Abstract
Disclosed herein are tools for repairing articular surfaces repair materials and for repairing an articular surface. 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.
Claims67
A system for articular repair, the system comprising:
- a first template having a first surface and a second surface, the first surface conforming with, and substantially a negative of, at least a portion of a first side of a joint;
- a second template having a third surface that conforms with, and is substantially a negative of, a portion of the first side of the joint, the second template including at least one guide for guiding a surgical instrument in making a cut on the first side of the joint;
- and
- an attachment mechanism for attaching the second template to the first template.
A system for articular joint repair, the system comprising:
- a first template having a first surface and a second surface, the first surface substantially a negative of at least a portion of the tibial plateau;
- a second template having a third surface that is substantially a negative of a portion of the tibia, the second template including at least one guide for guiding a surgical instrument in making a cut on the tibia;
- and
- an attachment mechanism for attaching the second template to the first template.
A system for articular repair, the system comprising:
- a first template having a first surface and a second surface, the first surface substantially matching at least a portion of the tibial plateau, the first template including a medial edge that corresponds to a predetermined location for a vertical tibial cut.
A kit for testing at least one of ligament balancing and ligament tension, the kit comprising:
- a first template having at least one surface substantially conforming with at least a portion of a first articular joint surface;
- wherein the template is configured for placement on the first articular joint surface and between the first articular joint surface and a second articular joint surface, the template having a predefined thickness configured to provide a physical spacer for assessing at least one of ligament balance and ligament tension during a surgical procedure.
A method of partial or total knee replacement or resurfacing, the method comprising:
- positioning a first surface of a first instrument onto at least a portion of the tibial plateau, the first surface being substantially a negative of at least a portion of the tibial plateau;
- cross-referencing a second instrument to the first instrument to align position of the second instrument on the tibia, the second instrument including at least one surgical cut guide;
- and
- directing a cut using the at least one surgical guide of the second of the second instrument.
A method for testing at least one of ligament balancing and ligament tension of a joint, the method comprising:
- inserting a first template having a first surface onto a first joint surface, the first surface substantially conforming to the first joint surface;
- and
- inserting a second template onto the first joint surface, the second template having a first surface that conforms with, and is substantially a negative of, the first joint surface, the second template having a thickness that varies from the first template.
A system for articular repair, the system comprising:
- a first template having a first surface and a second surface, the first surface substantially conforming with, and substantially a negative of, at least a portion of a distal femur;
- a second template having a third surface that conforms with, and is substantially a negative of, a portion of the distal femur, the second template including at least one guide for guiding a surgical instrument in making a cut on the distal femur;
- and
- an attachment mechanism for attaching the second template to the first template.
A system for articular repair, the system comprising:
- a first template having a first surface and a second surface, the first surface substantially conforming to at least a portion of the distal femur, the first template including a medial edge that corresponds to a predetermined location for a vertical femoral or tibial cut.
