Abstract

A method-for reconstructing a ligament. In one form of the invention, there is disclosed a method for securing a graft ligament in a bone tunnel, the method comprising the steps of: (1) forming a first bone tunnel in a bone, and forming a second bone tunnel in the same bone, the second bone tunnel being transverse to, and intersecting, the first bone tunnel; (2) positioning a flexible member in the second transverse bone tunnel so that the flexible member extends across the first bone tunnel, and positioning the graft ligament in the first bone tunnel, independently of the flexible member, so that the graft ligament is looped over the flexible member; and (3) positioning a crosspin over the flexible member and in the second transverse bone tunnel so that the graft ligament is looped over, and may be supported by, the crosspin.

Claims

1. A method for securing a graft ligament in a bone tunnel, said method comprising the steps of:

(1) forming a first bone tunnel in a bone, and forming a second bone tunnel in the same bone, said second bone tunnel being transverse to, and intersecting, said first bone tunnel;

(2) positioning a flexible member in said second transverse bone tunnel so that said flexible member extends across said first bone tunnel, and positioning said graft ligament in said first bone tunnel, independently of said flexible member, so that said graft ligament is looped over said flexible member; and

(3) positioning a crosspin over said flexible member and in said second transverse bone tunnel so that said graft ligament is looped over, and may be supported by, said crosspin.

2. A method according to claim 1 wherein said step of positioning said graft ligament in said first bone tunnel, independently of said flexible member, comprises the sub-steps of:

(i) pulling a loop of said flexible member out of said first bone tunnel;

(b) pulling a loop of said graft ligament into said first bone tunnel so that said loop of graft ligament extends past the intersection of said second transverse bone tunnel with said first bone tunnel;

(c) positioning said loop of said flexible member within said loop of graft ligament; and

(d) pulling said flexible member straight so as to eliminate said loop of said flexible member.

3. A method according to claim 2 wherein said sub-step of pulling said loop of said graft ligament into said first bone tunnel comprises the sub-sub-steps of:

(i) attaching said loop of said graft ligament to a pulling member; and

(ii) passing said pulling member out the far said of said first bone tunnel.

4. A method for securing a graft ligament in a bone tunnel, said method comprising the steps of:

(1) forming a first bone tunnel in a bone, and forming a second bone tunnel in the same bone, said second bone tunnel being transverse to, and intersecting, said first bone tunnel;

(2) positioning a flexible member in said second transverse bone tunnel so that said flexible member extends across said first bone tunnel;

(3) pulling a loop of said flexible member out of said first bone tunnel;

(4) pulling a loop of said graft ligament into said first bone tunnel so that said loop of graft ligament extends past the intersection of said second transverse bone tunnel with said first bone tunnel;

(5) positioning said loop of said flexible member within said loop of graft ligament;

(6) pulling said flexible member straight so as to eliminate said loop of said flexible member; and

(7) positioning a crosspin over said flexible member and in said second transverse bone tunnel so that said graft ligament is looped over, and may be supported by, said crosspin.
