Method and apparatus for coupling anatomical features
A method of coupling a first portion of an anatomy to a second portion of the anatomy includes coupling first and second bones of the anatomy with a bone-tendon-bone implant. The bone-tendon-bone implant has a first bone end, a second bone end and a replacement tendon between the first and second bone ends. The first and second bone ends are positioned in corresponding first and second bores of the first and second bones. The first bone end is secured to the first bone with a first bone anchor. A second anchor coupled to the bone-tendon-bone implant is passed through and outside the second bore. The second anchor is coupled to an adjustable suture construct having two adjustable suture loops. Tensioning at least one of first and second ends of the adjustable suture construct tensions the replacement tendon and positions the first bone relative to the second bone.
