A suture holding system including a suture and a block having first, second and third regions for receiving the suture, having proximal and distal ends, is provided. The suture is received in the first and second regions of the block, defining a first suture portion, and is then received in the third region before passing between the block and the first suture portion, defining a second suture portion. In this configuration, pulling on the distal end of the suture selectively locks the suture to block, whereas pulling on the proximal end of the suture allows the suture to advance freely in that direction. Suture holding system may also include a second block, being rotated 180 degrees with respect to the first block. A delivery device for implanting the suture holding system in soft tissue and methods for repairing a tear in soft tissue are also provided.
