1. A ligament laxity measuring system configured for measuring ligament laxity between a first limb and a second limb connected to each other, comprising:
a force module comprising a force sensor, wherein the force module is configured for being disposed on the first limb and for providing an external force to make the first limb pivot or twist with respect to the second limb, thereby generating a pivoting (varus/valgus) value and a twisting (rotational) value, and the force module generates a force signal based on the external force; an angle sensing module, wherein opposite two segments of the angle sensing module are disposed on the first limb and the second limb respectively, the angle sensing module is configured for sensing the pivoting (varus/valgus) value and the twisting (rotational) value of the first limb and generating an angle signal; and a data processing module connected to the force sensor of the force module and the angle sensing module, wherein the data processing module is configured for calculating a functional relationship of force and angle based on the force signal and the angle signal, and the ligament laxity is measured based on the functional relationship of force and angle. |
