.

The anchoring point of the polyethylene thread in the monobloc is dynamic and shifts with knee movement. As a result, Ligamys avoids the disadvantages of a rigid point-to-point connection. The spring mechanism can thus promote the biological healing of the ligament.

The materials used in Ligamys have been proven in medical practice for many years.

The flip anchor is made of titanium (Ti), the thread of polyethylene (UHMWPE), the monobloc of stainless steel (FeCrNiMnMoNbN) and the spring contained therein of Phynox® (CoCr steel).
