Abstract
A probe used during a total knee arthroplasty for measuring forces and locations of their points of application and thereby moments includes two load sensitive plates t to be inserted in one joint-compartment of a knee joint each and each being provided with a top surface and a bottom surface. At least two load sensors may be situated on the top surfaces and/or the bottom surface of each load sensitive plate.

17. A probe used during a total knee arthroplasty for measuring force amplitudes and force locations, comprising:
first and second load sensitive plates connected to each other, 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 includes at least three load sensors that are non-colinearly arranged in such a way as to allow measurement of the force amplitudes and force locations along two perpendicular axes. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A probe used during a total knee arthroplasty for measuring force amplitudes and force locations, comprising:
first and second load sensitive plates separated from one another at a gap between adjoining side walls thereof, the first and second plates being adapted for insertion into a joint-compartment of a knee joint, wherein each of the first and second load sensitive plates includes at least two load sensors, the first and second plates being electrically connected to one another across the gap between the adjoining side walls. - View Dependent Claims (31, 32, 33, 34, 35, 36)
