Abstract
Abstract A knotless suture anchor assembly for the attachment or reattachment or repair of tissue to a bone mass. The assembly allows for an endoscopic or open surgical procedure to take place without the requirement of tying a knot for reattachment of tissue to bone mass. A spike member is inserted through tissue mass through a loop and inserted into a dowel-like hollow anchoring sleeve which has been inserted into a bone mass. The spike member is securely fastened or attached to the anchoring sleeve with a ratcheting mechanism thereby pulling or adhering (attaching) the tissue to the bone mass.
