Abstract
Disclosed herein are a system for determining ligament tension and a method for utilizing the same in a knee balancing procedure. The system according may include a first sensor to measure a first load at a first condyle of a femur, a second sensor to measure a second load at a second condyle of the femur, an inertial measurement unit to measure angular change of a tibial mechanical axis of a tibia during a rotation of the tibia in a coronal plane, and a display in communication with the first sensor, the second sensor and the inertial measurement unit for displaying a ligament stress-strain curve. The method may include the steps of rotating a tibia toward a first condyle, measuring first load values and first deflection angles of the tibia, and determining a stress-strain curve of a first ligament from the first load values and first deflection angles.
