System and method for assessing, measuring, and correcting an anterior-posterior bone cut

A method of measuring anterior-posterior slope or tilt in support of a bone cut comprising the steps of:

• placing a first bone and a second bone in approximately extension;
• coupling a sensored insert to a bone landmark of the first bone;
• referencing a three-axis accelerometer of a sensored insert to the bone landmark when the bone is in approximately extension and where the three-axis accelerometer measures position, tilt, and rotation;
• coupling a first bone cutting jig to the first bone;
• coupling a second bone cutting jig to the second bone;
• transmitting data from the three-axis accelerometer of the sensored insert related to the anterior-posterior slope of a bone cut of either the first bone cutting jig or the second bone cutting jig;
• displaying the position of the first and second on the remote system;
• and
• displaying the anterior-posterior slope of the bone cut of either the first or second bone cutting jigs.

A method of measuring anterior-posterior slope or tilt in support of a bone cut comprising the steps of:

• placing a femur and a tibia in approximately extension;
• coupling a sensored insert to a tibial crest of the tibia;
• referencing a three-axis accelerometer of a sensored insert to the tibial crest when the bone is in approximately extension and where the three-axis accelerometer measures position, tilt, and rotation;
• coupling a first bone cutting jig to a tibia;
• coupling the sensored insert to the first bone cutting jig;
• and
• measuring the anterior-posterior slope of a tibial bone cut of the first bone with the three-axis accelerometer.
