Reconstruction of Anterior Cruciate Ligament (ACL)


Important conditions for a good result for the reconstruction of the anterior cruciate ligament are the introduction of arthroscopic surgical techniques and the early specific functional aftercare with immediate full extension. The ligament appliance of the knee provides stability for the movement of femur and tibia. The anterior cruciate ligament (ACL) secures the tibial shift onward, whereas the posterior cruciate ligament (PCL) secures the tibial shift to the rear. 

The lateral ligaments are responsible for the lateral rotation of the knee joint. The meniscus intercepts the strong exposure of the femur and tibia like an airbag.

With the OrthoPilot® navigation system it is possible to apply the drilling channels of the anterior cruciate ligament reconstruction. The knee kinematics of the leg is the basis for the isometry and impingement calculations (function impairment of the joint mobility), which are calculated by the computer with the help of intraoperatively registered transaction data of the leg. Relevant anatomical structures are considered by the operating surgeon by scanning with a pointer. Optionally planning data from x-rays can be integrated as a further basis for navigation. The aiming device can be precisely positioned and controlled with the help of the computer. Thus the adapted holes for the tendon transplants can be exactly applied. Compared to many other systems the OrthoPilot® navigation system is abandoned from additional image-guided preliminary analysis of the patient. Therefore there are no exposure doses by CT-scans. The substantial advantage with the insertion of the OrthoPilot® is the accuracy during the adjustment of the drill channel – the condition for a long durability of the anterior cruciate ligament reconstruction and a good joint function.
