In one aspect of the invention, a cross-pin includes a distal portion having an axis, a distal end, and a proximal end. A proximal cylindrical portion includes a threaded exterior surface. A junction may be interposed between the distal and proximal portions to enable the proximal portion to rotate relative to the distal portion. In another aspect of the invention, a graft retaining system for retaining a graft in a bone tunnel includes a graft block having a proximal end and a distal end, and sized to fit within the bone tunnel. A cross pin transverse to the bone tunnel attaches the graft block adjacent the tunnel. An intermediate connector is attached to the graft block at a point distal to the cross pin and connects the graft to the graft block so as to apply compressive forces to the graft block.
