Techniques and reconstruction systems for knotless tissue fixation using a driver with a cannulated interference device or fixation device preloaded on the shaft of the driver. An eyelet, adjustable in size, is formed of a loading suture provided at the distal end of the driver shaft. A working suture attached to the tissue to be fixed is passed through the eyelet. The size of the eyelet is adjusted by the user once the working suture is passed through the eyelet, to capture the working suture with the eyelet. The cannulated interference device is then advanced down the shaft to secure the working suture in a bone socket.
