LOCALITE KneeNavigator





The LOCALITE KneeNavigator is a CT-less navigation system for knee replacement (total and unicondylar prosthesis).

Determination of the Mechanical Axis
The essential prerequisite for an optimal implantation in total knee arthroplasty is to align femur and tibia along the mechanical axis of the leg. Without a navigation system, this axis is determined from preoperative data and is then transferred to the patient by means of a template. Here the precision of the surgery depends largely on the surgeon's experience and the patient's anatomy. In many cases, the alignment along the mechanical axis is less than optimal.

CT-less Navigation Without Preoperative Planning
The LOCALITE KneeNavigator determines the leg's mechanical axis by capturing the patient's kinematical data and anatomical landmarks that provide a precise representation of the patient's anatomy. There is no need for additional x-ray exposure or for time-consuming preoperative planning based on CT images. The LOCALITE KneeNavigator acquires all the data needed for an optimal implantation during the actual operation.

Software Customization to Individual Requirements
With the LOCALITE KneeNavigator the surgical procedure is identical to conventional surgery, except for a few additional steps that are an absolute must for navigation. The LOCALITE KneeNavigator can easily be adapted to any type of prosthesis and also to the surgeon's individual preferences. It does not force the surgeon to learn a specific technique, but lets him compare each computer-supported step to his normal routine. The surgeon may even continue to work with the methods for orientation that he is accustomed to, and can use the navigation system as an additional support. Thus, the LOCALITE KneeNavigator assists the surgeon without detaching him from the actual operation.

Navigation for Minimally Invasive  Unicondylar Implantation
The LOCALITE KneeNavigator can be extended to support navigation of unicondylar prosthetics. A special set of instruments and additional software provide navigation support for minimally invasive surgery. Even here, no preoperative CT is needed; all relevant data are acquired during the operation.

Open Platform for All Makes of Prostheses
The LOCALITE KneeNavigator is independent of endoprosthesis manufacturers. It provides an open platform that lets the surgeon choose from  different makes of prostheses and still work with one and the same navigation system. Hospitals that implant different brands of prostheses need to invest in only one navigation system: LOCALITE KneeNavigator.
