An apparatus for arthroscopic repair of tissue comprising: first and second fixation members, each of the first and the second fixation members having a first surface (114, 124), an opposing second surface (112, 122), first (116, 126) and second (118, 128) through openings defined between the first surface and the second surface; a flexible element coupling the first and the second fixation members, the flexible element having a first end, a second end and a length therebetween, the length extending from the first end, in order, along a first end section, through the first opening in the first fixation member from the respective first surface to the respective second surface, through the first opening in the second fixation member from the respective second surface to the respective first surface, through the second opening in the second fixation member from the respective first surface to the respective second surface, through the second opening in the first fixation member from the respective second surface to the respective first surface, and along a second end section; the first fixation member further comprising a third through opening defined between the respective first and second surface; said apparatus being characterized in that a sliding, locking knot is formed between the first end section and the second end section, the first end section positioned slidably through the knot, the first end section extending from the knot and through the third opening from the first surface to the second surface; whereby tension applied to the first end section passing through the third opening causes the first end section to slide through the sliding, locking knot, thereby approximating the first and second fixation members, and whereby the sliding, locking knot substantially prevents the first end section from sliding in the opposite direction, thereby substantially preventing re-separation of the first and second fixation member. first and second fixation members, each of the first and the second fixation members having a first surface (114, 124), an opposing second surface (112, 122), first (116, 126) and second (118, 128) through openings defined between the first surface and the second surface; a flexible element coupling the first and the second fixation members, the flexible element having a first end, a second end and a length therebetween, the length extending from the first end, in order, along a first end section, through the first opening in the first fixation member from the respective first surface to the respective second surface, through the first opening in the second fixation member from the respective second surface to the respective first surface, through the second opening in the second fixation member from the respective first surface to the respective second surface, through the second opening in the first fixation member from the respective second surface to the respective first surface, and along a second end section; the first fixation member further comprising a third through opening defined between the respective first and second surface; said apparatus being characterized in that a sliding, locking knot is formed between the first end section and the second end section, the first end section positioned slidably through the knot, the first end section extending from the knot and through the third opening from the first surface to the second surface; whereby tension applied to the first end section passing through the third opening causes the first end section to slide through the sliding, locking knot, thereby approximating the first and second fixation members, and whereby the sliding, locking knot substantially prevents the first end section from sliding in the opposite direction, thereby substantially preventing re-separation of the first and second fixation member.
