Implant encoder

A joint implant comprising:

• a first implant configured to be coupled to a first bone of a joint, the first implant including:
• a plurality of medial markers located on a medial side of the first implant, and a plurality of lateral markers located on a lateral side of the first implant;
• a second implant configured to be coupled to a second bone of the joint and contacting the first implant, the second implant including:
• at least one medial marker reader to identify a position of the medial markers and at least one lateral marker reader to identify a position of the lateral markers, the position of the medial markers and the position of the lateral markers providing a positional data of the first implant with respect to the second implant,
• a medial load sensor to measure medial load data between the first and second implants on a medial side of the joint implant,
• a lateral load sensor to measure lateral load data between the first and second implants on a lateral side of the joint implant, and
• a processor operatively coupled to the medial marker reader, the lateral marker reader, the medial load sensor and the lateral load sensor,
• wherein the processor simultaneously outputs the positional data, the medial load data and the lateral load data to an external source,
• wherein a number of medial markers is different from a number of lateral markers.

A joint implant comprising:

• a first implant configured to be coupled to a first bone of a joint, the first implant including at least one marker, the marker being a magnetic track disposed along a surface of the first implant;
• a second implant configured to be coupled to a second bone of the joint and configured to contact the first implant, the second implant including:
• at least one marker reader to detect a position of the marker to identify a positional data of the first implant with respect to the second implant, the marker reader being a Hall sensor assembly including at least one Hall sensor, and
• at least one inertial measurement unit to measure a motion data of the second implant, and
• a processor operatively coupled to the marker reader and the inertial measurement unit,
• wherein the processor outputs the positional data and the motion data to an external source.
