Course of the operation
Ligamys is used arthroscopically and in a minimally invasive manner (as gentle as possible). The surgery can be performed in either general or regional anaesthesia and usually lasts about 45 minutes.
For the procedure, special instruments are inserted into the knee joint through small incisions. Using a camera, the situation within the joint is shown on a monitor. At the start of the procedure, the surgeon obtains an overview within the knee and verifies the diagnosis. Ligamys is used only if the anterior cruciate ligament is torn in such a manner that there is a chance of regeneration, and if it is indicated.
In general, the metal sleeve with spring system is anchored in the tibial head in a first step. Then drilling is performed in the femur for the polyethylene thread. The thread is now pulled through the femur and the drilling channel in the tibial head to the monobloc and the spring system.
A procedure known as microfracturing is performed as the next step: Using an awl, small holes are created in the femur so that stem cells are released and can migrate into the joint. This method can support the healing of joint injuries. Finally, the polyethylene thread is secured in the spring system under the specified tension. The thread can stabilise the injured knee and provide the ruptured cruciate ligament with the rest needed to enable it to grow back together.
The two cruciate ligament stumps are not sutured. A fine auxiliary suture, which later dissolves, is intended to align the two ends so that they lie loosely on each other and can grow back together without any tensile strain.
