Abstract

A method and apparatus for fixing a ligament in a bone tunnel by cross-pinning the ligament in the bone tunnel.

Claims (8)

1. A graft ligament having a first end and second end, said first end and said second end defining a first longitudinal axis, and said graft ligament having a substantially uniform cross-sectional thickness along said first longitudinal axis between said first end and said second end, said graft ligament comprising:

a tendon having a third end and a fourth end, said third end and said fourth end defining a second longitudinal axis therebetween, said tendon having a non-uniform cross-sectional thickness along said second longitudinal axis between said third end and said fourth end, and said tendon having a first portion, a second portion, and a third portion along said second longitudinal axis between said third end and said fourth end; and

a securing material securing at least one section of said first portion, said second portion, and said third portion with another at least one section of said first portion, said second portion, and said third portion so as to form said third end and said fourth end, respectively, and so as to form said graft ligament with a substantially uniform cross-sectional thickness along said first longitudinal axis between said first end and second end;

wherein said tendon has said first portion, said second portion, and said third portion in series from said third end to said fourth end, and further wherein said second portion has a given mean cross-sectional thickness, and said first portion and said third portion each have a smaller mean cross-sectional thickness than said given mean cross-sectional thickness;

wherein said first portion and said third portion are each folded against said second portion and sutured thereto, respectively;

wherein said second portion is folded against itself, a bone core is disposed between said first portion and said third portion, and said first portion and said third portion are secured together with said bone core disposed therebetween.

2. A graft ligament according to claim 1 , wherein said folded second portion, forming a first Segment and second segment, is sutured therebetween.

3. A graft ligament according to claim 1 , further comprising at least two of said tendons secured together to form said graft ligament.
