Anchor for screw fixation of soft tissue to bone
First Claim
1. A bioabsorbable inlay for promoting soft tissue to bone attachment comprising:
- a bioabsorbable polymeric matrix;
a bioactive agent bound to the bioabsorbable polymeric matrix; and
a receptor for receiving an affixing member for affixing the bioabsorbable inlay between soft tissue and bone.

Abstract
The present invention relates to the field of orthopedics in addressing soft tissue to bone attachment. The embodiments of the present invention provide for a bioabsorbable inlay, a bioabsorbable inlay assembly, and a method to implant the bioabsorbable inlay between soft tissue and bone. Also provided is a means for facilitating soft tissue to bone attachment through the use of a bioabsorbable inlay, bounded with osteoconductive or osteoinductive materials, affixed at the interface of soft tissue to bone attachment sites. In an embodiment, the bioabsorbable inlay is formed into circular discs with holes for sutures to pass through and bounded with hydroxyapatite. The circular discs are then placed in communication between the soft tissue and bone at the appropriate site of attachment through the use of anchors and/or sutures. The bioabsorbable circular disc inlays are either overlaid or recessed into the bone.
