## Abstract

Surgical constructs, assemblies, kits and methods of tissue fixation are disclosed. Glenoid augmentation is conducted with one or more soft tissue grafts placed on the anterior glenoid to fill a glenoid defect. Knotted or knotless suture anchors can deliver and fixate the soft tissue graft within the glenoid bone defect. Suture anchors can also secure the native ligament to the soft tissue graft and provide stability to the shoulder joint. Soft suture anchors can deliver and fixate a soft tissue graft within the bone defect. The native soft tissue can be repaired over top of the soft tissue graft into its anatomical position.

## Claims

### Claim 1

A repair system for glenoid augmentation, comprising:
one or more soft tissue grafts placed within a glenoid bone loss defect, wherein the one or more soft tissue grafts are dimensioned to follow a contour of the glenoid bone loss defect and to fill the glenoid bone loss defect, wherein at least one of the one or more soft tissue grafts is folded at least once; and
at least one fixation device attached to the one or more soft tissue grafts, wherein the at least one fixation device is secured into the glenoid and the one or more soft tissue grafts are secured onto the glenoid.

### Claim 2 (depends on 1)

The repair system of claim 1, wherein the one or more soft tissue grafts are formed of a plurality of grafts.

### Claim 3 (depends on 2)

The repair system of claim 2, wherein each of the plurality of grafts has a shape and dimensions about equal to shapes and dimensions of the others of the plurality of grafts.

### Claim 4 (depends on 2)

The repair system of claim 2, wherein one of the plurality of grafts has a thickness greater than thicknesses of the others of the plurality of grafts.

### Claim 5 (depends on 1)

The repair system of claim 1, wherein the at least one fixation device is a knotted or knotless suture anchor.

### Claim 6 (depends on 1)

The repair system of claim 1, wherein the at least one fixation device is a soft suture anchor comprising a flexible tubular sleeve or sheath and a plurality of flexible strands extending through a passage of the flexible tubular sleeve or sheath.

### Claim 7 (depends on 1)

The repair system of claim 1, wherein the one or more soft tissue grafts completely fills a glenoid bone loss.

### Claim 8 (depends on 1)

The repair system of claim 1, wherein the one or more soft tissue grafts are in the form of a cuboid block.
