Abstract: A wicking component is integrated into an arthroscopically deployable bone anchor, and is intended to improve soft tissue-to-bone repair. Once deployed, the fibrous wick component extends from within the bone tunnel, out of the hole, and to the bone-tendon interface on the bone surface.

The system provides a biomimetic structure that stimulates the extracellular matrix to encourage cell attachment and potentially improve the healing response. The wick component does not need to be integrated into a suture anchor and installed when the suture anchor is deployed.
