Adjustable and fixed assembled bone-tendon-bone graft

An adjustable bone-tendon-bone implant comprising:

• a length of soft tissue having a first end and a second end,
• a first bone component, and
• a second bone component
• wherein said second bone component slideably attaches to said length of soft tissue and wherein said first bone component comprises a first intermediate bone block and a second intermediate bone block, said first intermediate bone block and said second intermediate bone block sandwiching said first end of said length of soft tissue therebetween;
• and
• wherein said first intermediate bone block comprises a first tissue engaging surface that contacts one side of said soft tissue and said second intermediate bone block comprises a second tissue engaging surface that contacts an opposing side of said soft tissue;
• and
• wherein said first tissue engaging surface of said first intermediate bone block comprises at least one compression surface and from one to ten channels;
• wherein said one to ten channels have an undercut cross-sectional profile and are laid out across said tissue engaging surface in a nested configuration along a direction of pull of said soft tissue;
• and
• further wherein said second bone component comprises at least one portal through said second bone component from a top side to a bottom side and wherein said length of soft tissue goes through said portal of said second bone component
• wherein said first bone component, said second bone component and said length of soft tissue comprise allograft tissue, autograft tissue, xenograft tissue, an engineered construct of natural or synthetic origin or a combination thereof.
