Surgical technique

The Ligamys implantation is performed arthroscopically and generally takes about 45 minutes: First, the monobloc is introduced into the tibial head using a targeting device. Then the channel for the polyethylene thread is drilled in the femur. The thread is secured with a flip anchor and guided through the femur to the tibial head and to the monobloc.

Before the polyethylene thread is secured in the monobloc, microfracturing is performed: Using an awl, a few small holes are punched into the femur through which stem cells can migrate into the joint to promote regeneration.

Then the thread is secured in the spring system in the monobloc under predefined tension. This is intended to prevent the femur and tibia from being able to shift relative to one another during movements of the knee. The ruptured ligament is relieved and is provided with the rest needed so that it can possibly grow back together.

The two cruciate ligament stumps are not sutured together, but are approximated using an absorbable suture. The torn ends lie loosely on each other and can ideally grow back together without any tensile strain.
