A knotless suture system for anchoring tissue to bone is provided. The syst em includes a suture anchor configured to radially expand into bone. The suture anchor has a proximal end and a distal end with a bore formed therein. The system further includes a first loop of suture thread attached to the distal end of the suture anchor, a suture needle, and a second loop of suture thread attached to the needle and interlocked wi th the first loop of suture thread. The system also includes an expander pin that is configured and sized for insertion into the bore of the suture anchor, causing the anchor t o radially expand from a first outer diameter to a second outer diameter. A method is also provided by which a detached tissue may be securely attached to bone in an anatomical ly correct position without the need to tie a knot.
