Z-shaped button for tissue repair

Techniques and reconstruction systems for tissue repairs employing a Z-shaped button with a flexible strand or loop (which may have a fixed or adjustable length). 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 button 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.
