A tensor sensor can be used to measure deformations in an object that are not visible to the naked eye by detecting the stress change inside the object. Such sensors have a wide range of application. For example, a tensor sensor can be used to predict fatigue in building materials by detecting the stress change inside the materials, thereby preventing accidents.

Objective: To investigate a modified robotized hydraulic tensor for management of the ligament balance in the total knee arthroplasty.
Methods: The effect of the modified robotized hydraulic tensor on the mechanical behaviour of the ligament system balance in the total knee arthroplasty was analyzed and the related information was obtained.
Results: The robotized hydraulic tensor acted as a tensor-sensor system, which could assist the surgeon by providing the quantitative information to align the lower limb in extension, equalize the articular spaces in extension and flexion, balance the internal and external forces, and define the femoral component rotation, and by providing the information to plan the releasing of the soft tissues and the rotating of the femoral component.
