An apparatus for anchoring at least two graft ligaments within a longitudinal bone tunnel includes a longitudinal sleeve having at least two radially spaced ligament-contacting surfaces located in lateral opposition to a sleeve inner lumen. The sleeve is configured for at least partial insertion into the bone tunnel with each graft ligament positioned laterally adjacent a different ligament-contacting surface. The graft ligaments are at least partially located between the bone tunnel and the sleeve. An actuating member has longitudinally separated proximal and distal actuating member ends. An asymmetrically offset profile is defined by at least one of the sleeve and the actuating member. The asymmetrically offset profile has a plurality of longitudinally spaced engagement thresholds. The actuating member is inserted longitudinally into the sleeve to cause frictional engagement of each graft ligament with both the bone tunnel and at least one ligament-contacting surface. The frictional engagement of each graft ligament is temporally spaced apart from the frictional engagement of at least one other graft ligament. The temporal spacing is provided by the plurality of engagement thresholds. A method of anchoring at least two longitudinally extending graft ligaments within a bone tunnel is also provided.

One or more techniques and/or systems are disclosed for a system for noninvasive adjusting fastener tensioning has an elongated shaft having a slot defined therein. The shaft has a first end oppositely disposed from the second end. An associated rod or rods may pass through each end. Selectively adjustable fasteners may have a plurality of magnets disposed in the head of the fastener. An external drive device generating a magnetic field may be used to rotate the fasteners via the magnets in the fastener head externally without the need for surgery. The fasteners may move in and out from the shaft and contact the rod to adjust tensioning.

An apparatus for anchoring elongate strands within a longitudinal tunnel is disclosed. At least two cams are arranged longitudinally adjacent each other along a longitudinal axis. A first anchor member includes a first cam-contacting surface and a first strand-contacting surface. The first cam-contacting surface is selectively operatively connected to a first cam. A second anchor member includes a second cam-contacting surface and a second strand-contacting surface. The second cam-contacting surface is selectively operatively connected to a second cam. An elongate strand is positioned between the tunnel wall and the first or second strand-contacting surfaces. Rotation of a selected cam causes the selected cam to selectively apply a force to a corresponding first or second cam-contacting surface to urge the corresponding first or second strand-contacting surface away from the longitudinal axis to produce frictional engagement of the elongate strand with both a tunnel wall and the first or second strand-contacting surface.
