Abstract

The present disclosure relates to an anchor assembly. The anchor assembly includes an anchor defining a cavity and an opening to the cavity and an insertion member configured for arrangement within the anchor cavity. The insertion member includes a body having a proximal end portion and a flat distal end portion, and a head coupled to the proximal end portion of the body. A method of tissue repair and other anchor assemblies are also disclosed.

Claims (11)

1. A method of tissue repairing tissue comprising:

inserting a first anchor into bone, the first anchor having a flexible member coupled thereto;

passing ends of the flexible member through the tissue;

passing at least one end of the flexible member through a transverse through hole extending through a second anchor, the second anchor further defining an anchor cavity and an opening to the anchor cavity;

placing the second anchor into the bone; and

placing an insertion member within the anchor cavity of the second anchor to secure the flexible member in the through hole and the tissue to the bone, the insertion member including a body having a proximal end portion and a flat distal end portion, and a head coupled to the proximal end portion of the body,

wherein the second anchor includes protrusions located on an outer surface of the second anchor and below openings of the through hole, the protrusions tapered along their lengths and extending away from the outer surface of the second anchor, the protrusions arranged on the outer surface such that non-tapered areas are located between the protrusions, wherein the non-tapered areas are rounded.

2. The method of claim 1 further comprising tensioning the flexible member before placing the insertion member within the anchor cavity.

3. The method of claim 1 further comprising moving the insertion member away from the through hole, tensioning the flexible member, and moving the insertion member back toward the through hole to resecure the flexible member in the through hole.

4. The method of claim 1 wherein the protrusions create paths in a wall of the bone when the second anchor is inserted into the bone.

5. The method of claim 4 wherein the paths allow the flexible member to slide through the second anchor when the second anchor is located in the bone.
