Navigation In Total Knee Replacement

Knee arthroplasty has been indicated with growing frequency, especially over the last decade. Its success depends on various factors, such as component design, the quality of the material used to make the component, the manufacturing process, adequate patient selection and the surgical technique.

Most of these are developed by the surgical material and implant industry, and the evolution of the industry has enabled great advances in the quality of the prostheses available. On the other hand, with regard to surgical technique, surgeons are the primary factor and evolution of concepts and surgical strategy are the main factors for advances. Within this field, the most significant advance over the past decade has been the emergence of navigation systems for knee arthroplasty.

Computer Assisted Orthopedic Surgery (CAOS) is a field of technological evolution that has been developing particularly over the last 10 years. These include workstations for preoperative planning and simulation and robotics for use in carrying out surgical procedures, and among these, navigation systems.

The basic precepts of knee arthroplasty include reestablishment of the alignment of the lower limb and maintenance or recovery of joint stability. Navigation systems provide guidance and they measure various intra operative parameters that help surgeons to reach these objectives.
