摘要：
A force and rotation sensing device can be suitable for measuring a force within a knee joint. A force sensor can measure a force exerted between opposing surfaces of a housing. A force display positioned on the housing can visually represent a value of the measured force, such as with a dual-sided light-emitting diode display that is visible from opposing sides of the housing. A first rotation sensor can measure a flexion/extension position of the housing. A flexion/extension display can visually represent a value of the measured flexion/extension position. In some examples, a zero button can set a reference orientation of the housing, so that the first rotation sensor can measure the flexion/extension position as a relative rotation with respect to the reference orientation. In some examples, circuitry can wirelessly transmit data corresponding to the value of the measured flexion/extension position.
