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.
1. A method for surgically repairing a joint of a patient using a patient specific instrument, comprising:
mating a patient specific surface portion of the instrument to a corresponding articular surface portion including cartilage of the joint of the patient; and
drilling a hole in the joint of the patient along a path defined by a drill hole in the instrument, wherein the drill hole includes anatomical information of the joint to define the path and thereby facilitate the placement of an articular repair system.
2. The method of claim 1 , further comprising drilling a second hole in the joint of the patient along a second path defined by a second drill hole in the instrument, wherein the second drill hole includes anatomical information of the joint to define the second path, wherein a combination of the drill hole and the second drill hole sets a rotation of an implant of the articular repair system.
3. The method of claim 1 , wherein the joint is a knee joint having a femoral condyle, and further comprising making at least one bone cut in the femoral condyle to define an implant position, wherein the at least one bone cut is based at least in part on a location of the drill hole.
4. The method of claim 3 , wherein the implant position in part corrects at least one of a varus or a valgus condition of the knee joint.
5. The method of claim 3 , wherein the implant position in part corrects a deformity of the knee joint.
6. The method of claim 1 , wherein the joint is a knee joint having a tibia, and further comprising making at least one bone cut in the tibia to define an implant position, wherein the at least one bone cut is based at least in part on a location of the drill hole.
7. The method of claim 6 , wherein the implant position in part corrects at least one of a varus or a valgus condition of the knee joint.
8. The method of claim 6 , wherein the implant position in part corrects a deformity of the knee joint.
9. A method for surgically repairing a joint of a patient using a patient specific instrument, comprising:
mating a patient specific surface of the instrument to a corresponding cartilage surface portion of the joint of the patient; and
drilling a hole in the joint of the patient along a path defined by a drill hole in the instrument, wherein the drill hole includes anatomical information of the joint to define the path and thereby facilitate the placement of an articular repair system.
10. The method of claim 9 , further comprising drilling a second hole in the joint of the patient along a second path defined by a second drill hole in the instrument, wherein the second drill hole includes anatomical information of the joint to define the second path, wherein a combination of the drill hole and the second drill hole sets a rotation of an implant of the articular repair system.
11. The method of claim 9 , wherein the joint is a knee joint having a femoral condyle, and further comprising making at least one bone cut in the femoral condyle to define an implant position, wherein the at least one bone cut is based at least in part on a location of the drill hole.
12. The method of claim 11 , wherein the implant position in part corrects at least one of a varus or a valgus condition of the knee joint.
13. The method of claim 11 , wherein the implant position in part corrects a deformity of the knee joint.
14. The method of claim 9 , wherein the joint is a knee joint having a tibia, and further comprising making at least one bone cut in the tibia to define an implant position, wherein the at least one bone cut is based at least in part on a location of the drill hole.
15. The method of claim 14 , wherein the implant position in part corrects at least one of a varus or a valgus condition of the knee joint.
16. The method of claim 14 , wherein the implant position in part corrects a deformity of the knee joint.
17. A method for surgically repairing a joint of a patient using a patient specific instrument, comprising:
mating a patient specific surface portion of the instrument to a corresponding articular surface portion of the joint of the patient;
drilling a hole in the joint of the patient along a path defined by a drill hole in the instrument, wherein the drill hole includes anatomical information of the joint to define the path and thereby facilitate the placement of an articular repair system;
aligning a pin to provide a predetermined orientation relative to the patient specific surface; and
attaching a cutting block to the pin to provide a cutting path having a predetermined orientation relative to the joint of the patient.
18. The method of claim 17 , wherein a combination of the drill hole and the cutting path sets a rotation of an implant.
19. The method of claim 17 , wherein the joint is a knee joint having a femoral condyle, and further comprising making at least one bone cut in the femoral condyle to define an implant position, wherein the at least one bone cut is based at least in part on a location of the drill hole.
20. The method of claim 19 , wherein the implant position in part corrects at least one of a varus or a valgus condition of the knee joint.
21. The method of claim 19 , wherein the implant position in part corrects a deformity of the knee joint.
22. The method of claim 17 , wherein the joint is a knee joint having a tibia, and further comprising making at least one bone cut in the tibia to define an implant position, wherein the at least one bone cut is based at least in part on a location of the drill hole.
23. The method of claim 22 , wherein the implant position in part corrects at least one of a varus or a valgus condition of the knee joint.
24. A method for surgically repairing a joint of a patient using a patient specific instrument, comprising:
mating a patient specific surface of the instrument to a corresponding cartilage surface portion of the joint of the patient;
drilling a hole in the joint of the patient along a path defined by a drill hole in the instrument, wherein the drill hole includes anatomical information of the joint to define the path and thereby facilitate the placement of an articular repair system;
aligning a pin to provide a predetermined orientation relative to the patient specific surface; and
attaching a cutting block to the pin to provide a cutting path having a predetermined orientation relative to the joint of the patient.
25. The method of claim 24 , wherein a combination of the drill hole and the cutting path sets a rotation of an implant.
26. The method of claim 24 , wherein the joint is a knee joint having a femoral condyle, and further comprising making at least one bone cut in the femoral condyle to define an implant position, wherein the at least one bone cut is based at least in part on a location of the drill hole.
27. The method of claim 26 , wherein the implant position in part corrects at least one of a varus or a valgus condition of the knee joint.
28. The method of claim 26 , wherein the implant position in part corrects a deformity of the knee joint.
29. The method of claim 24 , wherein the joint is a knee joint having a tibia, and further comprising making at least one bone cut in the tibia to define an implant position, wherein the at least one bone cut is based at least in part on a location of the drill hole.
30. The method of claim 29 , wherein the implant position in part corrects at least one of a varus or a valgus condition of the knee joint.
