Abstract

A reconfigurable orthopedic implant trial comprising: (a) a first orthopedic component; (b) a second orthopedic component that includes a second sensor on a second articulating surface thereof, the second orthopedic component configured to removably mount to the first orthopedic component; (c) a third orthopedic component that includes a third sensor on a third articulating; surface thereof, the third orthopedic component configured to removably mount to the first orthopedic component, where the second sensor and the third sensor are configured to generate kinematic data.

Claims (44)

1. A reconfigurable orthopedic implant trial comprising:

a first orthopedic component including a first sensor on an articulating surface thereof;

a second orthopedic component including a second sensor on an articulating surface thereof, the second orthopedic component configured to be removably mounted with the first orthopedic component;

a third orthopedic component including a third sensor on an articulating surface thereof, the third orthopedic component configured to be removably mounted with to the first orthopedic component;

wherein the first sensor, the second sensor and the third sensor are configured to generate kinematic data.

2. The reconfigurable orthopedic implant trial of claim 1 , wherein:

the first orthopedic component comprises at least one of a tibial tray and a tibial tray insert;

the second orthopedic component includes a first tibial post; and

the third orthopedic component includes a second tibial post;

the first tibial post differs from the second tibial post in at least one of size, shape, and material composition.

3. The reconfigurable orthopedic implant trial of claim 2 , wherein the at least one of a tibial tray and a tibial tray insert of the first orthopedic component includes a plurality of orifices at different locations therein, the orifices configured for receiving a tibial post.

4. The reconfigurable orthopedic implant trial of claim 3 wherein at least one of the tibial posts is configured for being locked with respect to the first orthopedic component to inhibit rotation.

5. The reconfigurable orthopedic implant trial of claim 1 , wherein:

the first orthopedic component comprises at least one of a tibial tray and a tibial tray insert;

the second orthopedic component includes a first condyle receiver; and

the third orthopedic component includes a second condyle receiver.

6. The reconfigurable orthopedic implant trial of claim 5 further comprising at least one condyle configured for being received by one of the first and second condyle receivers.

7. The reconfigurable orthopedic implant trial of claim 6 wherein the at least one condyle includes at least one condyle cutout and at least one condyle insert removably mounted in the at least one condyle cutout.

8. The reconfigurable orthopedic implant trial of claim 5 wherein the first condyle receiver has a different shape from the second condyle receiver.

9. The reconfigurable orthopedic implant trial of claim 5 wherein the first condyle receiver differs from the second condyle receiver in at least one of depth, angle and length.

10. The reconfigurable orthopedic implant trial of claim 5 wherein at least one of the first condyle receiver and second condyle receiver are formed from multiple portions that make up the respective condyle receiver.

11. The reconfigurable orthopedic implant trial of claim 1 , further comprising:

a computer communicatively coupled to at least one of the second sensor of the second component and the third sensor of the third component; and

a database including fabrication instructions for creating and integrating at least one of the first and second orthopedic components without the first and second sensors, and the first and third orthopedic components without the first and third sensors.

12. A reconfigurable orthopedic implant trial comprising:

a first orthopedic component comprising at least one of a tibial tray and a tibial tray insert;

a first sensor on an articulating surface of the first orthopedic component;

a plurality of second orthopedic components, the second orthopedic components including a plurality of tibial posts, each tibial post configured to be removably mounted with the first orthopedic component;

a second sensor on an articulating surface of at least one of the plurality of second orthopedic components;

the tibial posts of the plurality differing from each other in at least one of size, shape, and material composition;

the first sensor and the second sensor configured for generating kinematic data.

13. The reconfigurable orthopedic implant trial of claim 12 , wherein the least one of a tibial tray and a tibial tray insert of the first orthopedic component includes a plurality of orifices at different locations therein, the orifices configured for receiving a tibial post.

14. The reconfigurable orthopedic implant trial of claim 12 wherein at least one of the tibial posts is configured for being locked with respect to the first orthopedic component to inhibit rotation.

15. A reconfigurable orthopedic implant trial comprising:

a first orthopedic component comprising at least one of a tibial tray and a tibial tray insert;

a first sensor on an articulating surface of the first orthopedic component;

a plurality of second orthopedic components, the second orthopedic components including a plurality of condyle receivers, each condyle receiver configured to be removably mounted with the first orthopedic component;

a second sensor on an articulating surface of at least one of the plurality of second orthopedic components;

the first sensor and the second sensor configured for generating kinematic data.

16. The reconfigurable orthopedic implant trial of claim 15 further comprising at least one condyle configured for being received by one of the plurality of condyle receivers.

17. The reconfigurable orthopedic implant trial of claim 16 wherein the at least one condyle includes at least one condyle cutout and at least one condyle insert removably mounted in the at least one condyle cutout.

18. The reconfigurable orthopedic implant trial of claim 15 wherein the plurality of condyle receivers differ in shape.

19. The reconfigurable orthopedic implant trial of claim 15 wherein the plurality of condyle receivers differ in at least one of depth, angle and length.

20. The reconfigurable orthopedic implant trial of claim 15 wherein the plurality of condyle receivers are formed from multiple portions that make up the respective condyle receiver.
