Methods and systems for knotless suture anchoring

A method of performing a surgical repair, comprising:

• distally driving an anchor assembly comprising a proximal anchor body mated to a proximal end of a distal anchor body of the anchor assembly into a hole in a bone, the proximal anchor body having at least one suture passed through at least one opening formed through at least one side wall of the proximal anchor body, the suture being passed through the opening such that terminal end portions of the suture pass alongside a driver shaft removably attached to the anchor assembly, the suture having a portion thereof that is attached to soft tissue;
• and rotating the distal anchor body to cause the distal anchor body to move proximally towards the proximal anchor body such that a proximal portion of the distal anchor body is received within the proximal anchor body so as to occlude the opening and thereby cause the suture to be secured between an inner wall of the proximal anchor body and an outer wall of the distal anchor body.
