An adjustable anchor system for securing tissue to bone, including an anchor having at least one passage extending from a proximal end toward a distal end. The passage defines a restriction such as a restricted opening. The anchor has at least one bone-engaging feature disposed between the proximal and distal ends. The system further includes a first material formed as a closed loop and capable of being placed through a portion of the tissue, and a second filament having a terminal end, a post limb and a sliding knot tied between the terminal end and the post limb to establish an elongated, adjustable-length loop which extends beyond the proximal end of the anchor and captures the closed loop of the first material. The knot of the second filament is restrained by the restricted opening when tension is applied as desired to the post limb to shorten the elongated loop to draw the tissue toward the anchor.La présente invention se rapporte à un système d'ancrage ajustable qui permet de fixer un tissu à un os et qui comprend une ancre ayant une boucle de suture pliable fixée à cette dernière et une suture de tissu raccordée à la boucle de suture pliable. Après que la suture de tissu est chargée dans le tissu et que l'ancre est implantée dans l'os, la boucle pliable est pliée afin de tendre la suture du tissu.
