Implant and method for repair of the anterior cruciate ligament
Described herein are methods and devices for use in repair of a patient's anterior cruciate ligament (ACL). These methods (and devices for performing them) allow the repair, rather than merely replacement, of the ACL. For example, described herein are anchoring devices that may be inserted into a bone and may anchor a scaffolding/support (e.g., graft) material within the bone so that the torn or damaged end of the ACL may be secured to the scaffolding/support material within the femoral notch. These anchoring devices and method of using them are particularly well suited for use with the continuous suture passers described herein, since these suture passers may allow access to previously inaccessible regions of the knee (or other body regions).
1. A method for repairing a torn ACL within the femoral notch, the method comprising:
anchoring a graft within the femoral notch;
securing a torn end of the ACL to a suture and pulling the suture through the femur to position the torn end of the ACL adjacent to the graft; and
suturing the torn end of the ACL to the graft within the femoral notch.
2. The method of claim 1 , wherein anchoring a graft comprises securing an anchor to which a graft has been coupled within the femur so that a proximal end of the graft extends from the femur.
3. The method of claim 1 , wherein anchoring a graft comprises driving a guidewire through the femur and drilling an opening to hold a graft anchor; and securing an anchor coupled to a graft within the opening over the guidewire.
4. The method of claim 3 , wherein the anchor is secured by screwing the anchor into the opening.
5. The method of claim 1 , wherein suturing the torn end of the ACL comprises passing a suture through the graft and the ACL multiple times.
6. The method of claim 1 , wherein suturing the torn end of the ACL comprises passing a suture through the graft and the ACL multiple times with a continuous suture passer without removing the suture passer from the tissue.
7. The method of claim 1 , further comprising securing the torn end of the ACL to a suture and pulling the suture through the femur to anatomically tension the ACL adjacent to the graft.
8. A method for repairing a torn ACL within the femoral notch, the method comprising:
anchoring a graft within the femoral notch;
positioning a torn end of the ACL adjacent to the graft;
wherein positioning comprises securing a suture to the torn end of the ACL;
pulling the suture through a tunnel in the femoral notch to position the torn end of the ACL adjacent to the graft; and
percutaneously suturing the torn end of the ACL to the graft within the femoral notch.
9. The method of claim 8 , further comprising anchoring the torn end of the ACL to the femoral notch with a suture before percutaneously suturing the torn end of the ACL to the graft.
10. The method of claim 8 , further comprising drilling a tunnel through the femoral arch for anchoring the torn ACL.
11. The method of claim 8 , wherein anchoring the graft within the femoral notch comprises anchoring the graft within a tunnel drilled through the femoral arch.
12. A method for repairing a torn ACL within the femoral notch, the method comprising:
drilling a tunnel through a portion of the femoral notch;
anchoring a graft within the tunnel through the femoral notch, wherein the graft extends from the tunnel;
pulling a suture connected to a torn end of the ACL through the tunnel through the femoral arch to position the torn end of the ACL adjacent to the graft;
anchoring the suture connected to the torn end of the ACL; and
percutaneously suturing the torn end of the ACL to the graft within the femoral notch.
