摘要
Suture anchor without knots (120; 198; 210; 238; 320) for implantation in a hole in the bone, comprising: an outer tubular element (136; 200; 300) having a distal end (128), an end proximal (138; 232), an outer wall (180; 236) configured to retain the suture anchor without knots in the hole in the bone, and an inner wall (176); an inner element (134; 260; 270; 290) which is rotatably disposed within the outer tubular element, the inner element having an outer diameter; and the inner element and the outer tubular element each having an opening (164; 130) for receiving a suture thread (122); characterized in that the outer diameter of the inner element is selected, such that as the inner element that presents the suture thread (122) received by its opening (164) is rotated, the thread (122) is pulled suture through the opening (130) of the outer tubular element and is wound on the inner element, thereby increasing the effective diameter of the inner element as the suture thread (122) wound in contact with the inner wall of the outer tubular element, said contact exerting an inward force on the wound suture thread (122) to keep it in position in the inner element.
