Joint arthroplasty devices and surgical tools
View Patent ↗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.

2. The system of claim 1 , wherein the first mold has a shape that substantially conforms to a portion of a tibia.
3. The system of claim 1 , wherein the first 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 first 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 first 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 first 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 first mold includes one or more holes to guide one or more pins, wherein the one or more guide holes of the cutting guide is configured to accommodate the one or more pins.
8. The system of claim 1 , wherein the tool is a first tool, and further comprising: a second surgical tool having: a second mold including an internal surface that substantially conforms to the shape of a second surface of the ankle joint of the patient; and a second cutting guide, wherein the second guide includes anatomical information of the joint to facilitate the placement of a second component of an ankle repair system when the internal surface of the second mold is aligned with and substantially conforms to the shape of the second surface of the ankle joint.
9. The system of claim 8 , wherein the first mold has a shape that substantially conforms to a portion of a tibia.
10. The system of claim 8 , wherein the first mold has a shape that substantially conforms to a portion of cortical bone of the ankle joint of the patient.
11. The system of claim 8 , wherein the first mold has a shape that substantially conforms to a portion of an articular surface of the ankle joint of the patient.
12. The system of claim 8 , wherein the first mold has a shape that substantially conforms to a portion of cartilage of the ankle joint of the patient.
13. The system of claim 8 , wherein the first mold has a shape that substantially conforms to a portion of subchondral bone of the ankle joint of the patient.
14. The system of claim 8 , further comprising an ankle implant.
15. The system of claim 8 , further comprising an articular implant.
16. The system of claim 1 , further comprising an ankle implant.
17. The system of claim 1 , wherein the anatomical information is information regarding an axis associated with the ankle joint 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 guide defines at least in part a rotation of an ankle implant.
22. The system of claim 1 , wherein the guide defines at least in part an axial rotation of an ankle implant.
23. The system of claim 1 , wherein the guide defines a cut plane extending into the joint.
24. The system of claim 1 , wherein the mold and the cutting guide are integrally formed.
25. The system of claim 1 , wherein the mold and the cutting guide are separate components.
26. 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 of a joint of the patient; and a guide to guide a surgical instrument, wherein the guide includes 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 surface of the joint, wherein the joint of the patient is an ankle joint of the patient.
27. 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 a guide to guide a surgical instrument, wherein the guide includes 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 articular surface of the joint, wherein the joint of the patient is an ankle joint of the patient.
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 a first guide configured to guide a surgical instrument, wherein the guide includes first 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 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 a second guide configured to guide a surgical instrument, wherein the guide includes second 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 bone surface of the joint, wherein the joint of the patient is an ankle joint of the patient.
29. The surgical instrument of claim 28 , further comprising an articular implant.
30. The surgical instrument of claim 29 , wherein the first anatomical information includes rotational information of the articular implant.
