    • A graft clamp for securing a tissue graft located within a tunnel in bone includes a first member having a first clamping face, and a second member having a second clamping face. The first and second members are sized for positioning at an opening of the tunnel such that the first and second clamping faces are positioned substantially transversely to a bone surface defining the tunnel opening to secure the tissue graft therebetween. The clamping faces have ridges. The first member includes a spike for insertion into the bone, and a collar for insertion into the opening of the tunnel. An attaching element, for example, a screw, attaches the second member to the first member. The clamping faces are located exterior to the tunnel with the attaching element extending into the tunnel. The position of the first member and the second member at the tunnel opening is maintained at least partially by tension applied to the tissue graft.
    • 用于固定位于骨内隧道内的组织移植物的移植物夹具包括具有第一夹紧面的第一构件和具有第二夹紧面的第二构件。 第一和第二构件的尺寸适于定位在隧道的开口处,使得第一和第二夹紧面基本上横向于限定隧道开口的骨表面定位,以将组织移植物固定在其间。 夹紧面有脊。 第一构件包括用于插入到骨中的钉,以及用于插入隧道开口的套环。 附接元件,例如螺钉,将第二构件附接到第一构件。 夹紧面位于隧道外部,附着元件延伸到隧道内。 第一构件和第二构件在隧道开口处的位置至少部分地由施加到组织移植物的张力保持。
