19. A contact sensor, comprising:

  • a data acquisition terminal; and

    a surgical insert defining a contact surface configured to receive a load applied by an electrically conductive joint element, the contact surface having selected spaced conductive portions, wherein the selected spaced conductive portions define an array of sensing points, wherein the array of sensing points is in communication with the data acquisition terminal, and wherein the surgical insert is configured for insertion therein a selected joint within the body of a subject,wherein, during application of the load, at least one sensing point of the array of sensing points is configured to produce an output signal indicative of the change in electrical resistance experienced across the contact surface at the sensing point, and wherein the output signal produced by each sensing point corresponds to variations in the load between the electrically conductive joint element and the contact surface.
