| 1. A probe used during a total knee arthroplasty for measuring force amplitudes and force locations comprising:
a first and second load sensitive plate, each for insertion into a joint-compartment of a knee joint and each having a top
surface and a bottom surface,
wherein each of the first and second load sensitive plates each include at least two load sensors, and
wherein the first and second load sensitive plates have adjoining inner lateral side walls and are connected at the adjoining
inner lateral side walls.
