Abstract

A template for use in forming an insertion for cruciate ligament reconstruction surgery includes a template body that is inserted into the knee and positioned on a wall of the femoral notch of the knee. The template body includes openings sized and positioned to receive guidewires and to direct the guidewires into the wall of the femoral notch.

Claims

1. A template for use in forming an insertion for cruciate ligament reconstruction surgery, the template comprising a template body configured to be inserted into a knee and positioned on a wall of a femoral notch of the knee, the template body including openings sized and positioned to receive guidewires and to direct the guidewires into the wall of the femoral notch, wherein the openings are defined as recesses in a perimeter of the template body.

4. The template of claim 1, wherein the recesses are defined so that the guidewires are removable through the perimeter of the template body.

5. The template of claim 4, wherein the recesses include narrowed portions having widths slightly smaller than the diameters of the guidewires so that the guidewires are maintained in the recesses until a force sufficient to deform the guidewires or the template body is applied to remove the guidewires through the perimeter of the template body.

6. The template of claim 1, further comprising an arm extending from the template body, the arm being positioned and configured to include a portion that remains outside of the knee when the template body is inserted into the knee.

8. The template of claim 6, further comprising a handle connected to the arm.

9. The template of claim 8, wherein a first end of the handle is connected to the arm, the template further comprising a second arm extending from a second end of the handle.

2. A template for use in forming an insertion for cruciate ligament reconstruction surgery, the template comprising a template body configured to be inserted into a knee and positioned on a wall of a femoral notch of the knee, the template body including openings sized and positioned to receive guidewires and to direct the guidewires into the wall of the femoral notch, wherein at least one of the openings is defined as a recess in a perimeter of the template body.

3. The template of claim 2, wherein the openings are defined as recesses in a perimeter of the template body.

7. A template for use in forming an insertion for cruciate ligament reconstruction surgery, the template comprising:

a template body configured to be inserted into a knee and positioned on a wall of a femoral notch of the knee, the template body including openings sized and positioned to receive guidewires and to direct the guidewires into the wall of the femoral notch;

an arm extending from the template body, the arm being positioned and configured to include a portion that remains outside of the knee when the template body is inserted into the knee; and

depth marks defined on the arm for use in positioning the template body on the wall of the femoral notch.

10. A template for use in forming an insertion for cruciate ligament reconstruction surgery, the template comprising:

a template body configured to be inserted into a knee and positioned on a wall of a femoral notch of the knee, the template body including openings sized and positioned to receive guidewires and to direct the guidewires into the wall of the femoral notch;

a first arm extending from the template body, the first arm being positioned and configured to include a portion that remains outside of the knee when the template body is inserted into the knee;

a handle having a first end and a second end, the first end being connected to the first arm;

a second arm extending from a second end of the handle; and

a second template body positioned at an end of the second arm, the second template body being configured to be inserted into the knee and positioned on the wall of the femoral notch and including openings sized and positioned to receive guidewires and to direct the guidewires into the wall of the femoral notch.

11. The template of claim 10, wherein the openings of the first template body are formed as recesses on a side of the first template body positioned further from the handle and the openings of the second template body are formed as recesses on a side of the second template body positioned closer to the handle.

12. The template of claim 10, wherein the first template body includes a number of openings that differs from a number of opening included on the second template body.

13. The template of claim 10, wherein openings of the first template body are positioned closer together than are openings of the second template body.

14. A method of forming an insertion for cruciate ligament reconstruction surgery, the method comprising:

inserting a template into a knee and positioning the template on a wall of a femoral notch of the knee, the template including openings sized and positioned to receive guidewires and to direct the guidewires into the wall of the femoral notch;

inserting a first guidewire into the wall of the femoral notch using a first opening in the template;

inserting a second guidewire into the wall of the femoral notch using a second opening in the template;

drilling a first hole in the wall of the femoral notch using the first guidewire; and

drilling a second hole in the wall of the femoral notch using the second guidewire.

15. The method of claim 14, further comprising removing the template from the knee after inserting the second guidewire.

16. The method of claim 15, wherein drilling the first hole comprises drilling the first hole after inserting the first guidewire and before inserting the second guidewire.

17. The method of claim 14, wherein drilling the first hole comprises using a cannulated drill bit having an opening through which the first guidewire passes.

18. The method of claim 14, wherein drilling the first hole comprises drilling the first hole from the wall of the femoral notch.

19. The method of claim 18, wherein drilling the first hole comprises drilling the first hole only a limited distance into, and not completely through, the femur.

20. The method of claim 14, wherein the first and second holes are separated by a bony bridge.

21. The method of claim 20, wherein the first and second holes overlap.

22. The method of claim 21, further comprising directing a dilator into the overlapping first and second holes to create a cavity in the wall of the femoral notch.

23. The method of claim 14, further comprising attaching a first portion of a ligament graft to the first hole when the knee is in a first position and attaching a second portion of the ligament graft to the second hole when the knee is in a second, substantially different position.

24. The method of claim 14, wherein inserting the first guidewire comprises inserting the first guidewire into the wall of the femoral notch through the first opening in the template, and inserting the second guidewire comprises inserting the second guidewire into the wall of the femoral notch through the second opening in the template.

25. The method of claim 14, wherein inserting the first guidewire comprises using the first opening in the template to mark a guidewire location and inserting the first guidewire using the marked guidewire location.

26. The method of claim 25, wherein inserting the second guidewire comprises using the second opening in the template to mark a second guidewire location and inserting the second guidewire using the marked second guidewire location.

27. The method of claim 25, wherein marking the guidewire location comprises using electro-cautery techniques.

28. A method of forming a cavity for cruciate ligament reconstruction surgery, the method comprising:

inserting a first guidewire into a femur;

inserting a second guidewire into the femur using a device configured to space the second guidewire a predetermined distance from a location defined by the first guidewire;

drilling a first hole in the femur using the first guidewire; and

drilling a second hole in the femur using the second guidewire.

29. The method of claim 28, wherein the device comprises a template body including openings sized and positioned to receive the guidewires and to direct the guidewires into the wall of the femoral notch.

30. The method of claim 28, wherein drilling the first hole comprises drilling the first hole after inserting the first guidewire and before inserting the second guidewire.

31. The method of claim 30, wherein inserting the second guidewire comprises inserting the second guidewire using a device configured to space the second guidewire a predetermined distance from the first hole.
