1. A sterile composite graft comprising:
- first and second bone blocks, each bone block defining a central through going bore having a cross section which will allow a ligament replacement to be passed there through and at least one longitudinal channel cut substantially parallel to the axis of the central through going bore in the exterior surface of said bone block and a ligament replacement mounted to said bone blocks, said ligament replacement extending through said central bore of said bone blocks and around said first and second bone blocks seated in said longitudinal channel.

Abstract
The invention is directed toward a bone block, a bone-tendon-bone assembly and method of tendon reconstruction in which at least one tendon replacement is extended between two bone blocks and fixed within each of two bone tunnels in the bones of a joint using interference screws. Each bone block has a central through going bore and at least one substantially parallel channel longitudinally cut in the exterior of the bone block body in which the ligament replacements are seated. One end of each bone block has a rounded recess leading from the central bore to the exterior parallel channel.
