1. A prosthetic component configured to measure load and position of load applied by the muscular-skeletal system comprising:

  • a first support structure;

    electronic circuitry wherein the electronic circuitry is configured to control a measurement process and to transmit measurement data;

    a plurality of load sensors;

    an interconnect coupling the plurality of sensors to the electronic circuitry;

    a second support structure coupled to the first support structure to form a hermetically sealed housing to isolate the electronic circuitry and the plurality of load sensors from an external environment wherein the plurality of sensors are integrated with the interconnect, and wherein the plurality of load sensors are configured to measure a load magnitude and position of load applied to the prosthetic component; and

    a rigid load plate having a first surface and a second surface wherein the first surface of the rigid load plate is coupled to an interior surface of the second support structure, wherein the second surface of the rigid load plate couples to the plurality of load sensors, and wherein a portion of the interconnect is between the second surface of the rigid load plate and a first surface of the first support structure.
