Abstract

Disclosed herein are methods, compositions and tools for repairing articular surfaces repair materials and for repairing an articular surface. The articular surface repairs are customizable or highly selectable by patient and geared toward providing optimal fit and function. The surgical tools are designed to be customizable or highly selectable by patient to increase the speed, accuracy and simplicity of performing total or partial arthroplasty.

Claims (33)

1. A system for surgically repairing a joint of a patient, comprising:

a mold having an internal surface that substantially conforms to the shape of a surface of the joint of the patient; and one or more holes configured as alignment guides to guide a surgical instrument to create one or more pin holes to accommodate one or more surgical pins configured as alignment guides to guide a second surgical tool, wherein the one or more holes include anatomical information of the joint to facilitate the placement of an articular repair system when the internal surface of the mold is aligned with and substantially conforms to the shape of the surface of the joint, wherein the joint of the patient is an ankle joint.

2. The system of claim 1 , wherein the mold has a shape that substantially conforms to a portion of a tibia of the ankle joint.

3. The system of claim 1 , wherein the mold has a shape that substantially conforms to a portion of cortical bone of the ankle joint of the patient.

4. The system of claim 1 , wherein the mold has a shape that substantially conforms to a portion of an articular surface of the ankle joint of the patient.

5. The system of claim 1 , wherein the mold has a shape that substantially conforms to a portion of cartilage of the ankle joint of the patient.

6. The system of claim 1 , wherein the mold has a shape that substantially conforms to a portion of subchondral bone of the ankle joint of the patient.

7. The system of claim 1 , wherein the mold is a first mold, and further comprising a second mold having an internal surface that substantially conforms to the shape of a second surface of the ankle joint of the patient.

8. The system of claim 7 , wherein the first mold has a shape that substantially conforms to a portion of a tibia of the ankle joint of the patient.

9. The system of claim 7 , wherein the first mold has a shape that substantially conforms to a portion of cortical bone of the ankle joint of the patient.

10. The system of claim 7 , wherein the first mold has a shape that substantially conforms to a portion of an articular surface of the ankle joint of the patient.

11. The system of claim 7 , wherein the first mold has a shape that substantially conforms to a portion of cartilage of the ankle joint of the patient.

12. The system of claim 7 , wherein the first mold has a shape that substantially conforms to a portion of subchondral bone of the ankle joint of the patient.

13. The system of claim 7 , further comprising an ankle implant.

14. The system of claim 7 , further comprising an articular implant.

15. The system of claim 1 , further comprising an ankle implant.

16. The system of claim 1 , further comprising an articular implant.

17. The system of claim 1 , wherein the anatomical information is information regarding an axis associated with the ankle of the patient.

18. The system of claim 1 , wherein the anatomical information is information regarding a tibial axis of the patient.

19. The system of claim 1 , wherein the anatomical information is information regarding a deformity of the joint of the patient.

20. The system of claim 1 , wherein the anatomical information is information regarding an alignment of the joint of the patient.

21. The system of claim 1 , wherein the one or more holes define at least in part a rotation of an ankle implant.

22. The system of claim 1 , wherein the one or more holes define at least in part an axial rotation of an ankle implant.

23. The system of claim 1 , wherein a width of the one or more holes is smaller than a dimension of the implant.

24. A system for surgically repairing a joint of a patient, comprising:

a mold having an internal surface that substantially conforms to the shape of a surface of the bone of a joint of the patient; and one or more holes configured as alignment guides to guide a surgical instrument, wherein the one or more holes include rotational information of the joint to facilitate the placement of an articular repair system when the internal surface of the mold is aligned with and substantially conforms to the shape of the bone surface of the joint, wherein the joint of the patient is an ankle joint of the patient.

25. A system for surgically repairing a joint of a patient, comprising: a mold having an internal surface that substantially conforms to the shape of an articular surface of a joint of the patient; and one or more holes configured as alignment guides to guide a surgical instrument, wherein the one or more holes include rotational information of the joint to facilitate the placement of an articular repair system when the internal surface of the mold is aligned with and substantially conforms to the shape of the bone surface of the joint, wherein the joint of the patient is an ankle joint of the patient.

26. The system of claim 25 , further comprising an articular implant.

27. The system of claim 26 , wherein the rotational information includes rotational information of the articular implant.

28. A system for surgically repairing a joint of a patient, comprising:

a first surgical tool having a first mold having an internal surface that substantially conforms to the shape of a first surface of a joint of the patient; and first and second holes configured as alignment guides to guide a surgical instrument, wherein the first and second holes include first anatomical information of the joint to facilitate the placement of an articular repair system when the internal surface of the first mold is aligned with and substantially conforms to the shape of the bone surface of the joint; and a second surgical tool having a second mold having an internal surface that substantially conforms to the shape of a second surface of the joint of the patient; and third and fourth holes configured as alignment guides to guide a surgical instrument, wherein the third and fourth holes include second anatomical information of the joint to facilitate the placement of an articular repair system when the internal surface of the second mold is aligned with and substantially conforms to the shape of the bone surface of the joint, wherein the joint of the patient is an ankle joint of the patient.

29. The system of claim 28 , further comprising an articular implant.

30. The system of claim 29 , wherein the first anatomical information includes rotational information of the articular implant.
