Z-shaped button for tissue repair

A Z-shaped button with a flexible strand or loop (which may have a fixed or adjustable length) for tissue repair and reconstruction in bone tunnels. The Z-shaped button has a distinctive Z-shape or an S-shape configuration, that allows a smaller length button to achieve comparable contact area as with a longer length button. The Z-shaped allows for truncated flipping distance yet permits maximum cortical bone contact. The continuous loop/Z-shaped button construct may be used for fixation of bone to bone, or of soft tissue to bone.
